What is lithium stearate used for?
What is lithium stearate used for?
As a general-purpose lubricating grease, lithium stearate is also used as a stabilizer in the cosmetic industry as well as the plastic one. Due to its properties, this compound also has applications as a corrosion inhibitor in petroleum.
How is lithium stearate made?
Lithium stearate is a chemical compound with the formula LiO2C(CH2)16CH3. It is formally classified as a soap (a salt of a fatty acid). Lithium stearate is a white soft solid, prepared by the reaction of lithium hydroxide and stearic acid.
Is lithium soap grease the same as lithium grease?
Lithium soap is a soap consisting of a lithium salt of a fatty acid. Sodium-based and potassium-based soaps are used as cleaning agents in domestic and industrial applications, whereas lithium soaps are used as components of lithium grease (white lithium).
What happens when LiOH is heated?
22.3. It loses crystalline water to form anhydride LiOH almost over 423 K (150 °C) by heating and then it melts at 735 K (462 °C), which is higher than the melting temperature of NaOH or KOH. However, only LiOH decomposes to oxide (Li2O) and H2O by further heating differently from other alkaline hydroxides.
Is LiOH a strong or weak base?
Is LiOH an acid or base? Lithium hydroxide (LiOH) is the base since it releases OH– ions on dissolving in an aqueous solution. LiOH is the strong base because it completely dissociates in an aqueous solution and produces a large number of OH– ions.
What kind of soap is lithium 12 hydroxystearate?
Lithium 12-hydroxystearate is a fatty acid salt commonly known as a “lithium soap”. It is the most common soap used to stabilize and thicken lubricating greases.
What kind of grease is made of lithium?
Lithium 12-hydroxystearate is widely used in lubricants, stabilizers, bleaching agents, thickeners. Size:-200 Mesh. Lithium grease is made by thickening mineral oil with Lithium 12-Hydroxystearate soap and adding oxygen, rust, corrosion, and other extreme pressure antiwear additives.
What is the formula for lithium 12 hydroxystearate?
Lithium 12-hydroxystearate fast facts CAS Reg. No. 7620-77-1 Empirical formula C 18 H 35 LiO 3 Molar mass 306.42 g/mol Appearance White crystals or powder Melting point 200–220 ºC
What kind of oil is used for lithium hydroxystearate?
For applications, lithium 12-hydroxystearate is usually dispersed in synthetic oils such as silicone oil and ester oil. The synthetic oils are preferred for their greater stability and ability to perform at extreme temperatures. The 12-hydroxystearic acid is prepared by the hydrogenation of castor oil.
