STUDIES ON THE ASSOCIATION OF HPMBP WITH SOME AMINE EXTRACTANTS

Studies on association effect of HPMBP and different-amine extractants (N1923, DOA, TOA) in benzene and association constents of HPMBP and T OA in different diluents were carried out, The association compounds o f TOA and amine extractants exist widely, which were associated throug h hydrogen bond into 1 : 1 compounds. The order of association ability (TOA>DOA>N1923) was consistent to their extraction abilities. Therefo re, in different diluents, the association order of HPMBP and TOA was toluene>cyclohexane>n-hexane>benzene.
