What is Lithium stearate? Lithium stearate is a white powdery compound with the chemical formula LiC18H35O2 and CAS registration number 4485-12-5. White powder or colorless crystal. Density:1.025g/cm 3. Melting point: 220.0-221.5℃.Lithium stearate is officially classified as soap (a salt of fatty acids). Lithium stearate is a soft white solid prepared by the reaction of lithium hydroxide with stearic acid.
Lithium stearate solubility: slightly soluble in water, and ethanol, the water solubility is 0.09 g/ 100mL, and ethanol solubility is 0.04 g/100ml. Decomposition into stearic acid and corresponding lithium salts in response to strong acid. Insoluble in ethyl acetate and mineral oil. Colloids form in mineral oils. Production technology of Lithium stearate powder Method 1: Dissolve 10g stearic acid in 100ml of 95% ethanol, titrate with 0.5mol/L lithium hydroxide ethanol solution (if lithium hydroxide can't be completely dissolved in ethanol, add water to make it completely soluble), using phenolphthalein as indicator, and filter out the precipitated lithium stearate soap after the reaction reaches the equivalent point. The crude product can be recrystallized with 95% ethanol to obtain the pure product. Method 2: Dissolve sodium hydroxide in water to form a solution, add stearic acid to it, then fully react and heat to above 100℃. Dissolving lithium chloride in water, cooling it to normal temperature, and adding it into the prepared sodium stearate solution for reaction; Discharging after the reaction is finished and dehydrating by a centrifuge; Drying by air-flow drying equipment to obtain the finished product. Uses of Lithium stearate powder 1. Lithium stearate can be used as a heat stabilizer for transparent PVC products. When used together with phthalate plasticizers, the film of this product has good transparency and does not produce a white mist. 2. Lithium stearate is easier to melt in ketone than another lithium stearate, so it has less influence on embossing operations. Non-toxic, barium soap, lead soap substitute. The product can also be used together with a phosphatic acid plasticizer. 3. The product can also be used as an external lubricant for nylon, phenolic resin, and hard PVC (the maximum dosage is 0.6%). In addition, the product can also be used for building waterproofing and seepage control. Used for lithium stearate grease. Price of Lithium stearate powder Lithium stearate powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Lithium stearate powder. A large amount of large amount will be lower. The price of Lithium stearate powder can be found on our company's official website. Lithium stearate powder supplier Luoyang Tongrun Nano Technology Co.
