실험 절차

The acid calcium epoxysuccinate obtained by the epoxidation was reacted in acetic acid with the aid of concentrated sulphuric acid to form calcium sulphate and epoxysuccinic acid. For this purpose, 50 g. of acid calcium epoxysuccinate, having a calcium content of 11.9% by weight, and 15 g. of concentrated sulphuric acid were introduced, with stirring, into 300 ml. of glacial acetic acid. The suspension was kept at 20° C. for 2 hours with stirring, and then heated to 70° C. After 2 more hours the reaction was complete and the calcium sulphate was filtered off. The calcium sulphate was washed three times with 30 ml. of glacial acetic acid.
