EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.;SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.;INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.;INGESTION: DO NOT INDUCE VOMITING. Volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

Study of 30 workers exposed chronically to 15-50 mg of ethyl acetate in addition to 20 to 80 mg of amyl acetate/L of air showed no ... abnormalities in cornea, merely hyperemia of bulbar conjunctiva. ... Prolonged inhalation may be damaging to lung, liver, kidney, & heart. ... No effect on eyes ... known from systemic absorption.

Ethyl acetate in combination with toluene appeared to produce a mixture of lower toxicity than that of either compound alone. Mixing of ethyl acetate with propylene oxide, propylene glycol, or formalin appears to decr its LD50 value, but its toxicity increases in combination with morpholine, ethylene glycol, or ethyl alcohol.

In order to determine the lung disease potential of waterproofing sprays, several components of suspected sprays, as well as a commercial spray, were tested on CD-l-mice. Mice placed in inhalation chambers were exposed to aerosols containing one or more of the suspected components, including n-heptane, ethyl-acetate, fluororesin, silicone, and a commercial spray. An intermittent inhalation methods was used to prevent the solvents from causing anesthetic death. Mice were sacrificed 1 hour after the end of exposure. The lungs of both exposed and control mice were isolated and examined microscopically for any changes. The amounts released of the were similar. Mice exposed to the commercial and fluororesin sprays were cyanotic and depressed for 1 hour, while those exposed to the other sprays were cyanotic for only several minutes. In almost all mice exposed to the commercial spray, significant changes relative to the controls included a thickened pulmonary alveolar septa, cellular infiltration, fused and hemorrhaged alveolar walls, and diminished alveoli. Fluororesin particles were found in the alveolar space. Significantly more pronounced pathological changes were discovered in mice exposed to the fluororesin spray, relative to the commercial spray. In mice exposed to the silicone spray, significant differences were observed in alveolar collapse and hemorrhage, compared to the controls. The lungs of mice exposed to the N-heptane, ethyl-acetate, and fluororesin free sprays were similar to control lungs. In mice exposed to the silicon resin free spray, significant changes, relative to the commercial spray group, included alveolar collapse, hyperemia, hemorrhage and increased thickness and cellular infiltration of the septum. /It was/ concluded that ethyl-acetate and n-heptane contained in waterproofing sprays do not cause pulmonary disorders. Instead, fluororesin is implicated in respiratory disorders caused by such sprays.

Environmental Fate · 3 条

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 18(SRC), determined from a log Kow of 0.73(2) and a regression-derived equation(3), indicates that ethyl acetate is expected to have very high mobility in soil(SRC). Volatilization of ethyl acetate from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.34X10-4 atm-cu m/mole(4). Ethyl acetate is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 93.2 mm Hg at 25 °C(5). Utilizing the Japanese MITI test, 95% 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), an estimated Koc value of 18(SRC), determined from a log Kow of 0.73(2) and a regression-derived equation(3), indicates that ethyl acetate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon a Henry's Law constant of 1.34X10-4 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 9 hrs and 6 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Utilizing the Japanese MITI test, 95% of the Theoretical BOD was reached in 2 weeks(7) 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), ethyl acetate, which has a vapor pressure of 93.2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyl acetate 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 9 days(SRC), calculated from its rate constant of 1.6X10-12 cu cm/molecule-sec at 25 °C(3). Ethyl acetate 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).

Metabolism/Metabolites · 4 条

... The current study was aimed at quantitating the extent of metabolism of inspired ethyl acetate in the upper respiratory tract (URT) of the F344 rat and Syrian hamster. Ethyl acetate deposition was measured in the surgically isolated URT of these species under constant velocity unidirectional flow conditions. The degree of metabolism was estimated by mathematic modeling based on a simple venous-equilibration approach and by direct comparison of deposition efficiencies in naive and carboxylesterase-inhibited animals. Ethyl acetate deposition efficiencies averaged between 10 and 35% in the rat URT and 36 and 72% in the hamster. Carboxylesterase inhibition decreased deposition in both species. Both the modeling efforts and the direct comparisons between naive and inhibited animals indicated that significant amounts of the deposited ethyl acetate were metabolized in the URT of both species with the extent of metabolism being more pronounced in the hamster. Specifically, 40-65% of the deposited ethyl acetate was metabolized in the URT of the rat compared to 63-90% in the hamster. This first-pass metabolism (i) increased URT deposition efficiencies; (ii) led to production of high metabolite levels in URT tissues; and (iii) decreased the amount of parent ethyl acetate available for absorption into the bloodstream in the URT.

