化学的特性
Benzyl alcohol occurs in many essential oils and foods. It is a colorless liquid with a weak, slightly sweet odor. Benzyl alcohol can be oxidized to benzaldehyde, for example, with nitric acid. Dehydrogenation over a copper–magnesium oxide–pumice catalyst also leads to the aldehyde. Esterification of benzyl alcohol results in a number of important fragrance and flavor materials. Diphenylmethane is prepared by a Friedel–Crafts reaction of benzyl alcohol and benzene with aluminum chloride or concentrated sulfuric acid. By heating benzyl alcohol in the presence of strong acids or strong bases, dibenzyl ether is formed.

Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. |
| Preventive Measures | SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.Ventilation control: the basic ventilation methods are local exhaust ventilation and dilution or general ventilation....

| 相互作用 | Acetaminophen (APAP) toxicity is the most common cause of acute liver failure in industrialized countries. Understanding the mechanisms of APAP-induced liver injury as well as other forms of sterile liver injury is critical to improve the care of patients. Recent studies demonstrate that danger signaling and inflammasome activation play a role in APAP-induced injury. The aim of these investigations was to test the hypothesis that benzyl alcohol (BA) is a therapeutic agent that protects against APAP-induced liver injury by modulation of danger signaling. APAP-induced liver injury was dependent, in part, on Toll-like receptor (TLR)9 and receptor for advanced glycation endproducts (RAGE) signaling. BA limited liver injury over a dose range of 135-540 ug/g body weight or when delivered as a pre-, concurrent, or post-APAP therapeutic. Furthermore, BA abrogated APAP-induced cytokines and chemokines as well as high-mobility group box 1 release. Moreover, BA prevented APAP-induced inflammasome signaling as determined by interleukin (IL)-1(beta), IL-18, and caspase-1 cleavage in liver tissues. Interestingly, the protective effects of BA on limiting liver injury and inflammasome activation were dependent on TLR4 signaling, but not TLR2 or CD14. Cell-type-specific knockouts of TLR4 were utilized to further determine the protective mechanisms of BA. These studies found that TLR4 expression specifically in myeloid cells (LyzCre-tlr4-/-) were necessary for the protective effects of BA. BA protects against APAP-induced acute liver injury and reduced inflammasome activation in a TLR4-dependent manner. BA may prove to be a useful adjunct in the treatment of APAP and other forms of sterile liver injury. |

| 環境中動態 | TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of <5(2) and 29(3) indicate that benzyl alcohol is expected to have very high mobility in soil(SRC). Volatilization of benzyl alcohol from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.37X10-7 atm-cu m/mole(4). Benzyl alcohol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 9.4X10-2 mm Hg at 25 °C(5). Utilizing the Japanese MITI test, 94% of the Theoretical BOD was reached in 2 weeks(6) indicating that biodegradation is an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), Koc values of <5(2) and 27(3) indicate that benzyl alcohol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected to be an important fate process(4) based upon a Henry's Law constant of 3.37X10-7 atm-cu m/mole(5). According to a classification scheme(6), an estimated BCF of 1.4(SRC), from its log Kow of 1.10(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Utilizing the Japanese MITI test, 94% of the Theoretical BOD was reached in 2 weeks(9) indicating that biodegradation is an important environmental fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), benzyl alcohol, which has a vapor pressure of 9.4X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor phase benzyl alcohol is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 2 days(SRC), calculated from its rate constant of 2.3X10-11 cu cm/molecule sec at 25 °C(3). Benzyl alcohol does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC). |

