1-Chloro-2-methyl-4-nitrobenzene Use and Manufacturing
Take 152kg of 2-amino-5-nitrotoluene, dissolve it in 600kg of concentrated sulfuric acid, add 150kg of water, and naturally heat up to100 ° C, After all the 2-amino-5-nitrotoluene is dissolved, the temperature is lowered to 0 ° C.Adding 300 kg of industrial hydrochloric acid with a mass concentration of 30percent, keeping the temperature of the reaction solution not exceeding 0 ° C during the addition, adding 276 kg of 25percent sodium nitrite solution at a constant rate to obtain a diazonium salt solution;Adding 450 kg of industrial hydrochloric acid to another reactor, 225 kg of cuprous chloride was dissolved under stirring, and the temperature was lowered to below 20 ° C after dissolution. The diazonium salt solution was quickly added to the reaction vessel for rapid stirring and hydrolysis. After 2 hours of heat preservation, the temperature was raised to 55 ° C and the temperature was kept for 2 hours.The temperature was raised and the water vapor was distilled off to 160 kg of 2-chloro-5-nitrotoluene, and the yield was 93.3percent.
