摘　　要：研究了聚乙烯甲酰胺 ( PNVF)碱性水解反应动力学 ,碱的消耗量与氨基生成量的关系 .实验结果表明 :氨基生成量与 Na OH消耗量物质量的比是 2∶ 1 .聚乙烯甲酰胺碱性水解反应速率与聚乙烯甲酰胺、氢氧化钠浓度分别呈一级关系 ,该反应的表观活化能是 65 .1 6k J· mol- 1 .The relation between sodium hydroxide consumption and Polyvinylmine(PVAm) generation and the kinetics of basic hydrolysis of PNVF were investigated.The results indicate that the stoichiometric ratio of sodium hydroxide and PNVF was 1∶2. The reaction was of first order with respect to both PNVF concentration and sodium hydroxide concentration. The activation energy of the reaction was 65.16 kJ·mol -1.
