ABSTRACT:
An aminomethylation reaction is disclosed wherein polymeric polyamines are produced. Polymeric polyolefins such as polybutadiene, ammonia, primary or secondary amines, and synthesis gas are reacted in the presence of a catalyst system comprising a ruthenium-containing catalyst, such as triruthenium dodecacarbonyl, and dimethyl formamide as a solvent.
The use of a two-phase solvent mixture consisting of N,N-dimethylformamide plus a hydrocarbon is particularly advantageous in that:
