Nature
white or yellowish powder. The melting point was 117-120 °c. Do not dissolve in water, ethanol, ether, soluble in lye, turpentine. With strong acids can be decomposed into stearic acid and the corresponding aluminum salts.
Preparation Method
with stearic acid as raw material, heating and melting, and sodium hydroxide solution for saponification reaction, and then with aluminum sulfate for double decomposition reaction, finally by washing, centrifugal dehydration, drying.
Introduction
In case of strong acid, it decomposes into stearic acid and corresponding salt.
Use
It is used as a lubricant remover in oil field operations. For the raw materials of metal rust inhibitor, waterproof agent of building materials, polishing agent of ink, thickening agent of cosmetics, etc. Aluminum Stearate is used as a smoothing agent and thickener in coatings, and also has the effect of improving the thixotropy of coating films.
