气相色谱法测定树脂中微量硝基苯

Gas Chromatographic Determination of Trace Nitrobenzene in Resin

此项工作的提出,是因为在合成711树脂即聚砜树脂时用硝基苯作溶剂。尽管用沉淀法进行分离,但在树脂中还会包含有少量硝基苯。此树脂加工成型温度高达340℃。在加工过程中硝基苯挥发会造成空气污染。

This essay is about the determination of trace nitrobenzene in high polymer by OC. To achieve the aim of quantitative analysis,the high polymer is made up into solution and the pyrolyzer is used to put into the sample.
