本文介绍了一种改进的丙烯酸树脂中残留单体的提取方法，并用气相色谱法测定残留单体的浓度。根据其物理化学性质选择的四种有机溶剂（甲醇，N，N-二甲基甲酰胺，乙酸乙酯和甲乙酮）进行了测试，以确定其在不同温度和时间段下提取残留单体的能力。发现在4 ℃下用甲乙酮萃取是最有效的。该方法比迄今为止报道的其他方法更简单有效，因此似乎适合于临床实验室使用。
An improved method of extraction of residual monomer from acrylic resin has been described for determination of the concentration of residual monomer by gas chromatography. Four kinds of organic solvent selected according to their physicochemical properties (methanol, N,N-dimethylformamide, ethyl acetate and methyl ethyl ketone) were tested for their capacity to extract residual monomer at varying temperatures and time periods. Extraction with methyl ethyl ketone at 4 degrees C was found to be the most effective. The method is simpler and more effective than others reported so far, and therefore seems to be suitable for clinical laboratory use.
