ABSTRACT:
Organic compound mixtures enriched in meta-isopropylphenol are prepared by alkylating phenol with isopropanol or propylene to form mixtures of isopropylphenol isomers and by subsequently selectively cracking the para-isopropylphenol isomer from such a mixture over a ZSM-5 type cracking catalyst. Concentration of the para-isomer is thereby selectively reduced relative to the meta-isomer and the meta-isopropylphenol isomer can be further separated from the remaining mixture by fractionation procedures.
