ethyl sulphide

Chem.: Thic-ethylic ether, (C2H5)2S. A colorle oily pungent liquid boiling at ibid by pa ing ethyl-chloride into an alcoholic solution Chem.: C2H5OH. [ALCOHOL.] Ethyl-alcohol 91°; it is very inflam The American Dictionary and Cyclopedia be obtained from acetic acid by converting the acid into acetyl chloride by distillation with phosphorus pent a chloride, and acting on a mixture of amalgam, which decomposes the acetic acid, liberating hydrogen, which acts on the acetyl chloride, CH3 CO-Cl, converting it into aldehyde, which, by the further action of hydrogen, is converted into of pota ium sulphide. chloride and glacial acetic acid with sodium alcohol, and this is converted by acetyl chloride into acetic ether. This is then saponified by distilling with potash, yielding pota ium acetate and ethyl-alcohol. Ethyl-alcohol has been detected in several growing plants, as in the fruit of the parsnip ( Pastinaca sativa ). It is formed during the fermentation of dough, and mostly evaporates during baking, but bread contains 0.314 per cent. of alcohol. A mixture of one part snow and two parts of 70 per cent. alcohol at 0°, lowers the temperature to-20 To detect alcohol, oxidize with sulphuric acid and permanganate of pota ium, then add sodium thiosulphate to render the solution colorle . The aldehyde formed gives a violet color on the addition of a drop of a solution of magenta. Or, warm the liquid and add a fragment of iodine, and then caustic potash till it is colorle ; on cooling, it deposites a yellow powder which, under the microscope, appears as six-sided plates.
