Process for the preparation of 4,4'-diaminoditolylmethane

摘要

A process for the production of 4,4'-diaminoditolylmethane comprises reaction of o-toluidine with formaldehyde in the presence of an acid catalyst whereby the ratio of acid catalyst to o-toluidine is 0.8-1.2 equivalents of acid per mole of o-toluidine. providing a process for the production of 4,4'-diaminoditolylmethane.
