聚丙烯酸制备
以丙烯酸为单体在引发剂存在下进行聚合而得。
丙烯酸的制法
a.氰乙醇法 以氯乙醇为原料,与氰化钠瓜得氰乙醇。氰乙醇在硫酸存在的情况下于175℃水解得丙烯酸。
b.丙烯腈水解法 以丙烯腈为原料在硫酸存在下水解生成丙烯酰胺的硫酸盐,再水解得到丙烯酸。
c.雷佩法 与改良雷佩法 将乙炔溶于四氢呋喃中,计量后加入反应釜。在溴化镍和溴化铜组成的催化剂存在下通一氧化碳和水,在200~225℃下,7.8~9.8 MPa反应。
d.丙烯醛氧化法 将丙烯,空气,水按1︰10︰6 (V)的比例进行混合,然后通入第一沸腾床,在铝、钒、磷、铁、铝、镍、钾的催化下于370~390℃停留5.5s,线速度0.6m/s。然后进入第二沸腾床,在铝-钒=钨催化下,停留2.25s,反应温度控制在270~300℃。丙烯酸的空时收率为55~60 kg/m·h,这种方法安全,污染轻,成本低,是国内外生产的主要方法。
聚丙烯酸的制备 将去离子水加入聚合釜中,加热60~100℃,开始滴加过硫酸铵和丙烯酸的混合溶液(用去离子水配置)。滴毕后,继续保温搅拌3~4h。即得产品。将530kg去离子水加入聚合釜中,加入41kg平平加OS-15搅拌溶解。再加入4kg十二烷基硫酸钠,搅拌溶解后在20min内加入68kg混合单体(丙烯酸丁酯,丙烯腈)。搅拌15mi后加入1.5%的过硫酸铵水溶液30kg,30min内加完。继续搅拌15min后缓慢升温至70℃,开始滴加混合单体(272kg),大约1h滴完。加完后在80℃保温搅拌1h。
反应完毕后降温至40℃左右,加入70kg平平加OS-15,搅拌15min后过滤,除去杂质得产品
e.采用溶液聚合方法,以丙烯酸为原料,经水稀释后,在引发剂作用下聚合而成。丙烯酸聚合既快又放热,为实现对聚合过程的控制,用于循环水处理的聚丙烯酸制取中,通常把丙烯酸配成40%以下的水溶液进行聚合,聚合温度通常控制在50~150℃。常用引发剂为过硫酸铵和亚硫酸钠,在聚合过程中还常
加少量的 ( <5%)巯基琥珀酸、异丙醇等做缓聚剂,对苯二酚或邻苯二酚用作阻聚剂。将一定化学计量的去离子水加入到装有电动搅拌器、回流冷凝管、滴液漏斗和温度计的反应器中,开动搅拌并将反应温度升至80℃左右、将计量的巯基乙酸或异丙醇加入到反应器中与水混溶。将化学计量的过硫酸铵用计量的水配成稀溶液,置于聚合反应器上的滴液漏斗中,将计量的丙烯酸 (AA)单体与一定量水混合,置于聚合反应器上的另一滴液漏斗中。当反应器中的水温达到反应所需要的温度后,开始滴加丙烯酸单体水溶液和引发剂过硫酸铵水溶液,控制滴加速度使反应温度在85~90℃之间,聚合反应3~5H。反应完成后,将聚合液冷却至室温,取样分析各项技术指标,符合要求后分装。
