Phase Equilibria in the Sodium Perchlorate—Ethoxylated Alkylamine—Water System in the Temperature Range of 58–90°C

Abstract

The scheme of topological transformation of the phase diagram for systems composed of a water–ethoxylated surfactant binary system with a lower critical solution temperature and an inorganic salt possessing salting-in–salting-out effect upon temperature variation was experimentally proved in relation to the alkylamine ethoxylate (ethomeen C/15)–sodium perchlorate–water system. Two phase separation regions were detected in the system in the temperature range between 58 and 82°C.
