| titleOfInvention | Method for producing bisphenol compound and method for producing polycarbonate resin |
| abstract | PROBLEM TO BE SOLVED: To provide a method for easily, efficiently and highly selectively producing a bisphenol compound exhibiting stable polymerization activity as a raw material for a polycarbonate resin on an industrial scale. SOLUTION: A method for producing a bisphenol compound represented by the formula (1) by reacting an aldehyde and a monophenol compound in the presence of a sulfonic acid compound represented by the formula (2). [R1 is a monovalent aliphatic hydrocarbon group of C6 to 24; R2 and R3 are independently monovalent hydrocarbon groups of C1 to 15; a and b are integers of 0 to 4; when a or b is 2 or more. , Two or more R2s or R3s on the same benzene ring may be bonded to each other to form a ring] [R4 is an n-valent hydrocarbon group of C1-20; n is an integer of 1-2] [ Selection diagram] None |
