摘要
阳离子醚化剂环氧丙烷基-三甲基-铵盐OMTMA是制备阳离子改性类絮凝剂的关键反应物,OMTMA直接影响最终合成絮凝剂的絮凝效果。对阳离子醚化剂OMTMA制备的影响因素做了系列对比试验研究,确定了阳离子醚化剂OMTMA的最佳制备条件。最佳条件为:三甲胺与盐酸的物质的量比为2∶1、三甲胺与环氧氯丙烷的物质的量比为1∶0.8、反应温度40℃、反应时间2.5h。在此条件下,制备的阳离子醚化剂OMTMA对改性絮凝剂的合成具有良好的效果,絮凝去除率达到0.966。
Cationic etherifying agent OMTMA is a key reactant for preparing cationic flocculant ,which directly influenced the flocculation effect of final synthetic flocculant .The influence factors on the preparation of cationic etherifying agent OMTMA was studied ,and the optimal preparation conditions of cationic etherifying agent OMTMA is as follows ：molar ratio of amine hydrochloride to Trimethylamine 2∶1 ,molar ratio of trimethylamine to epichlorohydrin 1∶0 .8 ,reaction temperature 40 ℃ , reaction time 2 .5 h .OMTMA cationic etherification agent prepared is excellent on the synthesis of modified flocculant ,which has a removal rate of 96 .6% .
