对硝基苯乙酮中和残液的再利用研究

The Reuse of Neutralization Residue in Production P-nitroacetophenone

本文研究了采用活性炭吸附—稀硫酸中和法处理对硝基苯乙酮中和残液,从而得到精对硝基苯甲酸及其影响因素。

A method of absorption by carboraffin and neutralization by diluted sulfuric acid to treat the neutralization residue in production of P-nitroacetophenone was studied. The yield of P-nitrobenzoic acid and the influence factors were discussed.
