Abstract
In the preparation of ethyl alcohol from a solution of diethyl sulphate in concentrated sulphuric acid, said solution is diluted with water to a 40-55 weight per cent sulphuric acid concentration, the major portion of the diethyl sulphate is hydrolysed in a first hydrolysis zone maintained at 80-90 DEG C., a stream of the partly-hydrolysed solution is passed through a second hydrolysis zone maintained at 80-95 DEG C. with sufficient residence time for substantially complete hydrolysis of the remaining diethyl sulphate, and alcohol is stripped with steam from the exit stream. The details of operation are as described in Specification 628,002.
