Lithium stearate is a white powdery compound with the chemical formula LiC18H35O2, also known as lithium octadecanoate and lithium octadecanoate.

White powder or colorless crystals. Density: 1.025 g/cm3. Melting point: 220.0-221.5°C. Stable under normal temperature and pressure. Slightly soluble in water and ethanol, the solubility in water is 0.09 g/100ml, and the solubility in ethanol is 0.04 g/100ml. It is decomposed into stearic acid and corresponding lithium salt in case of strong acid. Insoluble in ethyl acetate and mineral oil. It forms colloids in mineral oil.

Characteristics and synthesis method of lithium stearate

resolve resolution

Method 1: Dissolve 10g stearic acid in 100mL 95% ethanol and titrate with 0.5mol/L lithium hydroxide ethanol solution (if lithium hydroxide cannot be completely dissolved in ethanol, add water to make it completely dissolved), using phenolphthalein as an indicator. After the reaction reaches the equivalence point, the precipitated lithium stearate soap is separated by suction filtration. The crude product can be recrystallized with 95% ethanol to obtain a pure product.

Method 2: Dissolve sodium hydroxide in water to form a solution, add stearic acid, fully react, and heat to above 100°C. Lithium chloride is dissolved in water, cooled to room temperature, and added to the prepared sodium stearate solution for reaction; after the reaction, the material is discharged and centrifuged for dehydration; the finished product is dried by airflow drying equipment. To

Lithium stearate has good stability and reduces the overall cost of the enterprise. Mainly used as PVC heat stabilizer, suitable for transparent products. Its good performance can reduce the overall cost of the enterprise.

Lithium Stearate Application

Lithium stearate can be used as a polyvinyl chloride heat stabilizer for transparent products. When used in conjunction with phthalate plasticizers, the products will not produce white fog and the film has good transparency. Lithium stearate is easier to melt in ketones than other stearates, and paleontology has less influence on embossing operations. Lithium stearate can be used as a non-toxic substitute for barium soap and lead soap. Lithium stearate can also be used in conjunction with phosphatidic acid plasticizers. Lithium stearate can also be used as an external lubricant, suitable for nylon, phenolic resin, and rigid polyvinyl chloride (the maximum amount is 0.6 parts). In addition, lithium stearate is used to produce lithium-based grease in lubricating oil, which is waterproof and impermeable for construction. Wait.

Lithium nitride is the only stable alkali metal nitride

  Overview of Lithium Nitride  Li3N  Powder Lithium nitride is a metallic nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid, with a high melting point and a light green luster in reflected light and ruby color in transmitted light. Exposure to the air over a long period of time will eventually result in lithium carbonate. The chemistry of basic metal nitrides is extremely limited, and only lithium nitride is stable and easily prepared among binary compounds (sodium nitrite and potassium nitrite are prepared only under more extreme conditions). Lithium nitride belongs to the hexagonal crystal system. There are lithium and nitrogen layers composed of lithium and nitrogen atoms in lithium nitride crystal. The lithium atoms are arranged like carbon atoms in a graphite crystal, with nitrogen atoms at the center of a hexagon of lithium atoms. There is a lithium layer between the lithium and nitrogen layers.

  Overview of Cuprous oxide  Cu2O  Powder Cuprous oxide,   the chemical formula is Cu2O, is monovalent copper oxide, a bright red powder solid, almost insoluble in water, in acidic solution disproportionation into copper and copper elemental, in the wet air gradually oxidized into black copper oxide. Cuprous oxide is mainly used in the manufacture of ship bottom antifouling paint(used to kill lower Marine animals), insecticides, and various copper salts, analytical reagents, red glass, but also used in the preparation of copper plating and copper plating alloy solution. Copper(I)oxide is also known as an inorganic compound of copper oxide with the chemical formula Cu2O. It's essentially covalent. The copper(I)oxide crystallizes in a cubic structure. When heated, hydrogen tends to reduce the disproportionation it undergoes in acidic solutions that produce copper (II) ions and copper. When the copper oxide is gently heated with metal copper, it is converted to cuprous oxide. It acts

  Overview of Tungsten Disulfide Tungsten disulfide  as a potential battery material is also expected to benefit from more market replenishment. Tungsten disulfide is a layered material with remarkable surface effects, electron mobility, thermochemical stability and high electron density of states. It has been widely used for lithium and sodium storage. For example, nanocomposites as conductive additives or graphene composites as battery cathode materials can exhibit higher specific capacity and discharge efficiency, making up for the deficiencies of single-component WS2 or C as anode materials. The advent of sodium batteries is expected to alleviate the current shortage of lithium resources on the rapid development of the new energy industry, and will further stimulate the application of transition metal dichalcogenides such as tungsten disulfide WS2 in the field of power storage.  Lithium-ion batteries are a key raw material for developing energy devices and realizing the vision of &
