2—甲基蒽醌新工艺研制

2-Methyl Anthraquinone beMade from New Technology

2—甲基蒽醌新工艺研制,省去了原间接操作法中的三道工序——酸析、过滤、干燥,转为直接操作法。其优点是:生产工序简单,能耗低,废水废酸量少,并能减少设备投资,降低产品成本,提高经济效益。

2—methyl anthraquinone be made from new technology. Three working procedure be omited from indirect operate—acid out;filter;dried. the direct operate has changed. The advantages is what the production procedure simple;the energy consumption low;the waste water waste acid measure low ,and the equipment invest is reduced', the products costs is reduced, the economy benefit is improved.
