Abstract
A process for the production of an ether having a hydroxy, alkoxy or aralkoxy group in the 2- or 3-position comprises reacting in the liquid phase a cyclic ketal of formula <FORM:1020500/C2/1> where each R independently is C1-8 alkyl or C6-10 aryl; each R1 independently is hydrogen, C1-8 alkyl or C6-10 aryl; X is hydrogen, hydroxy, C1-8 alkyl or C6-10 aryl; m is 0 or 1 and n is 0, 1, 2 or 3 with molecular hydrogen in the presence of a metal of Group VIII as hydrogenation catalyst and an acidic substance (including Lewis acids). Other metal promoters, e.g. chromium, may be present. Solvents are optionally used, preferably those alcohols or ether alcohols equivalent to parts of the cyclic ketal starting material. In examples: mixtures of ethylene glycol mono-and di-isopropyl ethers are obtained from 2,2-dimethyl - 1,3 - dioxolane and a mixture of 1-isopropoxy - 2 - propanol, 2 - isopropoxy - 1-propanol and propylene glycol diisopropyl ether from 2,2,4-trimethyl-1,3-dioxolane.
