6月24日,由山东谦诚工贸科技有限公司自主研发的吡啶双定向合成法制备3,5,6-三氯-2-吡啶酚钠(简称三氯吡啶酚钠)清洁生产新工艺,在山东青州通过了中国石油和化学工业联合会组织的科技成果鉴定。新工艺单位产品能耗为0.15吨标煤,仅为传统工艺的1/4。此外,传统工艺每生产1吨三氯吡啶酚钠产生20吨废水,新工艺实现了水
On June 24, a new process for the clean production of sodium 3,5,6-trichloro-2-pyridinol (abbreviated as trichloropyridinophenol sodium) was prepared by the bi-directional pyridine synthesis method independently developed by Shandong Qiancheng Industry and Trade Technology Co., Qingzhou in Shandong adopted by the China Petroleum and Chemical Industry Federation organized the identification of scientific and technological achievements. The new unit of energy consumption per unit of product 0.15 tons of standard coal, only 1/4 of the traditional process. In addition, the traditional process produces 1 ton of sodium trichloropyridine phenols to produce 20 tons of waste water, the new technology to achieve water
