Acetone ethyl mercaptol

Acetone Ethyl Mercaptol.—50 gms. ethyl mercaptan (see Preparation 306) are added to 20 gms. acetone aqd 6 gms. anhydrous calcium chloride. Dry hydrochloric acid gas is passed in, the temperature being kept below 25° by external cooling. When saturated with acid the mixture is allowed to stand overnight, and washed with water. The layer of mercaptol is separated and dried over calcium chloride, and fractionally distilled. Unchanged ethyl mercaptan passes over first, and then the mercaptol at 190°. [Pg.396]

Ethyl mercaptol—(CHs)a = C = (SCiiHii)j-is formed as one of the steps in the manufacture of sulfonal. It is produced by the action of dry HCl upon a mixture of acetone and ethyhner-captan, or upon a mixture of sodium ethylthiosulfate, CaHs, SO,ONa, and acetone. It is a mobile liquid, whose odor is not disagreeable. When heated it begins to boil at a-bout 80° (176° P.) and the temperature rises rather regularly to 193° (377°.6 P.). [Pg.298]
