1495594 Phosphonium salts E I DU PONT DE NEMOURS & CO 28 Jan 1975 3656/75 Heading C2P [Also in Divisions C3 and B5] Phosphonium sulphonate salts of the formulµ and the tetraphenylphosphonium, butyltrioctylphosphonium and octadecyltriphenylphosphonium analogues of salt A are prepared by reacting the corresponding phosphonium chloride or bromide with the sodium salt of the appropriate sulphonic acid. Butyltrioctylphosphonium bromide and octadecyltriphenylphosphonium bromide are prepared by quaternization of trioctylphosphine and triphenylphosphine respectively. |
