【Abstract】 This paper presents a way to make m-dimetthylnitrobenzences from m-xylene with adiabatic nittrating method. Affecting factors, such as temperature, time, molar ratio, recycle use of the waste acid, etc. of the adiabatic nitration process are studied systematically, and better results are obtained. Both the yield and the purity of m-dimethylnitrobenzenes are higher than those obtained in usual nitrating method.更多还原
