摘要
介绍了用法国BEFS公司的PROABD蒽油一步结晶技术、减压蒸馏技术以及瑞士CIBA的蒽气相氧化技术,以蒽油或粗蒽为原料,生产蒽醌、咔唑等产品的工艺流程及主要设备,并对国内蒽醌的发展提出了几点建议。
The technology of PROABD anthracene oil one step crystallization,CIBA anthracene vacuum distillation gas-phase oxidation were introduced in this article.With anthracene oil or crude anthracene as raw materials, the technological processes and main equipment of anthraquinone,carbazole and other products were summarized. The development suggestions of anthraquinone was put forward in China.
