A differential infrared method is described for the quantitative determination of ethoxy group in silicone oil by using the characteristic absorption of the ethoxy group at the band of 960 cm-1. The sensitivity of this method is about 0.1% and its accuracy is 0.015%. 应用乙氧基在960厘米~（-1）处的吸收,建立了硅油中乙氧基的红外光谱定量测定方法,方法的灵敏度为0.1％,精确度为0.015％。 硅油中苯基含量可以应用紫外光谱法测定,精确度为0.53％,也可以由其中硅元素含量测得,两种方法所得结果无显著差异。应用紫外光谱法同时可以定量测定两种不同类型结构及在甲基苯基硅油中的相对含量。 Procedures for the preparation of β-cyanvethyl methyl silicone oil are described, and the properties of such oil of 4 different compositions are tabulated. 本文报导根据作者所作实验,制备β-氰乙基甲基硅油的具体操作及四种成分的这种硅氰油的性能。 A gas chromatographic method, which utilizes a glycerol column connected in series with a silicone oil column, has been developed for the analysis of liquid phase byproducts in butadiene synthesis from ethanol. Ethanol and water, the main components, are separated from the other components by back-flushing through the glycerol column. Further resolution of the components free from water and ethanol is carried out on silicone oil column. By means of the functional group colour reaction, treated the vapour sample... A gas chromatographic method, which utilizes a glycerol column connected in series with a silicone oil column, has been developed for the analysis of liquid phase byproducts in butadiene synthesis from ethanol. Ethanol and water, the main components, are separated from the other components by back-flushing through the glycerol column. Further resolution of the components free from water and ethanol is carried out on silicone oil column. By means of the functional group colour reaction, treated the vapour sample with chemical reagents in syringe, and the addition of supposed constituents, six compounds, i.e., acetaldehyde, ethyl ether, acetone, valeraldehyde, butyraldehyde, and ethyl acetate have been identified, and the former four constituents are quantitatively estimated by the absolute peak height method. 进行了用甘油柱和硅油柱串联以分离乙醇合成丁二烯液相产物中的副产物的研究.首先在甘油柱中将样品内大量乙醇和水同其他组分分离,井用反吹法将乙醇和水冲出柱外,其他组分进入硅油柱进一步被分离.通过颜色反应、化学处理和假设组分三种方法,鉴定出副产物中含有乙醛、乙醚、丙酮、戊醛、丁醛和乙酸乙酯等化合物;对前四种物质还进行了定量分析.
