white powder. Low toxicity. Melting point 145 °c. Density 1.009g/cm3. Insoluble in water, ethanol and ether. With aromatic hydrocarbons and aliphatic hydrocarbons to form a colloid.
The molten stearic acid and excess sodium hydroxide solution are mixed to prepare soap solution, and then dilute aluminum sulfate solution is injected into the soap solution in the presence of alkali solution, and the double decomposition reaction is carried out, it is dehydrated into a crude product of hydroxyaluminum distearate, and finally washed and dried to obtain a finished product.
used as a raw material for metal rust inhibitor, Building Material waterproofing agent, paint and ink thickening agent, cosmetic emulsifier, plastic lubricant and so on.
