Title:

PROCESS OF DISPERSING THE MIXTURE OF HIGHER ALIPHATIC ALCOHOL

Document Type and Number:

WIPO Patent Application WO/2010/102480

Kind Code:

A1

Abstract:

A process of dispersing the mixture of natural higher fatty alcohol and synthetic higher aliphatic alcohol into water, which is in the technical field of fine chemical industry. The emulsion mixture of natural higher fatty alcohol and synthetic higher aliphatic alcohol obtained by such process comprises: (1) 1-30% of 14-30C synthetic higher aliphatic alcohol; (2) 1-15% of 12-18C natural higher saturated fatty alcohol; (3) 1-15% of waxes; (4) 0.1-5% of an nonionic surfactant of formula MO(EO)m(PO)nH, where M is alkyl group or phenyl group which is an starter group of the nonionic surfactant; (5) 0.1-5% of one or more anionic surfactants selected from sulfonated castor oil salt, sulfonated fatty acid glyceride, alkyl sulfate, alkoxy sulfate, alkyl-aryl sulfonate and alkyl polyoxyethylene ether sodium sulfate; (6) 0.1-5% of thickening agents; (7) 60-95% of dispersant water. The process comprises: (1) mixing the components of synthetic higher aliphatic alcohol, natural higher fatty alcohol, waxes, nonionic surfactants and anionic surfactants at a certain ratio, then heating to 80-95oC; (2) adding water with an temperature of 60-80oC slowly to the mixture and emulsifying at an temperature of at least 60 oC; (3) after all the hot water added to the mixture, the mixture being charged into an colloid mill; (4) cooling to 30-40 oC followed by adding thickening agents to the mixture and stirring, then said emulsion mixture is obtained.
