Abstract
271,169. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 22, 1926. Monoethers of glycols and their derivatives are obtained by the reaction of alkylene oxides upon monohydric alcohols in the presence of sulphuric acid or acid compounds thereof, alkali metal alcoholates ,or alkali salts of the lower fatty acids, these bodies acting as catalysts. According to examples :-(1) Ethylene oxide is added in the cold to methanol containing a little sulphuric acid and the product neutralized and fractionated to give glycol monomethyl ether; the ethers of ethyl, propyl, or isobutyl alcohol may be obtained similarly; (2) ethyl alcohol, containing a little sulphuric acid, and ethylene oxide vapour are atomized into the top of a packed tower and the product siphoned off from the bottom and distilled, giving glycol monoethyl ether: (3) a monomethyl ether of gamma-chlorpropylene, boiling at 168-170‹ C.. is obtained from epichlorhydrin, methanol, and sulphuric acid; (4) glycol monoethyl ether is obtained by heating ethyl alcohol and ethylene oxide with sodium acetate, or by passing the vapours of these substances over sodium acetate distributed upon a support; (5) sodium is dissolved in a large excess of glycol monoethylether, ethylene oxide is added, the product neutralized and distilled, giving an ethyloxyethyl ether of the formula HO.CH2.CH2.O.CH2.CH2OC2H5, boiling at 195‹ C., (6) monobutyl ethers of glycol are prepared by heating in an autoclave ethylene oxide with normal, iso-, or secondary butyl alcohol and a little sulphuric acid.
