| Abstract: | The thesis briefly introduces the application,characters and synthetic speciality of 4,4'-Dichloromethyl-biphenyl(BCMB).It summarizes the technology of synthesis and post treatment,using paraformaldehyde and biphenyl as raw material,zinc chloride to catalyzer,through chloromethylation.According to the characteristics of catalyzer and relative theory,it has a key analysis of catalyzer,the theory of catalyzing and its attention point,and has a discussion on the relation between the temperature and the time of reaction,besides the post treatment and removing dichloromethyl ether.At the end,it has a good suggestion on the research of BCMB synthesis in the future. |
