The present invention relates to a group of resorcinol derivatives as a pharmaceutically active compounds and methods of preparation thereof. Resorcinol derivatives have been used to treat various diseases and disorders. While such treatments hold promise, there remains a need in the art for more effective treatments and this has been brought about by way of the resorcinol derivative of the invention.

Provided are a bisphenol represented by the general formula (1), a method for producing the bisphenol, and a polyarylate resin, a (meth)acrylate compound and an epoxy resin which are derived from the bisphenol. In the formula (1), R.sub.1 to R.sub.4 are the same or different, and each represent an alkyl group, an aryl group or a halogen atom, n.sub.1 and n.sub.2 are the same or different, and each represent an integer of 1 to 4, and k.sub.1 to k.sub.4 are the same or different, and each represent 0 or an integer of 1 to 4. When at least one of k.sub.1 to k.sub.4 is 2 or more, corresponding R.sub.1 to R.sub.4 may be the same or different.

Processes for producing cresol from an alkylphenol stream involve transalkylating the longer-chain alkylphenols (i.e., having an alkyl chain with 2 or more carbon atoms) with an aromatic solvent such as benzene and/or toluene in a first transalky lation reaction zone to obtain phenol, cresol, xylenol, trimethylphenol, and alkylbenzenes. The xylenols and trimethylphenols are reacted with phenol in a second transalkylation reactor to obtain the desired cresols. Xylenes can also be produced.
