摘要
顺丁烯二酸酐是一种重要的有机原料,对其含量的测定有很大意义。目前,文献上提到的顺丁烯二酸酐含量测定方法的误差较大。因此,研究了各种条件下测定顺丁烯二酸酐的含量。实验结果表明:用纯水、40%DMF水溶液或40%丙酮水溶液做溶剂时,都能够较准确测定顺丁烯二酸酐的含量,在有机体系中用40%丙酮水溶液较纯水或40%DMF水溶液好。
Maleic anhydride is a important organic raw, the research of determination the content of it has practical meanings. the way that determination the content of maleie anhydride has been reported is not accurate. Therefore,determinatlon the content of maleie anhydride in different conditions is rescerched. The results show that the content of maleie anhydride can be accurately determined by using pure water, 40 % acetone dissolved in water or 40 % DMF dissolved in water as solvent. And 40 % acetone dissolved in water is better in organic system.
