Ethyl Acetate
Synonyms: Acetic acid ethyl ester, Ethyl ethanoate, Acetoxyethane
A colorless, volatile, flammable liquid, C4H8O2, having a fragrant, fruitlike odor: used chiefly as a scent in the manufacture of perfumes, flavorings, and confections, and as a solvent for paints, varnishes, and lacquers. Also called acetic ether.
Boiling Point: 77C (171F) Moderately soluble in water (9 g/100 mL)
CAS No.: 141-78-6
Molecular Weight: 88
Hazardous Decomposition Products:
Carbon dioxide and carbon monoxide may form when heated to decomposition.
Incompatibilities:
Avoid heat, flame and other sources of ignition. Contact with nitrates, strong oxidizers, strong alkalis, or strong acids may cause fire and explosions. Will attack some forms of plastic, rubber, and coatings.
----------------------------------------------------
The common use of ethyl acetate as solvent for preparing -tocopherol (vitamin E) can be attributed to its appropriate solubility for trimethylhydroquinone. Ethyl acetate, however, is accompanied by problems such that upon washing a reaction mixture subsequent to the reaction, ethyl acetate is caused to transfer at a high rate into a water layer, its recovery rate is low, and treatment of waste water from the washing is difficult. Further, ethyl acetate is extremely prone to hydrolysis under conditions other than neutral conditions, especially under basic conditions. It also tends to undergo a transesterification. Due to these properties, there is a further problem that when ethyl acetate is employed in the preparation of -tocopherol, by production of -tocopheryl acetate is unavoidable.

“The acute toxicity of ethyl acetate is low. Ethyl acetate vapor causes eye, skin, and respiratory tract irritation at concentrations above 400 ppm. Exposure to high concentrations may lead to headache, nausea, blurred vision, central nervous system depression, dizziness, drowsiness, and fatigue. Ingestion of ethyl acetate may cause gastrointestinal irritation and, with larger amounts, central nervous system depression. Eye contact with the liquid can produce temporary irritation and lacrimation. Skin contact produces irritation.
Ethyl acetate is regarded as a substance with good warning properties. No chronic systemic effects have been reported in humans, and ethyl acetate has not been shown to be a human carcinogen, reproductive or developmental toxin.”

What are the chances that a stirred solution of ethyl acetate will fucking blow my face off if I slowly add dry NaOH to it? Or am I better off saturating water with the hydroxide, then drip it into ethyl acetate? I want as little water to be involved as possible, so that high octane booze can be obtained when the resulting mixture of sodium acetate + ethanol is distilled. How’s that for pure moonshine? No methanol contamination or nasty flavors. A small jello-shot made from that would put me on my ass, ha! A while back, I got this production idea from someone who makes her hooch from ethyl benzoate, water, KOH.
What carboxylic acid ethyl ester would you use as an ethanol precursor?
