Abstract
P-cresol first bromination to produce 2,6-dibromo-p-cresol(referred to as DMB),DMB and methanol and sodium in the reaction catalyzed by 2,6-dimethoxy-cresol(hereinafter referred to DMC),and then by vacuum distillation,acidification,extraction,filtration,washing and distillation process to extract product 2,6-dimethoxy-p-cresol,the yield≥98%,purity≥95%.
