1. Electrolysis Bromine and potassium hydroxide by the synthesis of potassium bromide dissolved in distilled water dubbed the electrolyte, electrolysis 24h after the first batch of crude, after every 12h once to take the crude product was washed with water to remove potassium bromide with distilled water Dissolved, add a small amount of potassium hydroxide to adjust pH to 8, insulation 0.
After 5 h, the filtrate was filtered and the filtrate was cooled to room temperature in a crystallizer. Crystallization, separation and drying gave the potassium bromate product. The reaction equation is as follows: anode cathode
2. Chlorination Oxidation of milk and bromine after the reaction of chlorine chlorine oxidation reaction until the pH value of 6 to 7 termination of the reaction. After deslagging, the filtrate is evaporated. Adding barium chloride solution to react to form barium bromate precipitate, filtering the precipitated suspension in water, maintaining a certain temperature and adding potassium carbonate for metathesis reaction, the crude potassium bromate is washed with a small amount of distilled water for several times, filtered, evaporated, cooled and crystallized, separated and dried , Crushed, obtained food potassium bromate products. The reaction equation is as follows: …
For analysis reagents, oxidants, food additives, wool bleaching agent.
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.
