摘要
研究了碱种类及其浓度Ｍａ、对硝基甲苯邻磺酸浓度ＭＮＴＳ对氧气液相氧化对硝基甲苯邻磺酸（ＮＴＳ）制取４，４’－二硝基二苯乙烯－２，２’－二碳酸（ＤＮＳ）的影响。发现在水介质中以模拟酶为催化剂、Ｍ_ａ＝１．０Ｍｏｌ／Ｌ、Ｍ_(ＮＴＳ)＝０．３８Ｍｏｌ／Ｌ于ｄ控温温度６０℃下反应１８ｈ，可以获得８１．８％的粗品收率，其纯度用高效液相色谱（外标法）测定可达９６．７％。ＤＮＳ的结构通过核磁共振谱得以确认。
Fffect of the sort of alkaline and its concentration Ma, the concentration of p-nitro-o-sulfonic acid (MNTS) on preparation of 4, 4-dinitrostilbene-2, 2'-disul fonic acid by means of oxygen oxidation of p-nitrotoluene-o-silfonic acid in liquidphase was investigated. The research results showed that oxygen liquid-phase oxidation of p-nitrotoluene-o-stlfonic acid by choosing Simulated enzyme as catalysts, Ma = 1mol/L, and MNTS=0.38mol/L in water solution at 60℃ for 18h could give 4, 4-dini- trostilbene-2, 2-disulfonic acid in 81.8% yield and in 96.7% purity which was delermined with HPLC. The structure of DNS was confirmed by H-NMR
