ABSTRACT:
Crude organic solutions of N,N-dialkylcarbamoylmethylphosphine oxide compounds can be purified by treatment with a first row transition metal salt to form a complex which can be treated to regenerate a purified solution of the compound. The first row transition metal can be selected from the monobasic acid salts of zinc, for example.
