Preparation of 5-tert-butyl-metaxylene using a solid active clay catalyst

Preparation of 5-tert-butyl-metaxylene using a solid active clay catalyst

Alkylation of metaxylene with isobutylene using a solid active clay catalyst produces 5-tert-butyl-metaxylene with high isomer selectivity with respect to 4-tert-butyl-metaxylene. The process is controlled to extend catalyst life and significantly reduce environmentally unfriendly waste.
