Problems solved by technology

Synthesis of terpineol with turpentine as raw material will produce a large amount of by-product terpinene, which accounts for about 20% to 30% of the output of terpineol. my country is rich in turpentine resources and is the country with the largest output of rosin and turpentine One, the amount of by-product terpinene produced by the synthesis of terpineol is huge every year. Terpinene is a mixture of isomers with very similar properties. It is very difficult to separate, so it can only be used as a low-grade solvent use, it is difficult to produce greater economic benefits

Abstract

The present invention discloses a method for preparing an anti-rust emulsifier by using an industrial by-product terpinene. The method is characterized in that the main components such as alpha-terpinene and alpha-butenoic acid in terpinene are subjected to an addition reaction, the produced addition product terpinene butenoic acid is subjected to an epoxidation reaction under the effect of an acid catalyst, the generated epoxidated terpinene butenoic acid compound and concentrated sulfuric acid are subjected to a sulfonation reaction, and finally alkali neutralization is performed so as to generate the hydroxyl-containing terpinene butenoic acid sodium sulfonate anti-rust emulsifier. According to the present invention, the industrial by-product terpinene with characteristics of adequate source and low cost is adopted as the raw material to synthesize the emulsifier having the good anti-rust property; and the reaction operation is simple and is easy to perform, and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of emulsifier synthesis, in particular to a method for preparing an antirust emulsifier by using industrial by-product terpinene. Background technique [0002] Emulsifier is an important part of water-based processing fluid. With the rapid development of mechanical processing industry and water-based processing fluid, lubricants are also constantly being developed. Synthesis of terpineol with turpentine as raw material will produce a large amount of by-product terpinene, which accounts for about 20% to 30% of the output of terpineol. my country is rich in turpentine resources and is the country with the largest output of rosin and turpentine One, the amount of by-product terpinene produced by the synthesis of terpineol is huge every year.
