Abstract

The invention discloses a preparation method of triphenylethylene phenol polyoxyethylene ether oleate, which utilizes triphenylethylene phenol polyoxyethylene ether and oleate as raw materials and is characterized in that triphenylethylene phenol polyoxyethylene ether and oleate are dehydrated and condensed under the action of methanesulfonic acid sulfonate catalyst to prepare the triphenylethylene phenol polyoxyethylene ether oleate, the adduct number of ethylene oxide in the triphenylethylene phenol polyoxyethylene ether ranges from 10 to 20, and the molar ration of the triphenylethylene phenol polyoxyethylene ether to the oleate is 1:0.9 to 1.0. The preparation method has the advantages of reasonable process, simplicity in operation, short reaction cycle and better service performance,and products are stable.

Description

technical field [0001] The invention relates to a preparation method of tristyrene phenol polyoxyethylene ether oleate. It belongs to the technical field of preparation of ester compounds in organic chemistry. Background technique [0002] Tristyrene phenol polyoxyethylene ether oleate has excellent performance and can be mixed with anionic and nonionic surfactants. It is mainly used as printing and dyeing auxiliaries, dispersing leveling agent and dyeing agent for various polyester fibers in high temperature and high pressure dyeing. Emulsifiers can also be used in metalworking oils and, in general industry, as components of detergents. [0003] Owing to the unique performance and wide application of oil surfactants, and the low toxicity, low irritation and easy biodegradation of oil products, they are environmentally friendly products, so the development and research of oil surfactants has attracted more and more attention. [0004] The synthesis of tristyrene phenol pol...
