1. Preparation of sodium stearate solution Stearic acid was dissolved in 20 times (mass) of hot water, adding a content of 1074kg / m3 (10 ° Bé) caustic soda solution at about 75 ℃ for saponification reaction to produce dilute Sodium stearate solution.
2. Synthesis of Calcium Stearate Calcium chloride solution having a content of 1074 kg / m3 (10 ° Bé) was added to the sodium stearate solution prepared as described above and the metathesis reaction was carried out at about 65 ° C. The product calcium stearate Precipitation precipitation. Then filtered, washed, dried at about 90 ℃, that is the finished product.
3. Suspend 5.60 g (0.1 mol) of calcium oxide in 300 mL of hot water at 55 ° C. Then chemically pure 51.3 g of stearic acid was dissolved in 350 mL of hot water at 70 ° C, 0.75 g of diethanolamine was further added, and the mixture was emulsified by stirring. The stearic acid emulsion has been made within 2h gradually added to the calcium oxide suspension, and stirred well, the formation of white insoluble matter that calcium stearate filtered, and dried to give the product.
Uses: heat stabilizer for PVC and a variety of plastic processing lubricants, release agents. In hard products, with salt-based lead salt, lead soap with gelation can improve the speed. Also used in food packaging, medical equipment and other non-toxic soft film and apparatus. Can also be made of polyethylene, polypropylene halogen absorber to eliminate residual catalyst on the color and stability of the adverse effects. As a plasticizer in rubber processing, can make natural rubber and whole rubber soften, but almost no effect on vulcanization. Also used as polyolefin fiber and molding compound lubricant, grease thickener, textile waterproofing agent, paint flatting agent, plastic disc when making plasticizer. Also used in the production of the pencil lead and medicine, spices industry. Calcium stearate.
1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.
2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.
3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.
4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.
5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
