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 method for synthesizing fatty acid isopropyl ester and its application in special oil. React under normal pressure for 3 to 5 hours to obtain fatty acid isopropyl ester; the catalyst is an N-alkylpyrrolidone group methylphosphoric acid ionic liquid catalyst. The present invention synthesizes fatty acid isopropyl ester by selecting N-alkylpyrrolidone group methyl phosphate ionic liquid catalyst, which has the characteristics of low reaction temperature, less catalyst addition, no introduction of new water-carrying agent, short reaction time and high esterification rate. , The acid value of the produced product is small.

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...
