International Classification:

C07C 4106

US Classification:

568678

Abstract:

An improved process for preparing. beta. -(sec-alkoxy) ethanol which comprises reacting an olefin with ethylene glycol in the presence of a sulfuric acid or benzenesulfonic acid catalyst and sufficient sulfolane or alkyl-substituted sulfolane solvent to provide a one phase reaction medium, extracting the reaction products with an alkane and recovering the. beta. -(sec-alkoxy) ethanol product from the alkane extract.
