【Abstract】 The new process for manufacturing anthracene products with a combined pro- cess is studied. The anthracene with purity of 99. l4%, phenanthrene with purity of 96. 28% and carbazole with purity of 96. 88% can be produced simultaneously. The process is character- ized by simple production process, low investment, no environmental pollution and so on.更多还原