| 毒性の概要 | Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.orgIDENTIFICATION: Benzyl alcohol is an aromatic organic alcohol, water-white in color with a faint aromatic odor and a sharp burning tasteit is a preservative, a solvent, and a local anesthetic. It is used in a wide variety of products including photographic developer for color movie filmsdyeing nylon filament, textiles, and sheet plasticssolvent for dyestuffs, cellulose esters, casein, waxesheat-sealing polyethylene filmsintermediate for benzyl esters and ethersbacteriostaticcosmetics, ointments, emulsionsball point pen inksstencil inks. HUMAN EXPOSURE AND TOXICITY: Benzyl alcohol has been found to be irritating to the skin at levels 3% or greater. Patch test with 0.65% benzyl alcohol did not produce irritation of the skin. Benzyl alcohol poisoning can cause the gasping syndrome in neonates. The infants had a typical course of gradual neurologic deterioration, severe metabolic acidosis, the striking onset of gasping respirations, thrombocytopenia, hepatic and renal failure, hypotension, cardiovascular collapse and death. In every infant, unmetabolized benzyl alcohol was identified in the urine. Hypersensitivity reactions may occur after parenteral or dermal exposure to benzyl alcohol. Acute reactions include urticaria, erythema, palpable edema, fatigue, nausea, diffuse angioedema, maculopapular rash, and fever. A delayed hypersensitivity reaction characterized by erythema, edema, and vesiculation may appear in 2 to 3 days after an immediate reaction to a single benzyl alcohol challenge in the same patient. Reports are available contraindicating the use of neuromuscular blocking agents containing benzyl alcohol. Use of these agents was not advised in neonates or in the epidural space. Benzyl alcohol 0.225 mg/mL, the clinically relevant concentration in triamcinolone acetonide (TA) following intravitreal injection, caused ultrastructural damage and impaired human retinal pigment epithelial cell function at 2 hr. Benzyl alcohol 9.0 mg/mL, the concentration in commercial TA suspensions, was toxic within 5 minutes. ANIMAL STUDIES: In a primary irritation study 10% benzyl alcohol applied in a 24-hour occlusive patch to the back of eight male albino rabbits did not cause irritation. Undiluted benzyl alcohol was moderately irritating when applied to the depilated skin of guinea pigs for 24 hr. Acute intravenous toxicity of benzyl alcohol was determined in mice. Clinical signs were convulsion, dyspnea and reduced motility in all strains for 24 hours. The slight decrease in body weight in the first week following treatment returned to normal in the second week. Microscopic examination revealed local nerve degeneration when 5% benzyl alcohol was injected into the side of a cat's faceat 10% local anesthesia was produced. In another experiment, rats were given oral doses of 50, 100, 200, 400, and 800 mg/kg for 13 weeks. The high dose produced clinical signs indicative of neurotoxicity including staggering, respiratory difficulty, and lethargy. Reduction in weight gain was noted in males at 800 mg/kg and females at equal to or greater than 200 mg/kg. The high dose animals also showed hemorrhages around the mouth and nose, and histological lesions in the brain, thymus, skeletal muscle, and kidney. Fifty pregnant mice were given 750 mg/kg/day benzyl alcohol in water by gavage on days 6-13 of gestation and were allowed to deliver. A decrease in the birth weight and weight gain in the pups was observed, but the chemical was not toxic to the mothers and had no effect on pup viability. Benzyl alcohol was tested for genotoxicity in 5 Salmonella typhimurium strains (TA1535, TA1537, TA97, TA98, and TA100) in the presence and absence of metabolic activation. The highest ineffective dose tested without toxicity in any S. typhimurium strains was 5.0 mg/plate. Slight inhibition of the background bacterial lawn occurred in cultures at 6.666 mg/plate but no significant change was seen in the results. In a mammalian cell genotoxicity assay using CHO cells, benzyl alcohol was negative without metabolic activation and positive with metabolic activation. |

説明
Benzyl alcohol is a component catalyst for epoxy resins. It is also contained in the color developer C-22.
天然物の起源
The free alcohol is often present in several essential oils and extracts of jasmine, tobacco, tea, neroli, copaiba, Acacia farnesiana Willd., Acacia cavenia Hook. and Arn., Robinia pseudacacia, ylang-ylang, Pandanus odoratissimus, Michelia champaca, Prunus laurocerasus, tuberose, orris, castoreum, violet leaves, clove buds and others. Also found in fresh apple, apricot, mandarin peel oil, high bush blueberry, raspberry, strawberry fruit, American cranberry and cooked asparagus.
来歴
LIEBIG and WO¨HLER first prepared benzyl alcohol from bitter almond oil (benzaldehyde) in 1832. The structure of benzyl alcohol was determined in 1853 by CANNIZZARO. CANNIZZARO used the reaction named after him, in which benzaldehyde is disproportionated into benzoic acid and benzyl alcohol through the action of an alkali.
使用
benzyl alcohol is a preservative against bacteria, used in concentrations of 1 to 3 percent. It can cause skin irritation.
一般的な説明
A clear colorless liquid with a pleasant odor. Slightly denser than water. Flash point 194°F. Boiling point 401°F. Contact may irritate skin, eyes, and mucous membranes. May be slightly toxic by ingestion. Used to make other chemicals.
製法・合成法
製造方法
Benzyl alcohol is prepared commercially by the distillation of benzyl chloride with potassium or sodium carbonate. It may also be prepared by the Cannizzaro reaction of benzaldehyde and potassium hydroxide.
純化方法
It is usually purified by careful fractional distillation under reduced pressure in the absence of air. Benzaldehyde, if present, can be detected by UV absorption at 283nm. It has also been purified by shaking with aqueous KOH and extracting with peroxide-free diethyl ether. After washing with water, the extract is treated with saturated NaHS solution, filtered, washed, dried with CaO and distilled under reduced pressure [Mathews J Am Chem Soc 48 562 1926]. Peroxy compounds can be removed by shaking with a solution of Fe2+ followed by washing the alcohol layer with distilled water and fractionally distilling it. [Beilstein 6 IV 2222.]
