【摘要】 本文以N-羟甲基丙烯酰胺、氯乙醇、三甲胺为原料合成了N-2(丙烯酰胺甲氧基)乙基三甲基氯化铵,这是目前国内尚没有开发的一种新型季铵盐,其共聚或均聚体分别是性能良好的纸干强剂或絮凝剂。本文以P—B实验设计法较全面考察了反应温度、反应时间、反应物配料比、硫酸加入量、碳酸氢钠加入量等诸因素对合成反应的影响,初步确定了影响反应产品收率的关键参数及其各自的较佳值,建立了在一定范围内适用的数学模型。更多还原

【Abstract】 The paper relates to the synthesis of 2-（acrylamidomethyoxy） ethyl trimethyl ammonium chloride that is a new type of quaternary ammonium salt being not developed in our country, which provides better performance copolymers and homopolymers as dry strengthening agent for paper and flocculant, and it has been prepared from（N-hydroxymethyl） acrylamide, 2-chloroethanol and 33％ aqueous trimethylamine. In this paper, the influence of some factors, such as reaction temperature, reaction time, ratio of reactants and additive amours of H₂SO₄ and NaHCO₃, on synthetic reaction has been more overall inspected in the P-B experimantal design method, the key parameter influencing yield of the product and the better value of these parameters have been preliminary defined. The mathematical model within certain limits has been established.更多还原
