ａ -氰基苯甲肟是合成辛硫磷的重要中间体 ,目前国内各生产厂家多数采用化学法分析 ,分析结果偏高 ,不利于生产。我们通过实验 ,用高效液相色谱法对其进行定量分析 ,条件适宜 ,分析准确 ,可适用于车间生产。1 实验部分1 .1 仪器与试剂美国光谱物理公司ＳＰ881 0 ;Ｐ1 0 0紫外
A - Cyanobenzyl oxime is an important intermediate for the synthesis of phoxim. At present, most manufacturers in China use chemical analysis, which results in high analytical results and is not good for production. We through the experiment, using high performance liquid chromatography for quantitative analysis of its conditions, the analysis is accurate, suitable for workshop production. 1 Experimental Section 1.1 Instruments and Reagents American Spectroscopic Physics Corporation SP881 0; P1 0 0 UV
