论文部分内容阅读
编辑同志: 你刊2卷7期中发表的‘利用废酸液水解乙醯磺胺噻唑’一文提供了生产技术上的经验,诚然有它一定的价值;不过该文中所报告的数据有些颇不可靠,今提出与作者及读者商榷: 一、关於废酸含量的问题: 该文是用290克的氯磺酸与67.5克的退热冰进
Editing comrades: The article “Using Waste Acids to Hydrolyze Acetyl Sulfathiazole” published in Volume 2 of Volume 7 provides technical experience. It is true that it has certain value; however, the data reported in this paper is somewhat unreliable. This issue is addressed to the author and reader: 1. The question of spent acid content: This article uses 290 grams of chlorosulfonic acid and 67.5 grams of antipyretic ice.
