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 results indicated isoprene was soon consumed under the condition of excess ozone. During the reaction, the major carbonyl products formed were methyl vinyl ketone, methacrolein, methylglyoxal, and formaldehyde. Formic acid, CO and CO2 were also among the products.

在反应温度(294±2)K，压力为1.01×10^5Pa空气，O3过量的条件下，异戊二烯很快反应完全，反应中生成的羰基产物主要包括甲基丙烯醛、甲基乙烯基酮、丙酮醛和甲醛；产物中还包括甲酸、一氧化碳和二氧化碳。

The results showed that the optimum preparation conditions of moulding materials were as follows: moler ratio of melamine to formaldehyde 1:2.5, water turbidity of the reaction end point 1:3, content of cellulose 42%~48%, fineness of moulding powder 100~120 mesh.
