Product description:Refinement to light yellow crystals or needle crystal. Soluble in hot ethanol, ether and benzene, insoluble in water.Ethyl benzene with mixed acid nitration under 30-35 ℃ nitro ethylbenzene. After rectification of nitro ethylbenzene and adjacent nitro ethylbenzene al products. The nitro ethylbenzene in the presence of catalyst cobalt stearate, under pressure from 140-150 ℃, 0.2 MPa, nitrobenzene with air oxidation was ethyl ketone. The reaction products are washed, neutralization, centrifugal dehydration, drying, the finished product. Raw material consumption quota: ethylbenzene 2519 kg / 1535 kg/t t, nitric acid, sulfuric acid, hydrochloric acid 12 kg / 697 kg/t t t, caustic soda, soda ash, 81 kg / 111 kg/t t, methanol, ethanol, 100 kg / 100 kg/t.Organic synthesis intermediates, is to create sintomycin and chloramphenicol and other medical materials.
