PURPOSE: To obtain a strongly acidic sulfonic acid type ion exchange resin catalyst having a high rate of conversion of acetone and used for producing bisphenol A by an economically advantageous condensation reaction of acetone with phenol by ionic-bonding N-methyl-N-3-mercaptopropylpyrrolidium. CONSTITUTION: N-methyl-N-3-mercaptopropylpyrrolidium is ionic-bonded to a strongly acidic ion exchange resin made of a sulfonated styrene-divinylbenzene copolymer by 5-40mol% of the amt. of all sulfonic acid groups of the ion exchange resin. When the resultant ion exchange resin is used, bisphenol A can be efficiently produced by a condensation reaction of phenol with acetone at a high rate of conversion of acetone. |
