Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

Disposal Methods · 3 件

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Incineration: Succinic acid should be combined with paper or other flammable material. An alternate procedure is to dissolve it in a flammable solvent and spray the solutions into the fire chamber.

If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

Health Effects · 1 件

At acute doses or exposures succinic acid is a skin irritant. Chronically high doses of succinate can lead to succinylation or succination of a variety of enzymes. Partial succinate dehydrogenase deficiency (15% to 50% of normal reference enzyme activity) in skeletal muscle leads to elevated succinate levels and causes mitochondrial myopathy with various symptoms, for example, brain involvement, cardiomyopathy, and/or exercise intolerance.

Environmental Fate · 3 件

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 11(SRC), determined from a log Kow of -0.59(2) and a regression-derived equation(3), indicates that succinic acid is expected to have very high mobility in soil(SRC). Volatilization of succinic acid from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.6X10-13 atm-cu m/mole(SRC), derived from its vapor pressure, 1.91X10-7 mm Hg(4), and water solubility, 8.32X10+4 mg/L(5). Succinic acid is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 1.91X10-7 mm Hg at 25 °C(4). The anion form, which is the dominant form in the environment (pKa 4.16 and 5.6), will also not volatilize(SRC). Succinic acid has been observed to biodegrade in soil at rates ranging from 52 to 89% in 7 days to 71 to 95% in 84 days at an initial concn of 1000 ppm(6), suggesting biodegration may be an important environmental fate process in soil.

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 11(SRC), determined from a log Kow of -0.59(2) and a regression-derived equation(3), indicates that succinic acid is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 3.6X10-13 atm-cu m/mole(SRC), derived from its vapor pressure, 1.91X10-7 mm Hg(4), and water solubility, 8.32X1+4 mg/L(5). One of the pKa values of succinic acid is 4.21(6), indicating that this compound will exist in the dissociated form in the environment and anions generally do not adsorb more strongly to suspended solids and sediment than their neutral counterparts(7), and will not volatilize. According to a classification scheme(8), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Succinic acid, present at 100 mg/L, reached 78% of its theoretical BOD in 14 days using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(10), suggesting biodegradation may be an important environmental fate process in water.

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), succinic acid, which has a vapor pressure of 1.91X10-7 mm Hg at 25 °C(2), is expected to exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase succinic acid 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 6 days(SRC), calculated from its rate constant of 2.8X10-12 cu cm/molecule-sec at 25 °C that was derived using a structure estimation method(3). Particulate-phase succinic acid may be removed from the air by wet and dry deposition(SRC).

薬理情報

Mechanism of Action · 1 件

Succinate is an essential component of the Krebs or citric acid cycle and serves an electron donor in the production of fumaric acid and FADH2. It also has been shown to be a good "natural" antibiotic because of its relative acidic or caustic nature (high concentrations can even cause burns). Succinate supplements have been shown to help reduce the effects of hangovers by activating the degradation of acetaldehyde - a toxic byproduct of alcohol metabolism - into CO2 and H2O through aerobic metabolism. Succinic acid has been shown to stimulate neural system recovery and bolster the immune system. Claims have also been made that it boosts awareness, concentration and reflexes.

Metabolism/Metabolites · 2 件

Succinic acid is a normal intermediary metabolite and a constituent of the citric acid cycle. It is readily metabolized when administered to animals, but may be partly excreted unchanged in the urine if large doses are fed.

Succinic acid can be converted into fumaric acid by oxidation via succinate dehydrogenase.

Absorption, Distribution and ExcretionSuccinic acid occurs normally in human urine (1.9-8.8 mg/L).

Succinic acid can be produced 1) by oxidation of Butanediol-1,4 with Nitric acid. 2) by oxidation of Tetrahydrofuran with Nitric acid. 3) by hydrogenation of Fumaric acid or Maleic acid.

製造方法工業生産の分野においては、もしくはその脱水環化物である無水マレイン酸を接触的に水素添加する事で調製します。 また、既述のようにコハク酸はTCA回路の中間体であることから、微生物を用いた発酵生産も可能です。ただし、その生産性は低くこれまで実用化には至っていません。しかし、(財)地球環境産 業技術研究機構(RITE)のグループは、グルタミン 酸生産菌である Corynebacterium glutamicumをメタノリックエンジニアリングの技術を用いて機能改変する事で、コハク酸の発酵生産効率を大幅に上げる事に既に成功しています。他にも、神戸大学のグループは、光合成微生物の一種であるラン藻の遺伝子組み換え体を用いてコハク酸の生産性を大きく向上される事に成功しています。このように、コハク酸の微生物発酵に関してはその開発が進みつつあるといえます。 コハク酸が多く含まれる生物、食品 しじみ、あさり、かき、はまぐり
