高碳醇生产过程中的增链是用四氯化钛作催化剂,使乙烯与一氯二乙基铝、二氯一乙基铝反应,在常压、中温下进行调聚的工艺,其介质有一定的腐蚀性。增链反应釜采用3毫米厚1Cr18Ni9Ti钢板卷焊而成的容器。运转十几天,就产生裂纹,介质从裂纹中渗漏出来。加料波纹软管也是1cr18Ni9Ti制,累计物料流经时间仅二小时,就穿孔渗漏。 The chain extension in the high-carbon alcohol production process is a process of using titanium tetrachloride as a catalyst to make ethylene react with diethylaluminum dichloride and aluminum monochloride and carry out telomerization under normal pressure and medium temperature. The medium A certain degree of corrosion. Chain reactor using 3 mm thick 1Cr18Ni9Ti steel plate welded into the container. Running a dozen days, it produces cracks, medium leakage from the cracks. Corrugated hose is also 1cr18Ni9Ti system, the cumulative material flow through the time of only two hours to puncture leakage.
