寻求内容:采用有机芳香磺酸钠盐和烧碱为原料,要求提供加热“热熔态”化学反应过程的工艺、设备技术、自动控制设施,有机芳香磺酸工序阶段收率90％,连续运转能力1000T/日以上。 寻求解决双甲苯酚的生产工艺 寻求内容:1.日前产品中对甲苯酚对应含量仅91％左右,且邻位和间位无法有效控制,要求解决工艺问题,使产品对应含量达99％以上。2.目前废水中含酚太高,需引进废水处理技术和装置,提取废水中的酚,使废水达到0.5PPM排放标准。
Seeking content: Using organic aromatic sulfonic acid sodium salt and caustic soda as raw materials, it is required to provide technology, equipment technology and automatic control facilities for heating “hot-melt” chemical reaction process, and the process yield of organic aromatic sulfonic acid is 90%, continuous operation ability. 1000T/day or more. Seeking to solve the production process of bis-cresol Seeking content: 1. The relative content of p-cresol in the product is only about 91%, and the ortho and meta-positions cannot be controlled effectively. It is required to solve the process problem and make the product corresponding to more than 99%. 2. At present, the phenol content in the wastewater is too high. Wastewater treatment technology and equipment must be introduced to extract the phenol from the wastewater, so that the wastewater can meet the 0.5PPM emission standard.
