DIPHASIC ACIDO-BASIC PROPERTIES OF ORGANOPHOSPHORUS ACIDS.

Abstract

ABSTRACT The diphasic acldo-basic properties of three dialkylorgeno-phosphorus odds, namely di-2-ethylhexylphosphoric acid (DEHPA),2-ethyl-hexylphosphonlc acid, mono-2-ethylhexyl ester marketed as PC 88A and di(2,4,4-trimethylpenty1) phosphinic acid marketed as CVANEX 272, and their ability to form aggregates have been investigated by diphasic acidimetry in presence of 1 mol.dm-3 NaC104 and computer simulation, A mathematical model, which is equivalent to the reality, is proposed.
