Application of stearic acid 57-11-4 Stearic acid, namely octadecanoic acid, molecular formula C18H36O2, is produced by the hydrolysis of oil and is mainly used for the production of stearate. Dissolve each gram in 21ml ethanol, 5ml benzene, 2Chemicalbookml chloroform, or 6ml carbon tetrachloride. Mainly used in the production of stearate: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.

The main purpose

Stearic acid is mainly used in the production of stearate: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, stearic acid Potassium. Widely used in cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, water repellants, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals, and other organic chemicals.

In addition, Stearic acid can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a polish for wax paper, an emulsifier for glyceryl stearate, and the like. This product is used in the food industry as a lubricant, a defoamer, and a raw material for food additives such as glycerol stearate, sorbitan stearate, and sucrose ester. Stearic acid is used as the raw material of auxiliary agents and the raw material of daily chemical products. Stearic acid is widely used in the manufacture of PVC plastic pipes, sheets, profiles, and films.

Stearic acid is a heat stabilizer for PVC, which has good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent “coking” during processing, is an effective heat stabilizer in PVC film processing, and protects the finished film from exposure to sulfides discoloration.

Application field

1. Rubber industry
Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanization activator in natural rubber, synthetic rubber, and latex. It can also be used as a plasticizer and softener. In the process of producing synthetic rubber, stearic acid needs to be added as an emulsifier. In the production of foam rubber, stearic acid can be used as a foaming agent, and stearic acid can also be used as a mold release agent for rubber products.

Stearic acid is added as auxiliary material, and the proportion added is very small, usually 0.5-3 parts of stearic acid per hundred parts of rubber, but it is indispensable. As a vegetable oil fatty acid, in the processing of rubber (tire), after adding it in a certain proportion, it can be summed up in the following four aspects:

  • 1. Softening and plasticizing;
  • 2. As an external lubricant;
  • 3. Stearic acid is beneficial to the full diffusion of carbon black, silica and zinc oxide;
  • 4. Reaction with zinc oxide or alkaline accelerator can promote its activity, and it is also the main vulcanization accelerator, which can play the role of the second accelerator. Accelerates hardening.

2. Cosmetics industry
Stearic acid is used in skincare products such as vanishing cream and cold cream to emulsify, turning it into a stable white paste. Stearic acid is also the main raw material for the manufacture of almond honey and milk. Stearic acid soap esters are more widely used in the cosmetic industry.
