Application

2,2 ‘- di (2-chlorophenyl) -4,4’5,5’ – tetraphenyl-1,2 ‘- diimidazole is a photoinitiator called o-chlorohexaaryldiimidazole (BCIM). The current synthesis method uses sodium hypochlorite as the oxidative condensing agent for BCIM, which brings a lot of alkaline “wastewater” and has low yield and high cost.
