Uses and synthesis of Stearic acid powder

Stearic acid powder, CAS [57-11-4], is a white or yellowish white solid, soluble in alcohol and acetone, Stearic acid CAS 57-11-4 is easily soluble in ether, chloroform, benzene, carbon tetrachloride, carbon disulfide, amyl acetate and toluene, etc., Stearic Acid Raw Materials Melting Point 69.6 Stearic acid Raw Materials Melting Point 69.6°C, is one of the main components of oil.

Applications / Functions of Stearic acid powder

Stearic acid powder is widely used as cold-resistant plasticiser, stabiliser, surfactant, release agent, rubber vulcanisation accelerator, etc. It is also widely used in the manufacture of plastics.

Stearic acid CAS 57-11-4 Used as the vulcanising active agent of natural rubber, synthetic rubber (except butyl rubber) and latex, also used as the raw material of plastic plasticiser and stabiliser.

It is also used as raw material of plasticiser and stabiliser. It is used in medicine to prepare ointment and suppository, etc. Stearic acid Raw Materials is also used in the manufacture of cosmetics, candles, waterproofing agent and polishing agent.

• Stearic acid Raw Materials is used as lubricant, defoamer and raw material of food additives such as glycerol stearate, sorbitan stearate and sucrose ester in food industry.
• Stearic acid powder can be used as a standard for gas phase analysis, and is also used in the preparation of soaps, cosmetics, pharmaceuticals and other organic chemicals.
• Stearic acid CAS 57-11-4 can be used for the determination of water hardness.

Physicochemical Property of Stearic acid powder

Stearic acid powder is white soft flakes with gloss. Slightly soluble in cold water, soluble in alcohol, acetone, soluble in benzene, chloroform, ether, carbon tetrachloride, carbon disulfide, amyl acetate and toluene.

Production methodprocess of Stearic acid powder

1. Pressing method takes animal oil as raw material, hydrolysed in the presence of zinc oxide under the pressure of 1.17~1.47MPa, and then obtained Stearic acid powder after acid washing, water washing, distillation, cooling, solidification, pressing to remove oleic acid.
2. Cotton seed oil, rice bran oil or soybean oil in the presence of hydrolysis agent at atmospheric pressure heating to boiling, hydrolysis 1.5h, hardening to saturated fatty acids.
3. Hydrogenation with oleic acid.
4. With synthetic fatty acids C10 ~ C20 and C18 ~ C20 fractions as raw materials by melting, pickling (with 1% sulfuric acid) casting, pressing, melting, pickling, dehydration and crystallisation of Stearic acid CAS 57-11-4 .
