light yellow crystals. It is insoluble in water (only 0. 03% at 25 ℃), slightly soluble in cold ethanol, soluble in hot ethanol, ether, acetone and benzene and other organic solvents. The relative density was 1. 2979. Melting point 83.5 °c, boiling point 242 °c. The flash point of pure product was 127 ℃. Decomposition temperature 300. Flammable.
after nitric acid and sulfuric acid were mixed into mixed acid, nitration reaction was carried out with chlorobenzene to produce nitrochlorobenzene (para 65%, Ortho 34%, Meta 1%), and then nitrochlorobenzene and waste acid were separated. After separation, the nitrochlorobenzene was washed with water and neutralized to obtain neutral nitrochlorobenzene, which was then dried and crystallized. The product P-nitrochlorobenzene was separated, and the co-dissolved oil was subjected to rectification, de-coking and crystallization to obtain the product O-nitrochlorobenzene.
preparation of dyes (azo dyes, sulfur dyes), medicine (phenacetin, paracetamol), pesticides (herbicide) important intermediates, can also be used as raw materials of rubber antioxidant 4010.
