摘要
本文介绍了采用可见光分光光度法和紫外光分光光度法分别测定甲基丙烯酸酯类、丙烯酸酯类、醋酸乙烯酯和苯乙烯等不饱和单位中微量对苯二酚含量的方法。试验表明:这两种方法操作简捷,误差为±2%,准确性和重复性均好。
The determination of trace hydroquinone in unsaturated monomers such as methylacrylafe, acry late, vinyl-acetic ester and styrene by visible and ultraviolet spectrophotometric method was described in this paper. It was shown by the result that these methods were easy, accurate and repea table, the error was about ±2%.
