Solid super acid is a new type of solid acid catalyst researched and developed in recent years. Compared with traditional liquid acid catalysts, it has the advantages of high catalytic efficiency, low equipment corrosion, and convenient post-treatment. Esterification is an important reaction in the synthesis of fine chemicals. Currently, unenvironmental liquid acid catalysts are usually used in industrial production, and it is difficult for liquid acid catalysts to catalyze the synthesis of higher alcohol esters of stearic acid.

Stearyl stearate has good lubricity and thermal stability, and can be used as a low-temperature lubricant, plasticizer for rubber and plastics, softener, cosmetics and food additives, etc. It is widely used in light industry, chemical industry, biological engineering, Metallurgy and other industries have very good application prospects. Experiments have tried to apply solid acid catalysts to the synthesis of stearyl stearate, which provides a new way for the synthesis of long-chain fatty acid higher alcohol esters.

Preparation of Stearyl Stearate

Method 1: Preparation of Stearyl Stearate: Add a certain amount of stearic acid, stearyl alcohol and solid acid catalyst into a 100mL three-necked bottle equipped with an electric stirrer, a thermometer, and a reflux condenser to conduct a heating reflux reaction. After the reaction, filter while hot, transfer to a small beaker, wash the product three times with 80% ethanol aqueous solution, solidify and air-dry, then vacuum-dry to obtain a white waxy solid. Calculate yield by weighing. The melting point and infrared spectrum of the product were determined. The product is a white waxy solid with a melting range of 61-63°C and a literature value of 62-64°C. The infrared spectrogram was obtained after KBr compression, and the spectrogram data analysis is as follows: 2954.1~2850.2cm-1 is the saturated C-H stretching vibration absorption peak; 1732.3cm-1 is the characteristic absorption peak of ester carbonyl C=O; 1467.6cm-1 1 is the bending vibration of methyl and methylene; 1180.6cm-1 is the stretching vibration of C-O single bond, which is in line with the characteristics of higher alcohol stearate. The above analysis can confirm that the experimental product is Stearyl Stearate.

Method 2: <Add 0.02mol of stearyl alcohol and a certain amount of stearic acid to a 250mL three-necked bottle<Then quickly add the catalyst p-toluenesulfonic acid (PTSA)<Put the three-necked bottle in the microwave cavity<Assemble the reflux device , Molecular sieve dehydrator and electric stirrer; set time <synthesis under certain microwave power; completion of reaction <wash with hot 95% ethanol solution <remove catalyst and a little impurity <get white waxy solid product <dry <weighing< Calculate the yield. The optimum conditions are: taking stearyl alcohol 0.02mol as the benchmark <the ratio of the substance of stearyl alcohol to stearic acid is 1: 1.2<catalyst consumption is 0.2g<microwave radiation power is 514W<microwave radiation time For 40min< productive rate can reach 94.35%.
