| Abstract: | The synthesis of tetrachlorophthalic (TCPA) was studied by catalytic chlorination of phthalic anhydride (PAA) in the medium of chlorosulfonic acid using iron and iodine as catalyst. Qualitative analysis of chloroproducts and its relative percentage of chloroproducts during different chlorination reaction stages (monochlorophthalic anhydride, dichlorophthalic anhydride, trichlorophthalic anhydride and isomerides) was analysed by means of GCMS. Optimum process condition for promoting of product yield was found. |
