The catalysis of resinic solid acid catalysts in catalytic distillation is studied for synthesis of methylal from methanol and formaldehyde. 考察了树脂型固体酸催化剂对甲缩醛合成反应的催化性能,并与传统的硫酸催化剂进行了比较。
When the resinic demulsifiers is are synthesized using solvent polymerization, it is found that the dosages of butyl acrylate ( BA), methacrylic acid ( MAA) and initiating agent ( AIBN) in demulsifiers all exist optimum values; 评价溶液聚合方法合成的树脂型破乳剂的破乳效果,得出破乳剂组分中丙烯酸丁酯(BA)、甲基丙烯酸(MAA)和引发剂(AIBN)用量都存在最佳值;
