Abstract

Ethylene glycol is prepared by the hydration of ethylene oxide in the presence of a trihalogenoacetic acid which is subsequently removed from the reaction product by thermal decomposition. In an example, ethylene oxide is hydrated at about 60 DEG C. in the presence of trichloroacetic acid which is subsequently decomposed into chloroform and carbon dioxide by heating at 100 DEG C., and p ethylene glycol is separated from di- and triethylene glycol by fractional distillation. The Specification as open to inspection under Sect. 91 states that the hydration may be effected in the presence of any organic acid which can be decomposed at a temperature above the hydration temperature of ethylene oxide. This subject-matter does not appear in the Specification as accepted.
