실험 절차

A mixture of 100 g (0.69 mol) of trifluoroacetaldehyde ethyl-hemiacetal and 169.1 g (0.69 mol) of 2,6-dichloro-4-trifluoromethylphenyl hydrazine is heated at 100° C. for 6 hours. After the volatile components have been removed, the residue is recrystallized from petroleum ether. 200 g (89%) of trifluoroacetaldehyde N-(2,6-dichloro-4-trifluoromethylphenyl)-hydrazone of melting point 45° C. to 46° C. are isolated.
