Secondly, the silver based catalysts modified by phosphorus, zirconium, zinc, potassium and so on using molecular sieve as carrier, which were produced by ion-exchange method, had also good catalytic performance for 1,2-propane glycol oxidation to methylglyoxal. The conversion of 1,2-propane glycol and the selectivity of methylglyoxal were both high, and the impurity such as formaldehyde and acetaldehyde in the product is little. At the condition of the temperature 300 ℃, the molar ratio of oxygen to 1,2-propane glycol 1.7:1, the space velocity 6000h~(-1), and the concentration of 1,2-propane glycol 70wt%, the conversion of 1,2-propane glycol is 90% and the selectivity of methylglyoxal is 45% on the Ag-P catalyst.
其次对采用离子交换法制备的负载在分子筛上的银系催化剂进行了研究,发现此催化剂在助催化剂磷、锆、锌、钾等的作用下对丙二醇的低温氧化脱氢具有很高的活性,可以得到较好的丙酮醛的收率,并且产物中的甲醛、乙醛副产物的量比较低;经过对Ag-P催化剂上反应条件的考察,发现当温度为300℃、氧醇比1.7:1、空速6000h~(-1)、丙二醇浓度为70wt%时,丙二醇的转化率为90%,丙酮醛的选择性为45%。

The same methods were used to study toluene dinitration, and the results indicated that the thermal runaway risks of these reactions were low too; prolonging dosing duration was helpful to the conversion of all nitrotoluene; decreasing the molar ratio of nitric acid to mononitrotoluene would make an insufficient conversion; among the given temperatures, rising reaction temperature couldn\'t markedly change the yield coefficient, but lead more heat generation and higher thermal runaway risk.
采用同样的方法对二段硝化反应进行研究,结果表明:二段硝化反应的热失控危险性也较低;延长加料时间,有利于反应完全;而随着硝酸与一硝基甲苯摩尔比的减小,硝化难以进行完全;在选定温度范围内升高温度,产物得率无显著变化,反而易导致放热加剧,增加体系的热失控危险。
