When a mixture of 127 g (1 mole) of caprolactim-methylether and 108 g (1 mole) of phenylhydrazine was heated from 140° to 200°C over the course of 6 hours, 34 g (theoretically 32 g of methanol) of a distillate with a pungent smell of ammonia passed over at boiling point 60° to 140°C. The distillation of the reaction product yielded, in addition to a first runnings of starting material and 35 g of distillation residue, 92 g of caprolactam-phenylhydrazone of boiling point 125°C/0.1 mm Hg, in the form of a yellow crystalline mass which assumed a resinous brown discoloration in air. The yield was only 45.5% of theory.
