CN105859559A 一种3-乙氧基-4-硝基苯酚的生产方法 无效 - 驳回

一种3-乙氧基-4-硝基苯酚的生产方法
摘要：
本发明公开了一种3?乙氧基?4?硝基苯酚的生产方法，它采用价格低廉的间二氯苯替代高价格的间苯二酚为原料，并将甲氧基转化为羟基反应，采用简易的碱法，代替常规的溴化氢/醋酸体系，制备3?乙氧基?4?硝基苯酚。本发明采用价格低廉的间二氯苯替代高价格的间苯二酚为原料，制备3?乙氧基?4?硝基苯酚，其具有合成步骤简单、污染低绿色环保、产品质量高、收率高、生产成本低、常压操作、可工业化生产的优势。
摘要（英）：

The invention discloses a production method of 3-ethoxy-4-nitrophenol. The low-price m-dichlorobenzene is used instead of the high-price resorcinol as the raw material, and the methoxy is converted into the hydroxy; and a simple alkaline process is used instead of the conventional hydrogen bromide/acetic acid system to prepare the 3-ethoxy-4-nitrophenol. By using low-price m-dichlorobenzene instead of the high-price resorcinol as the raw material to prepare the 3-ethoxy-4-nitrophenol, the method has the advantages of simple synthesis steps, low pollution, environment friendliness, high product quality, high yield, low production cost and normal-pressure operation, and can implement industrial production.
