AI Technical Summary

Problems solved by technology

Although polyoxyethylene ether emulsifiers of fatty alcohols overcome the shortcomings of alkylphenols, their emulsifying ability and influence on colloidal polymerization of polymers are quite different from those of alkylphenols, and the performance of emulsions is similar to that of alkylphenols. The emulsion ratio is also quite different; this is because the carbon number of the fatty alcohol in the fatty alcohol polyoxyethylene ether is mostly more than 12, the crystallinity is strong, the critical micelle concentration increases, the dosage increases, and the emulsifying ability decreases, and because the dosage increases, The water resistance of the emulsion film has declined; on the other hand, because the wetting performance of fatty alcohol polyoxyethylene ether is not as good as that of alkylphenol polyoxyethylene ether, it is found that the color development of the coating film is greatly reduced after being used in latex paint

Abstract

The invention provides alpha-phenylalkyl alcohol polyoxyethylene ether and a preparation method thereof. The alpha-phenyl alkyl alcohol polyoxyethylene ether is of a non-ionic type; and the molecular structure of the alpha-phenylalkyl alcohol polyoxyethylene ether comprises a hydrophobic group and a hydrophilic group, wherein the hydrophobic group is an alpha-phenylalkyl chain segment, the hydrophilic group is a polyoxyethylene ether chain segment, and a mol ratio of the hydrophobic group to the hydrophilic group is 1: (3-50). The APEO-free emulsifier, i.e., alpha-phenylalkyl alcohol polyoxyethylene ether, provided by the invention has good wetting, penetration, emulsification, dispersion, solubilizing and washing effect and can be used as an emulsifier, a textile auxiliary agent, a washing agent, a dispersant, a softener, a crude oil demulsifier, etc.; and the APEO-free emulsifier can totally replace an alkylphenol polyoxyethylene emulsifier and be extensively applied to industries like washing agents, personal care products, textile, papermaking, petroleum, pesticides, pharmacy, printing, synthetic rubber, aqueous emulsions, paints, printing ink, glue and plastics.
