Several kinds of cationic exchange resin were evaluated in terms of catalyzing the reaction of methanol and maleic anhydride to produce dimethyl maleate in a fixed-bed reactor.
在固定床反应器上对顺酐与甲醇反应生成顺丁烯二酸二甲酯的催化剂进行了筛选。
The selectivity of dimethyl maleate was up to 90% based on a complete conversion of maleic anhydride.
顺丁烯二酸酐完全转化时,二甲酯产物选择性达到90%。
Taking methanol and maleic anhydride as feed, several catalysts were tested under a given condition to determine the best one according to the selectivity of dimethyl maleate.
在强酸性阳离子交换树脂催化剂的作用下,以甲醇与顺丁烯二酸酐为原料进行催化蒸馏合成顺丁烯二酸二甲酯的研究。
