Problems solved by technology

However, the water-carrying agents used in current literature reports are generally cyclohexane, benzene, and toluene, which are highly toxic and are not suitable for the application of fatty acid isopropyl esters in cosmetics.
In addition, at present, sulfuric acid is mostly used as catalyst in the production of fatty acid isopropyl ester, the equipment is severely corroded, the esterification rate is not high, and the post-treatment of the product is complicated

Abstract

The invention discloses a synthetic method of isopropyl fatty acid ester and application of the isopropyl fatty acid ester to special oil. The synthetic method is characterized in that organic acid and isopropanol are used as raw materials and react for 3 to 5 hours at 85 DEG C to 95 DEG C and ordinary pressure under the catalytic action of a catalyst, so as to obtain the isopropyl fatty acid ester, and the catalyst is an N-alkyl pyrrolidone-group methyl phosphate ionic liquid catalyst. The N-alkyl pyrrolidone-group methyl phosphate ionic liquid catalyst is selected for synthesizing the isopropyl fatty acid ester, so that the synthetic method has the characteristics of low reaction temperature, less catalyst addition, no need of water-carrying agent, short reaction time, high esterification rate and the like, and an acid value of a produced product is low.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for synthesizing fatty acid isopropyl ester and its application in special oil. Background technique [0002] Fatty acid isopropyl ester, which has excellent anti-wear properties of synthetic esters, good low-temperature properties, high-temperature stability, and low volatility, so it can meet higher lubrication requirements; in addition, it has antistatic properties and makes hair combable Good, smooth, good for protecting damaged hair. Fatty acid isopropyl ester is used in cosmetics as an oily component of ointment, cream, and honey, which can make the dispersion effect of fillers and pigments better. It is an excellent oily solvent, especially suitable for application in the special oil industry. [0003] Fatty acid isopropyl ester has the characteristics of excellent lubricating performance, high viscosity index, high biodegradation rate and low toxicity. It is a k...
