摘要
丙烯酸树脂用乙酸丁酯溶解,采用毛细管气相色谱法分离树脂中的残余单体及溶剂,然后用内标法及氢火焰离子化检测器(FID)测定各残余单体的含量。该方法分离效果好,灵敏度高,操作简单,准确可靠。
The acrylic rein is dissolved in butyl acetate and residual monomer and solvent in resin are separated by capillary gas chromatography. Internal standard method and FID are used to determine the content of the residual monomer in resin. The methods ale of good separating effect, simple operation and accurate.
