(57) [Summary] (Problem corrected) [Problem] To have an s-butyl group or a phenyl group or a C6-16 long-chain alkenyl group in a phenol skeleton for a raw material for producing asymmetric alkylidene bisphenols or alkylidene polyhydric phenols. A novel alkenylphenol or a mixture of isomers thereof is provided. The alkenylphenols of the general formula I. (R 1 is s-butyl or phenyl group, R 2 is methyl group, Tertiary alkyl group of ethyl or C4~13, R 3 represents a hydrogen or a methyl group. However, when R 2 is a methyl group, R 3 Is hydrogen, and when R 2 is an ethyl group, R 3 is a methyl group. A) a mixture of both isomers of the general formulas IIIa and IIIb. (R ′ is hydrogen or an alkyl group, R ″ is an alkyl group, provided that the total number of carbon atoms of R ′ and R ″ is 3 to 12. R ′ ″ represents hydrogen or a methyl group.) (R ', R "and R'" are the same as above.) |
