Product Description

2-Chlorophenol CAS no 95-57-8

Production method: 

1, (1) from sodium chloride by chlorination, acidification derived. Stir the mixture of sodium phenol, water and ice, slowly add sodium hypochlorite solution below 20 ℃, control the temperature below 20 ℃, room temperature overnight, stirring under the concentrated hydrochloric acid to pH 2, washed once, and then 5% carbonic acid Sodium solution to the wash solution pH 4-5, after cooling, separate the oil layer, the normal pressure fractionation, and then by distillation under pressure derived products.

(2) chlorination of phenol with chlorine. The molten phenol was added to benzene under stirring, and chlorine gas was introduced at 26 ± 2 ° C until the relative density of the chlorination solution reached 0.954 (23-25 ° C). After removal of hydrogen chloride, the benzene was distilled off and evaporated to 125 ° C (21.3 kPa). The mixture was cooled to 60 ° C and fractionated under reduced pressure. The fraction was collected at 75 ° C (2.67-3.33 kPa) to give o-chlorophenol. Chlorination reaction also produces p-chlorophenol and 2,4-dichlorophenol, in the decompression fractionation as a high boiling material collection, the separation can be used as a by-product. O-chlorophenol (95%) yield of nearly 50%, p-chlorophenol (95%) yield of about 25.5%.

2, o-chlorophenol is the production of p-chlorophenol products, chlorinated with phenol is the ortho and para-chlorophenol, the separation can be obtained p-chlorophenol and o-chlorophenol.

O-chlorophenol is colorless to yellow brown liquid, m.p. 8.7 ℃, 175 ℃, b.p. n25D 1.5565, relative density 1.265, this product is slightly soluble in water, soluble in ethanol, ethyl ether and alkali solution. Used in medicine, pesticide, and dye and other organic synthetic raw material.

Product expansion

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.
