甲基氯硅烷混合单体过去是应用化学分析(氯含量分析)和比重分析测定的。为了更有效的配合车间生产以及提供操作数据,目前,我厂应用102气相色谱仪对甲基硅橡胶、甲基硅油和甲基硅树脂的原料——甲基氯硅烷混合单体进行气相色谱分析。分析结果表明,该法具有速度快,精确度高,操作简单等优点。现将操作过程和分析步骤简述如下。 (一)被分析的样品来源和主要物理常数甲基氯硅烷是以硅粉和氯甲烷为原料,以氯化亚铜还原生成的铜粉为催化剂、锌粉为助
Methylchlorosilane mixed monomer used in the past by chemical analysis (chlorine content analysis) and gravimetric determination. In order to more effectively meet the workshop production and provide operational data, at present, I plant the application of 102 gas chromatograph of methyl silicone rubber, methyl silicone oil and methyl silicone raw materials - methyl chlorosilane monomer mixture for gas chromatography . The analysis results show that the method has the advantages of fast speed, high precision and simple operation. Now the operation of the process and analysis of the steps outlined below. (A) the source of the sample to be analyzed and the main physical constants Methylchlorosilane is silicon powder and methyl chloride as raw materials, cupric oxide produced by the reduction of cuprous chloride as a catalyst, zinc powder to help
