三论氧气法制二苯胍

The Third Discussion on the Preparation of Diphenyl-guanidine by Oxygen Oxidizing

《论氧气法制二苯胍》① 一文导出了氧气法制二苯胍的化学反应过程 ;《再论氧气法制二苯胍》② 一文揭示了氧气法制二苯胍化学反应的成键原理及成键过程。在此基础上 ,本文讨论和纠正氧气法制二苯胍现行技术文献中引用的化学反应存在的问题 ;同时 ,还发现了生成副产物硫代硫酸铵的化学反应 。

In the first thesis 'On Making Diphenyl-guanidine process by oxygen oxidizing' the writer demonstrated the chemical reactions of making diphenyl-guanidine process by oxygen oxidizing, in the second thesis the writer described the bonding theory and process in the chemical reaction of making diphenyl-guanidine process by oxygen oxidizing and based on what is revealed in the above aiticles. in this thesis the writer discussesd and corrected the remaining problems of chemical reactions in the existing technical documents regarding making diphenyl-guanidine process by oxygen oxidizing. At the sametime it is found out that the chemical reactions that produce the accessory outcome of ammonium thiosulfate and the status and development of ammonium thiosulfate.
