Method for producing bisphenols |
| abstract |
PROBLEM TO BE SOLVED: To provide a process for producing bisphenols (I) which has a fast reaction, a high yield and does not require recovery of a diluting solvent. A reaction solvent selected from dialkylphenols (II) and trioxanes (III) selected from an aliphatic hydrocarbon solvent having 6 to 10 carbon atoms and an aromatic hydrocarbon solvent having 6 to 12 carbon atoms, an anionic system The reaction is carried out in the presence of a surfactant as well as an acid catalyst. (I) (II) (III) [Wherein, R 1 represents a hydrogen atom and an alkyl group having 1 to 4 carbon atoms, and R 2 and R 3 each independently represents an alkyl group having 1 to 5 carbon atoms. ] [Selection figure] None |
