DADMAC as a cationic monomer by homopolymerization or copolymerization to form polymers. The polymer can be used as superior non-formaldehyde fixing agent in textile dyeing and finishing auxiliaries to form a film on the fabric to improve the color fastness. It can be used as retention and drainage aid in papermaking auxiliaries, and paper anti-static ; Can be used for decolorization, flocculation and purification in water treatment, efficient and non-toxic; in household chemicals, can be used for shampoo combing agent, wetting agent and antistatic agent; available in oilfield chemicals In the flocculant, plugging agent. Its main role is neutralization, adsorption, flocculation, purification, decolorization, especially as a synthetic resin modifier, given the conductivity, antistatic properties.
The 40% aqueous solution of dimethylamine 330kg was added to a reaction kettle with a circulating cooling water system, cooled to below 20 ℃, and then slowly added sodium hydroxide solution 125kg, until the sodium hydroxide solution was added, cooled to 10 ℃ or less. Then from the allyl chloride feed tank slowly add allyl chloride 492kg, when allyl chloride was added to the amount of 1/3, the system temperature was raised to 15 ℃; when allyl chloride was added to 2/3 When the system temperature is 20 ℃. Add the remaining allyl chloride below 25 ° C until the addition of allyl chloride, the system was warmed to 45 ° C, at this temperature reflux for 6 ~ 8h. After the reaction time has been reached, the resulting reaction product is cooled to below 15 ° C, and the resulting sodium chloride is removed by filtration. The filtrate is transferred to a still pot and concentrated under reduced pressure. After concentration to a certain extent, hot filtered to remove by-produced chlorine Sodium. In the resulting filtrate by adding a certain amount of distilled water to control the solids content of more than 60%, the material, packaging, that was polymerization grade dimethyl diallyl ammonium chloride solution.

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.
