Composition containing bisphenol, production method for same, production method for bisphenol a, and production method for polycarbonate resin

Abstract

Provided is a bisphenol (I)-containing composition that can give an improved recovery rate of isopropenylphenol when the composition is subjected to an alkaline degradation and recombination process. A bisphenol (I)-containing composition includes: a bisphenol (I) comprising bisphenol A; and a compound (II) having a structure in which at least one hydroxyl group of a bisphenol is replaced with a carbonate ester group or a carbamoyloxy group, wherein the content of the bisphenol (I) in the bisphenol (I)-containing composition is 90% by mass or more; and the total number of moles of carbonyl bonds in the compound (II) relative to the mass of the bisphenol (I)-containing composition is 0.05 μmol/g or more.
