摘　　要：文章介绍了一种改性C.I.分散黄241的合成方法,该方法包含N-甲基-4-甲基-6-羟基-2-吡啶酮的合成和改性分散黄241的合成两个步骤。考察了硫酸的用量、反应时间和反应温度对N-甲基-4-甲基-6-羟基-2-吡啶酮的合成实验的影响,重点研究了N-甲基-4-甲基-6-羟基-2-吡啶酮的合成的后处理,探索出一种较合理的实验方法,提高了第一步N-甲基-4-甲基-6-羟基-2-吡啶酮的利用率,降低了废水中的COD。合成的改性分散黄241与现有产品分散黄241相比,产品的耐pH值变色性能有明显提高。In this paper,a synthetic method of modified C.I.dispersed yellow 241 was introduced.The method consisted of two steps:synthesis of N-methyl-4-methyl-6-hydroxy-2-pyridinone and synthesis of modified dispersed yellow 241.Looked at the amount of sulfuric acid,reaction time and reaction temperature on the N-methyl-4-methyl-6-hydroxy-2-pyridine ketone of synthetic experiment,the influence of the research is mainly focused on the N-methyl-4-methyl-6-hydroxy-2-pyridine ketone synthesis of post-processing,explore a more reasonable experimental method,improved the first step in N-methyl-4-methyl-6-hydroxy-2-pyridine ketone utilization,reduce the waste water COD.Compared with the existing dispersed yellow 241,the modified dispersion yellow 241 has better pH resistance.
