Sažetak

Chlorsulfonic acid was successfully used as a catalyst in some esterifications. It was found that in the presence of chloirosulfonic acid an ethanolic solution of cyanoacetic acid is simultaneously hydrolyzed and esterified to give diethyl rnalonate with 82-84 % yield, based on chloroacetic acid.
