1. Toluene continuous photo-chlorination method to dry iron-free toluene added to the iron-free reactor, under high temperature chlorination. Then fractionated chlorinated products, namely, benzyl chloride, hydrogen chloride by-product hydrogen chloride was absorbed by the water, byproduct α-dichloromethyl benzene can be made by the hydrolysis of benzaldehyde.
Toluene without photothermal chlorination Toluene first 6h to remove more than iron, and then by the high tank into the chlorination pot to steam heated to stop boiling after boiling, chlorine gas through chlorination, continuous reaction system The obtained benzyl chloride is cooled into the storage tank through the bottom overflow pipe. The preparation of benzyl chloride is mainly derived from the chlorination of toluene. At present, there are mainly two methods at home and abroad: photochlorination and photothermal chlorination. Points from the process operation, the two methods have their own intermittent operation and continuous operation of two. From the reactor structure to points, continuous operation can be divided into horizontal continuous operation and vertical continuous operation of two. Due to the continuous light chlorination of toluene with a small batch production easy to launch, the reaction rate faster than the non-photothermal chlorination advantages, more domestic manufacturers to adopt this technology. Generally use small horizontal series continuous reactor group. The dry non-ferrous toluene was added to the glass bottle chlorinated, heated to 110 ℃, the liquid slowly boiled, according to chlorine and toluene mass ratio of 1: 2.5 in the fluorescent lamp through the chlorine, at 110 ~ 120 ℃ High temperature chlorination reaction to the end. Unreacted distillation recovery of toluene, collecting 160 ~ 180 ° C is the crude benzyl chloride. And then often pressure distillation, collecting 176 ~ 182 ° C distillate, that is, benzyl chloride products. Toluene photothermal chlorination generally use a large vertical continuous enamel reactor. In addition, toluene in the presence of catalyst peroxide and sulfurous chloride reaction, or zinc chloride in the benzene ring chloromethylation, can be prepared benzyl chloride.
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.
