“引言”由于“十一五”期间,国内氯碱企业规模增长迅速,生产、运营模式的简单复制呈现出显著特点,导致行业在高速增长过后中,必将面临着产业布局不合理、低端产品产能结构过剩等一系列影响行业可持续发展的内生性根本问题。“十二五”发展重点明确指出:加强自主创新,推动行业技术进步,尤其是不断开发高附加值的耗碱、耗氯产品。而我国作为氯碱行业的大国,发展耗氯产品有极其重要的作用。通过对耗氯下游产品的深入了解及调研,合理开发具有市场竞争力的耗氯产品也将成为企业发展新时期的重要课题,作为耗氯产品的三氯乙烯和四氯乙烯是C2有机氯溶剂,在金属脱脂剂、金属 “Introduction ” During the “Eleventh Five-Year Plan” period, the scale of chlor-alkali enterprises in China increased rapidly and the simple reproduction of production and operation modes showed distinctive characteristics. As a result, after the rapid growth of the industry, the industrial layout was bound to be unreasonable , Low-end products, excess capacity structure and a series of endanger the sustainable development of the industry’s fundamental problem. “Twelve-Five ” focus of development clearly pointed out: to strengthen independent innovation and promote technological progress in the industry, in particular, continue to develop high value-added alkali consumption, chlorine consumption products. As a big country in the chlor-alkali industry, China has an extremely important role in developing chlorine-consuming products. Through in-depth understanding and investigation of the downstream products of chlorine consumption, rational development of market-competitive chlorine-consuming products will also become an important issue in the new period of enterprise development. Trichlorethylene and tetrachlorethylene, which are chlorine-consuming products, are C2-chlorinated solvents In metal degreaser, metal
