摘　　要：丙烯酸的结构决定了丙烯酸非常容易聚合,因此在生产过程中,常通过加入阻聚剂以防止丙烯酸的聚合,而在使用前又需要去除阻聚剂。本文介绍了常用的几种类型阻聚剂,并对其机理和性质进行了分析,进而对如何去除阻聚剂进行了探讨。最后,本课题组提出了一种去除阻聚剂的方法,即非金属组合物吸附去除法,该方法可取代传统的阻聚剂去除方法,有一定的借鉴意义。Acrylic acid can often self-polymerize for its special structure.Some polymerization inhibitors are often added in to prohibit the self-polymerization.But before being used,the polymerization must be removed.The mechanisms of several polymerization inhibitors were analyzed and the removal methods were studied.In addition,a new method was provided for removing polymerization inhibitors,which could replace the old-fashioned ways,and had a certain reference significance.
