The main application of lithium dodecyl stearate

Overview of Lithium Lauryl Stearate

Lithium lauryl stearate is a chemical substance with the molecular formula CH3(CH2)5CH(OH)(CH2)10COOH.

Molecular weight: 300.4806 Properties flaky or needle-like crystals. Melting point 74-76 °C (lit.). Flammable and low toxicity. Insoluble in water, soluble in ethanol, ether and chloroform.

Lithium lauryl stearate is widely used in lubricants, stabilizers, decolorizers and thickeners. It is used in the manufacture of lubricating grease, and also used in organic synthesis to prepare anti-rust lubricating grease, lithium-based lubricating oil, surface active substances, etc. It can also be used as a chemical intermediate.

Preparation method: in the presence of nickel-aluminum catalyst, hydrogenated castor oil is saponified and acid hydrolyzed at 185 ° C and 5 MPa to obtain the product.

Application of Lithium Lauryl Stearate

Lithium lauryl stearate is a white powdery industrial product. It can be prepared by direct reaction between 12-hydroxystearic acid and equimolar lithium hydroxide. It can also be used to formulate various greases. Versatile, for lubrication. Stable and stable medium. It can also be used to prepare anti-rust greases, such as lithium-based lubricants.

Lithium composite technology at home and abroad has achieved rapid development in my country in the 1990s. Industrial production is mainly composed of lithium salt-containing C9-C10 dibasic acid, boric acid or salicylic acid, and 12-hydroxystearate lithium complex, any of them two-component or three-component composite production of grease. Lithium 12-hydroxystearate, lithium azelaate or lithium sebacate, lithium borate and lithium salicylate are added to the base oil. The two-step saponification process is used to control the temperature and time of the one-step complex saponification, the two-step alkali addition temperature, the complex co-crystallization temperature and time, and the maximum temperature control. Leakage, high temperature bearing life, excellent comprehensive performance, can meet the high temperature environment equipment lubrication and high temperature centralized pumping lubrication. The complex lithium-based grease of the present invention belongs to high-temperature grease, and its dropping point is not lower than 260°C. Its outstanding advantages are good adhesion, excellent high temperature leakage resistance, and outstanding bearing life at 160°C. Compared with polyurea grease, it has the advantage of not hardening at high temperature. Compared with ordinary binary or ternary lithium complexes, it has the advantages of adhesion, excellent high temperature anti-leakage performance, and outstanding high temperature bearing life. It can meet the high temperature environment equipment lubrication and high temperature centralized pumping lubrication.

Lithium-based greases are prepared by saponification with special high-acid-value mineral base oils. Put the high acid value mineral base oil into the kettle, add 12-hydroxystearate lithium soap and lithium stearate soap, stir and heat; when the temperature rises to 210~220℃, keep stirring for 1~5min; put the base oil Put the material into the kettle to quickly cool down the material, add additives when the temperature reaches 140-150℃; stir evenly and discharge it out of the kettle; and obtain the finished product after grinding by three-roll mill. The lubricating grease of the invention rationally utilizes the existing domestic base oil resources, replaces the raw material of naphthenic acid, and greatly reduces the production cost of the lubricating grease. The lubricating grease of the invention not only has good mechanical stability and colloidal stability, but also can effectively improve the friction and wear conditions during the operation of mechanical equipment, and has good lubricating performance. Grease can be used for the lubrication of mechanical equipment such as automobiles and construction machinery.
