100%和98%硫酸对酸性媒介黑T质量影响的对比研究

Comparing study on the affection of 100% and 98% Sulfuric acid in Synthesizing Eriochrome Black

研究了以100%和98%的硫酸为底酸的两种硝化工艺对合成酸性媒介黑T质量的影响.结果表明,采用100%硫酸为底酸比以98%硫酸为底酸合成的酸性媒介黑T的质量更好、收率更高.

This paper studies the effection of the nitration to synthesise Eriochrome Black under 100% suffuric acid and 98% acid. It states clearly that the quality is better and the yield is higher under 100% sulfuric acid then 98% acid.
