The chemical industry reduces the impact on the environment during synthesis 108-70-3, name is 1,3,5-Trichlorobenzene, I believe this compound will play a more active role in future production and life. 108-70-3
Example 4; Preparation method of 1,3,5-trifluorobenzene; 500 g of 1,3,5-trichlorobenzene, 1180 ml of sulpholane, 10.7 g of 3-nitrodimethylbenzamide and 640 g of dry KF were initially charged in an autoclave, then 48 g of CNC catalyst were added and the autoclave was sealed. The mixture was heated to 220 C. for 48 h. During the reaction, a maximum total pressure of 8 bar arose. Subsequently, the mixture was cooled to 20 C. The product was distilled off initially at standard pressure, later under reduced pressure. 310 g of a colourless liquid having a proportion of 87% by weight of 1,3,5-trifluorobenzene (74% of theory) and 8.8% by weight of difluorochlorobenzene (6.7% by weight of theory) were obtained. 1,3,5-Trifluorobenzene and difluorochlorobenzene can be separated distillatively in a known manner.
The chemical industry reduces the impact on the environment during synthesis 108-70-3. I believe this compound will play a more active role in future production and life.
