二甲基甲酰胺(dirnethylformamide下面简称DMF)主要用作萃取乙炔、制造腈纶、合成皮革及染料、制药等工业。它可以以蒸气形式扩散,从呼吸道吸入体内,高浓度可以引起中毒。近期我市新区某皮革厂,由于车间空气中DMF超标,而致使三人发生急性肝炎的事件。对二甲基甲酰胺进行检测,文献报道所用色谱柱较特别,一时无法制备,我们探索用毛细管柱进行检测,建立了检测方法,取得了满意的结果。1 实验部分1.1 仪器与试剂 GC-14A气相色谱仪(FID检测器)、CR4A数 Dirnethylformamide (hereinafter referred to as DMF) is mainly used for extraction of acetylene, acrylic, synthetic leather and dyes, pharmaceutical and other industries. It can spread as a vapor, inhaled from the respiratory tract, and high concentrations can cause poisoning. Recently a new tanneries in our city, due to excessive DMF in the air workshop, which led to three cases of acute hepatitis. For dimethylformamide detection, the literature reported the use of special columns, sometimes unable to prepare, we explore the use of capillary column for detection, the establishment of a detection method, and achieved satisfactory results. 1 Experimental 1.1 Instruments and reagents GC-14A gas chromatograph (FID detector), CR4A number
