ABSTRACT:
Alkylphosphines are made by a reaction of gaseous phosphine and the corresponding gaseous olefin in contact with at least one non-oxidizing acid catalyst. Products produced thereby are alkylphosphines which contain substantially no metallic or oxygenating impurities. The process is a continuous process and employs a mineral acid catalyst either in solid form or as a liquid supported on a solid, inert material.
