Abstract

In the production of alcohols and ethers from olefines containing less than four carbon atoms, an alkyl sulphate mixture containing a substantial quantity of dialkyl sulphate is subjected to a preliminary hydrolysis by intimately mixing with not substantially more than an equal weight of water and agitating, for instance at 70--80 DEG C. or at boiling point under reflux, until the mixture is homogeneous; and then distilling to recover the products and concentrate the sulphuric acid for use again. The distillation is continued until the density of the distillate reaches 0,999, when the sulphuric acid in the still will be of 67--72 per cent. When the water added is 0,75 of the weight of the alkyl esters, about equal quantities of alcohol and ether are obtained. By adding the water at 55--60 DEG C. the mixture reaches 70--75 DEG C. without heating. Polymerized olefines remain dissolved in the acid and may be carbonized and rendered separable by heating a few degrees above the normal boiling-point as described in Specification 422,022, [Group III].
