production method
1.Inhalation of α-chloropropene into a bromination tank by addition of α-chloropropene and hydrogen bromide, adding a small amount of benzoyl peroxide, and then passing hydrogen bromide into the bottom of the tank, the reaction temperature is controlled at 18°C The endpoint is when the relative density reaches 1.5 or more. The product is washed with water and alkali washed (2% sodium hydroxide), and then washed with water. The aqueous layer is divided and dehydrated with anhydrous calcium chloride for 24 hours. The pressure is divided into fractions of 130° C. and the low boilers are separated and then distilled under reduced pressure. , Collection of fractions above 70°C (21.3 kPa) results in finished products. The hydrogen bromide used in the production is produced by adding hydrobromic acid to sodium bromide, raising the temperature to 60° C., dropping sulfuric acid, keeping the reaction at 80-90° C. to release hydrogen bromide gas.
2. Method: Add newly fractionated 3-chloropropene to the reaction flask
(2) 38g (0.5mol) was cooled in an ice water bath and irradiated with a low-pressure ultraviolet lamp. The hydrogen bromide gas equivalent to 1.1-1.2 times the amount of 3-chloropropylene was gradually introduced, and it was completed after about 2-8 hours. The reaction solution was washed three times with water, 3% sodium bicarbonate, and washed with water until neutral. Anhydrous calcium chloride was dried overnight, then fractionated under reduced pressure, the low boilers were distilled off first, and then the fractions of 68-69°C/7.9 kPa were collected to obtain 1,3-bromochloropropane…

use
Used as a pharmaceutical intermediate, mainly for the synthesis of products such as chlorpromazine, trifluoperazine, perphenazine, clomipramine, phentolamine, doxepin hydrochloride, and Teldon.

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 uut 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.
