一、前言在利用二氟氯甲烷热裂解制备四氟乙烯的过程中,会生成一些毒性较大的付产物,对这类付产物进行鑑定及解毒,一直是大家非常关心的问題,这次我们七·二一大学学员在实验厂实习期间,在党总支及支部的关怀下,在工人师傅的热情帮助下,对这一问題又进一步作了一些研究。二、实验部分 1.一氯七氟丁烯的鉴定: 将高沸点残液进行分馏,分出20—47℃的馏份,此馏份中含有多种烯烃,使在紫外光照下加
I. INTRODUCTION In the process of preparing tetrafluoroethylene by thermal decomposition of difluorochloromethane, some toxic products will be formed. Identification and detoxification of such products have always been of great concern to everyone. This time we During the internship at the experimental plant during the internship in the experimental plant, the students of the National Day and the 21st under the care of the party general branch and the branch and with the help of the workers’ masters, made some further research on this issue. Second, the experimental part 1. Identification of chlorinated heptafluorobutene: The high-boiling residue fractionation, 20-47 ° C fractionation, this fraction contains a variety of olefins, the addition of UV light plus
