  • Patent number: 3948900
    Abstract: A process for the preparation of 1-methylpiperazine and 1,4-dimethylpiperazine as co-products is disclosed which provides a crude reaction product free of piperazine impurity. The process of the invention comprises mixing and reacting formaldehyde and piperazine at a molar ratio of more than 1.3 to less than about 2.0 and then hydrogenating the resulting reaction product carried in methanol as a major solvent in liquid phase at a temperature of about 60.degree.-130.degree.C. in the presence of a nickel or cobalt hydrogenation catalyst. The crude hydrogenated reaction product is free from piperazine impurity from which 1-methylpiperazine and 1,4-dimethylpiperazine can be readily separated in substantially pure form such as by simple fractional distillation.
