What is Stearyl Stearate?

In recent years, there has been significant research and development in solid super acid, a novel type of solid acid catalyst. This innovative catalyst offers several advantages over traditional liquid acid catalysts, including high catalytic efficiency, minimal equipment corrosion, and convenient post-processing. The esterification reaction, which plays a crucial role in the synthesis of fine chemicals, is particularly challenging for liquid acid catalysts to catalyze the synthesis of higher alcohol stearate esters.

Stearyl stearate is a highly valuable compound known for its excellent lubricity and thermal stability. It finds applications as a low-temperature lubricant, plasticizer, softener, as well as in cosmetics and food additives for rubber plastics. Its versatility makes it widely used in various industries such as light industry, chemical industry, bioengineering, and metallurgy. To meet the growing demand, researchers have explored the use of solid acid catalysts in the synthesis of stearyl stearate, offering a promising new approach to produce long-chain fatty acid higher alcohol esters.

Stearyl Stearate Uses

Stearyl Stearate is a versatile compound known for its excellent lubricity and thermal stability. It finds applications as a low-temperature lubricant, plasticizer, softener, and cosmetic and food additive in rubber and plastic industries. Additionally, it is extensively used in light industry, chemical industry, bioengineering, metallurgy, and other sectors. The compound holds great potential for various applications, making it highly sought after.

Stearyl Stearate Preparation

Method 1: To prepare stearyl stearate, a 100 ml three-necked flask with an electric stirrer, thermometer, and reflux condenser is used. Stearic acid, stearyl alcohol, and a solid acid catalyst are added to the flask, and a heating reflux reaction is carried out. After completion, the mixture is hot filtered and transferred to a small beaker. The product is washed three times with 80% ethanol solution, solidified, and dried in the air. Vacuum drying is then performed to obtain a white waxy solid. The yield is determined by weighing the product. The identity of the product is confirmed by measuring its melting point and conducting infrared spectroscopy. The product should be a white waxy solid with a melting point ranging from 61 to 63°C, which matches the literature values of 62 to 64°C. Infrared spectra are obtained after preparing KBr samples. The spectral analysis indicates that the product exhibits a saturated C-H stretching vibration absorption peak at 2954.1~2850.2cm-1, a characteristic ester carbonyl C=O absorption peak at 1732.3cm-1, a bending vibration of methyl and methylene at 1467.6cm-1, and a stretching vibration of C-O single bond at 1180.6 cm-1, which is consistent with the characteristics of higher alcohol stearate. This analysis confirms that the experimental product is indeed stearyl stearate.

Method 2: In a 250 ml three-necked flask, 0.02 mole of stearyl alcohol and a specific amount of stearic acid are added. The catalyst p-toluenesulfonic acid (PTSA) is quickly added, and the flask is placed in a microwave cavity. The setup includes a reflux device, molecular sieve dehydrator, and electric stirrer. The microwave power is set to a certain level, and the reaction time is controlled accordingly. After the reaction is completed, the mixture is washed with hot 95% ethanol solution, and the catalyst and impurities are removed. The resulting product is a white waxy solid, which is then dried, weighed, and the yield is calculated. The conditions for this method are as follows: 0.02 mole of stearyl alcohol is used as the base, the material ratio of stearyl alcohol to stearic acid is 1:1.2, the amount of catalyst is 0.2 grams, the microwave radiation power is 514 watts, and the microwave radiation time is 40 minutes. The collection rate can reach 94.35%.
