二叔丁基过氧化物分解产物的气相色谱法测定

Determination of Decomposition Products of Di t Butyl Peroxide by Gas Chromatography

采用气相色谱法考察了二叔丁基过氧化物分解温度与分解量之间的关系，研究了二叔丁基过氧化物分解产物的组成。实验发现：作为主要热分解产物的峰面积与二叔丁基过氧化物的量之间在２２．９１～１１４．９３μｇ范围内呈线性关系。测定未知浓度的过氧化物试样，有较好的精密度。

In this work we found that there were five decomposition products of di t butyl peroxide at 320℃ by GC MS. The peak area of acetone as a chief product in the thermal decomposition was related to di t butyl peroxide concentration in a linear manner. The range was from 22 91 to 114 93μg ( r =0 9997, n =4). By use of the calibration, we can possibly determine the content of the peroxide rapidly. The present method is more suitable for the determination of peroxide that is loable to decompos and difficultly to be vaporized.
