실험 절차

Process according to claim 1, whereby the di-n-propyl acetonitrile is hydrolysed by means of 80% aqueous sulphuric acid, in the proportion of 3 to 5 g of dilute acid/g of nitrile, at a temperature of 80°-85° C., and then the crude di-n-propyl acetamide thus obtained is hydrolysed in the same aqueous sulphuric acid medium in the presence of 1.4 mol of sodium nitrite/mol of nitrile, at a temperature of 40°-50° C.
