THE DEMULSIFYING EFFECT OF MIXTURES OF POLYACRYLAMIDE WITH A SURFACTANT ON VASELINE EMULSIONS
Abstract
Technical emulsions of Vaseline and water stabilized by anionic surfactant — sulfonol (SF), cationic surfactant — cetylpyridinium bromide (CPB) and their mixtures with polyacrylamide (PAA) were obtained. It was shown that surfactant compositions with a polymer have a lower stabilizing effect on emulsions, which is associated with a decrease in the surface activity of surfactant – PAA complexes compared to individual surfactants. The isotherms of surface tension of surfactants — CPB and SF and their compositions with PAA — were obtained. A correlation was found between the surface tension of surfactant-PAA compositions and the demulsifying effect of surfactant-PAA compositions on Vaseline emulsions. The use of PAA compositions with surfactants opens up new possibilities for the development of effective demulsifies.
