| 摘 要： | 邻苯二甲酸混合酯的定性分析是一项较困难的工作，主要问题在于酯基中的碳数为一种分布或几种不同碳数的混合体，如采用通常的分离测定很难实现的。利用红外光谱法，通过红外吸收强度差值来测定邻苯二甲酸混合酯中单酯基的平均碳数。并利用此法，测得某厂进口增塑剂邻苯二甲酸混合酸的平均碳数为１４，得到了一个较满意的结果

| Abstract: | It is diffcult to determinate mixture ester phthalate qualitatively , and the problem is that the carbon number of mixture ester phthalate is a mixture of several carbon numbers or in a distrbution. It is not available to determinate average carbon number by separation. In this paper, the good result was obtained to determine average carbon number in monester alkyl of mixture ester phthalate by the difference of infrared absorption intensity. Average carbon number of 14 in monester alkyl in a chemical plants plasticizer has been obtained by this method. |

| Keywords: | Diester phthalate Plasticizer Difference of infrared absorption intensity |
