Abstract
1,125,730. Glycol hemiethers. CHEMISCHE WERKE HULS A.G. 14 Jan., 1966 [15 Jan., 1965], No. 1821/66. Heading C2C. Glycol hemiethers having the formula and/or are prepared by hydrogenating in the presence of a hydrogenation catalyst containing copper, nickel or cobalt, or an oxide or chromite thereof a dioxolane derivative of formula where each of R<SP>1</SP> to R<SP>6</SP> denotes a hydrogen atom or an alkyl, cycloalkyl, aryl or aralkyl group or two of the alkyl groups bound to the same carbon atom are joined to form a cycloalkane group. Preferred hemiethers are those in which R<SP>1</SP> and R<SP>2</SP> are n-alkyl groups of eight to fifteen carbon atoms and R<SP>3</SP> to R<SP>6</SP> are hydrogen. The preferred catalyst is a copper-chromium oxide catalyst. The catalysts may be supported, e.g. on alumina or silica. The process is preferably carried out at 50‹ to 350‹ C. and at a hydrogen pressure of 20 to 350 atmospheres. Examples describe the preparation of 2-(#-hydroxyethoxy) - n - tetradecane, 3 - (# - hydroxyethoxy) - n - undecane, 1 - (# - hydroxyethoxy)- n - hexane, # - hydroxyethyl benzyl ether, 2 - (# - hydroxyethoxy) - n - butane, 2 - (α- methyl - # - hydroxyethoxy) - n - propane, #- hydroxydimethyldiphenylethylcyclohexyl ether and # - - hydroxyethoxycyclohexane. Tetradecanol-(2), undecanol-(3) and n-hexanol are obtained as side products and may be reconverted to the starting products by dehydrogenation.
