2-Chlorophenol CAS no 95-57-8
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.
