METHOD OF PRODUCING 2,6-DIISOBORNYL-4-METHYLPHENOL |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of producing 2,6-diisobornyl-4-methylphenol which is widely used in different industries as an antioxidant, as well as an initial component in synthesis of surfactants and fragrance compounds. The method involves alkylation of p-cresol with camphene while heating in the presence of a catalyst. Alkylation is carried out while heating to 20-180C and with molar ratio of p-cresol to camphene equal to 1:2. The catalyst used is an aluminium-containing compound taken in amount of 0.5-100 wt % aluminium to the mass of the initial phenol. ^ EFFECT: method enables to obtain an end product with high selectivity and output. ^ 5 cl, 1 tbl, 9 ex |
