Electric Literature of 95-49-8, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 95-49-8 as follows.
A 100 mL four-necked flask was charged with 47 mL (50 g) o-chlorotoluene, 0.25 g [BMIM]Cl-2AlCl3 was added, The ionic liquid is stirred to disperse evenly. And then into the system 20 mL / min by concentrated sulfuric acid drying of chlorine, Reaction at 30 C for 12 h to give dichlorotoluene, The tail gas is removed by NaOH solution to remove unreacted Cl2.
According to the analysis of related databases, 95-49-8, the application of this compound in the production field has become more and more popular.
