Catalytic wet oxidation of high-concentration p-chlorophenyl isocyanate wastewater;

Study on catalyst of catalytic wet oxidation of high-concentration p-chlorophenyl isocyanate production wastewater;

During the synthesis of N,N′-bis(4-chlorophenyl)urea by hydrolysis of p-chlorophenyl isocyanate,at first,p-chlorophenyl isocyanate was dissolved in acetone,then water was added dropwise with constant stirring.
