Claims6
A process for the production of N'-methylacethydrazide which comprises reacting acethydrazide, paraformaldehyde, and hydrogen, in a solvent and in the presence of a palladium catalyst, said solvent being selected from the group consisting of water, lower aliphatic alcohols, and mixtures thereof, at a temperature of from 20.degree. to 150.degree. C, a hydrogen partial pressure of from 1.0 to 10,000 psi, and an equivalent ratio of acethydrazide to paraformaldehyde of from 0.1/1 to 10/1.
A process for the production of N'-methylacethydrazide which comprises reacting acethydrazide, paraformaldehyde, and hydrogen in a solvent chosen from the group consisting of water, methanol, isopropanol, and mixtures thereof, in the presence of a palladium catalyst, at a temperature of from 50.degree. to 120.degree. C and a hydrogen partial pressure of 10 to 5,000 psi, wherein the molar ratio of acethydrazide to paraformaldehyde is from 0.33/1 to 3/1, and wherein the palladium catalyst is selected from the group consisting of palladium and palladium oxide.
