SULFONATED BIS(PHENYLSULFONYL)-1,1-BIPHENYL COMPOUND CAPABLE OF LOCATING MULTI-SUBSTITUTED SULFONATE GROUP ON A SITE LESS ACTIVATED THAN AN ORTHO SITE OF A POLYMER BACKBONE, AND CONTROLLING SULFONATION DEGREE, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A sulfonated bis(phenylsulfonyl)-1,1-biphenyl compound is provided to manufacture a sulfonated bis(phenylsulfonyl)-1,1-biphenyl compound capable of using for manufacturing a polymer by nucleophilic aromatic substitution polymerization.;CONSTITUTION: A manufacturing method of a sulfonated bis(phenylsulfonyl)-1,1-biphenyl compound in chemical formula 1 comprises a step of reacting a compound in chemical formula 2 with fuming sulfuric acid, chloride sulfonic acid, or sulfuric acid, and a step of substitution-reacting the reaction product with alkaline metal solution. In chemical formula 1, four aromatic rings respectively has 0-1 of SO3M on site of 3,3' or 2,2', in here M is -H, -Li, -Na, -K, -Rb, -Cs or -Fr, and R is -H or halogen-substituted a C1-50 alkyl group, a C6-50 aryl group, and a C1-50 alkyl group, and is located on site of 3,3' or 2,2'.;COPYRIGHT KIPO 2012
