| Abstract: | This new process, with full use of coal, the commonest resource in nature, is non-toxic, safe, low-cost and low energy-consumptive, and therefore holds an important place in the dye production.The article dealing with the conditions of the key reaction(Hfmann oxidation rearrangement) in the process, has offered an optimum technology and experimental reason for raising the productivity and benefit of the manufacture. |
