摘要
Abstract
To achieve mass production of Janus Green B and fill the domestic gap in the field of industry produc?tion, we designed two synthetic routes for Janus Green B through analogy. N, N-diethyl-1, 4-phenylenediamine, or p-phenylenediamine(containing N, N-diethylaniline) was subjected to cyclization reaction with aniline to obtain 3RAX in the presence of potassium dichromate, then Janus Green B was prepared after diazotization and coupling reaction. The total yields of Janus Green B obtained are 29.5% and 24.9%, respectively. At the same time, the pilot technological procedure of Janus Green B was designed, and the technological process and process diagram with control points were drawn up. Meanwhile a preliminary approach was proposed for treat?ing process wastewater containing chromium, which lays the foundation for the implementation of the industrial?ization process.关键词
