Abstract

a -Glycols, the corresponding di- or polyglycols and alkyl ethers of a -glycols are prepared by reaction of 1 : 2-alkylene oxides with a compound of the general formula R-OH, where R is hydrogen or an alkyl radical, in the presence of an organic hydrogen-active cation-exchange material. The reaction may be carried out under atmospheric or slightly higher pressures. Reaction with water yields the glycols, polyglycols being obtained by increasing the proportion of epoxide used. Methyl, ethyl, butyl and so on ethers of the a -glycols result when the alcohols are employed. In examples: (1) ethylene oxide is bubbled through water containing in suspension a finely-divided resorcinol-formal hydrogen activated cation exchanger, the temperature being maintained at 41 DEG C. and the products comprise 90 per cent a -glycols with higher glycols; (2) ethyl alcohol and gaseous ethylene oxide are passed in counter-current flow through a hydrogen-activated cation-exchanger of sulphonated polystryrolene at a temperature maintained below 35 DEG C. and glycol ethyl ether is recovered from the resulting alcoholic solution. Propylene oxide is also mentioned as a reagent and sulphonated lignites and phenolformaldehyde resins are given as further examples of suitable cation-exchangers. The Specification as open to inspection under Sect. 91, relates to the production of glycols and their derivatives by reaction of 1 : 2-alkylene oxides with compounds of the formula R-OH, where R may be hydrogen or an alkyl, aryl or aralkyl radical, in the presence of an acid catalyst insoluble in water and the glycol solutions formed and natural and artificial zeolites are mentioned. This subject-matter does not appear in the Specification as accepted.