Because of the abundance of nonspecific esterases, one might expect the common solvent ethyl acetate (EtAc) to be hydrolyzed to ethyl alcohol (EtOH) in vivo. It would then be possible to demonstrate EtOH accumulation following exposure to EtAc vapor. Preliminary studies showed that rat blood incubated at 37 °C does hydrolyze EtAc to EtOH, with a half-time of approximately 65 min. Analyses were done by gas chromatography. To study this reaction in vivo, rats were anesthetized with pentobarbital, and cannulae were inserted into the femoral arteries. EtAc was injected ip as a 25% () solution in corn oil (1.6 g/kg) and blood samples were drawn periodically. Hydrolysis was very rapid in vivo, with a half-time estimated at 5-10 min. Inhalation studies were then carried out by exposing anesthetized rats to several concentrations of EtAc vapor via an endotracheal tube. When EtAc concentrations were increased above 2000 ppm, EtAc absorption exceeded EtOH oxidation, leading to an accumulation of EtOH in the blood. Although blood EtOH concentrations increased steadily to over 0.10 g/100 mL in 5 hr, EtAc remained consistently below 0.01 g/100 mL and did not change throughout the course of the experiment, again indicating rapid hydrolysis. The data indicate that EtOH will accumulate during exposure to EtAc if the ambient concentration of EtAc is sufficiently high.

... Ethyl acetate ... metabolism produces corresponding ethyl alcohol & is partly excreted in exhaled air & urine & partly metabolized.

Metabolic studies in the rat have revealed an approximate 2000 ppm no-effect level. At higher levels, the rate of hydrolysis of ethyl acetate appeared to exceed ethanol oxidation, leading to its accumulation in the vascular system. Also, when it was injected intraperitoneally at 1.6 g/kg, hydrolysis to acetic acid and ethanol occurred rapidly. Intraperitoneal injections of 1 mL/kg to male rats for 8 days increased the blood pyruvic and lactic acid content considerably and also elevated the glycolytic enzymatic activity.

Absorption, Distribution and Excretion... The primary route of absorption responsible for the toxicity of ethyl acetate is inhalation.

生产方法1酯化法由乙酸与乙醇在硫酸存在下直接酯化而得,生产工艺上有连续与间歇之分。(1)间隙工艺。将乙酸、乙醇和少量的硫酸加入反应釜,加热回流5-6h。然后蒸出乙酸乙酯,并用5%的食盐水洗涤,氢氧化钠和氯化钠混合溶液中和至PH=8。再用氧化钙溶液洗涤,加无水碳酸钾干燥。最后蒸馏,收集76-77℃的馏分,即得产品。(2)连续工艺。1:1.15(质量比)的乙醇和乙酸连续进入酯化塔釜,在硫酸的催化下于105-110℃下进行酯化反应。生成的乙酸乙酯和水以共沸物的形式从塔顶馏出,经冷凝分层后,上层酯部分回流,其余进入粗品槽,下层水经回收乙酸乙酯后放弃。粗酯经脱低沸物塔脱去少量的水后再入精制塔,塔顶可得产品。此工艺较间隙法好。2乙醛法乙醛在乙醇铝催化下生成乙酸乙酯,将乙醛、乙醇铝等连续加入两个串联的反应器,于0-20℃下进行反应,第二反应器的出口转化率可达99.5%以上,然后经蒸馏得乙酸乙酯。收率达95%-96%,此工艺比较经济。
