摘要
系统地研究了邻二氯苯混酸绝热硝化的 DVS值、混酸组成及摩尔比等因素对 2 ,3-二氯硝基苯收率的影响 .2 ,3-二氯硝基苯收率达到1 4.51 % ,3,4-二氯硝基苯与 2 ,3-二氯硝基苯的收率之比 f ( 3,4/2 ,3) =5.
The preparation of 2,3 dichloronitrobenzene from O dichlorobenzene Via mixed acids adiabatic nitration is studied. The influences of factors, such as the molar ratio of reactions, DVS and the composition of mixed acids etc on the yield of 2,3 dichloronitrobenzene is investigated systematically. The yield of 2,3 dichloronitrobenzene comes up to 14 51%, f (3,4/2,3) =5 47. This value is higher than the best one of the literature.
