The Methods of Lowering the Content of Free Sulfuric Acid in TetrabromopHthalic Anhydride 降低阻燃剂四溴苯酐中游离硫酸的方法研究
The results showed that the thermal decomposition of tetrabromophthalic anhydride proceeded in two stages. 结果表明:四溴苯酐的热分解过程分两步进行。
Study on a new method of synthesis for tetrabromophthalic anhydride 四溴苯酐合成新方法研究
It is found that the catalytic activity of this new catalyst is consistent with that of the general catalysts such as iodine and iodine-iron, and is suitable for the synthesis of tetrabromophthalic anhydride. 该催化剂的催化效果和常用的碘、碘-铁催化剂相同,适用于四溴邻苯二甲酸酐的合成。
Thermograrimetry-differential analysis was used to the study of the thermal decomposition dynamics of tetrabromophthalic anhydride. 用热重&差热分析法对阻燃剂四溴苯酐的热分解过程进行了动力学研究。
