本文介绍了高压聚乙烯新型催化剂——引发剂K的主要原料异壬酸的气相色谱分析法。在无标样条件下,采用双柱定性法,按有效碳数近似规律计算相对重量校正因子,比较满意地解决了由异壬醇碱熔制异壬酸的定性和定量分析。本方法简便,有普遍的适用意义。 This article describes the new high-pressure polyethylene catalyst - initiator K isoniazole the main raw material for gas chromatography. Under the condition of no standard sample, the double-column qualitative method was used to calculate the relative weight correction factor according to the approximate law of effective carbon number. The qualitative and quantitative analysis of isononanoic alcohol melting isononanoic acid was satisfactorily solved. This method is simple and has a universal meaning.
