降低阻燃剂四溴苯酐中游离硫酸的方法研究
The Methods of Lowering the Content of Free Sulfuric Acid in TetrabromopHthalic Anhydride
【摘要】 通过剖析四溴苯酐中游离硫酸形成原因,对原有的生产工艺进行优化改进,合成得到了熔点高、游离硫酸含量低的四溴苯酐。
【Abstract】 The free sulfuric acid content more than 0.1% in tetrabromopHthalic anhydride will influence the properties of the downstream products.This paper analysis the cause of free sulfuric acid in tetrabromopHthalic anhydride,by optimizing and improving the production technology,the tetrabromophthalic anhydride was obtained withhigh melting point and low free sulfuric acid content.
