【摘要】 采用气相色谱法测定对甲基苯磺酰异氰酸酯,按峰面积归一化法计算含量,稳定性试验表明,对甲基苯磺酰异氰酸酯在高温、氧气环境下稳定,而在光、潮湿环境下极不稳定,样品应在干燥、密闭、避光和充氮气条件下贮存。更多还原

【Abstract】 Gas chromatographic method was used for the determination of p-methyl benzenesulfonyl isocyanate(MBSIC),the content was calculated by the method of normalized peak area.Experimental results showed that MBSIC was stable in atmosphere of oxygen and under high temperature,but unstable to light irradiation and moisture.Sample of MBSIC should be stored in dry and closed container filled with nitrogen and placed in dark place.更多还原
