Which expert knows the role of toluene in the production of diuron using phosgene and 3,4-dichloroaniline?
1. Solvent, does not participate in the reaction. 2. A cold reaction leads to the formation of salts, which acts as a diluent and improves the mixing effect. 3.……… That’s all I can think of for now; further details can be discussed.
Solvent. In phosgenation reactions, a solvent is generally used as a medium to enable the reactants to dissolve in each other; common solvents include benzene, toluene, chlorobenzene, o-dichlorobenzene, etc. First, it allows the reactants to dissolve in it; second, it dilutes the reactants and lowers the temperature of the reaction mixture, keeping it within a controllable range.
Could a small amount of phosgene be chlorinated onto toluene to form benzyl chloride?
The solvent, along with the material, can be recovered through drying, thereby saving costs
