Abstract:
Liquid-phase alkylation of p-tert-butylphenol (TBP) and p-cresol by olefins and benzyl chloride in the presence of solid heteropoly acids (HPA) H3PW12O40 and 25% H3PW12O40/SiO2 at 100–150°C provides high yields of mono- and disubstituted products. HPAs are more active than H2SO4, easily separated from the reaction mixture and can be used repeatedly.
Алкилирование пара-трет-бутилфенола (ТВФ) и пара-крезола олефинами и бензихлоридом в жидкой фазе в присутствии твердых гетерополикислот (ГПК) H3PW12O40 и 25% H3PW12O40/SiO2 при 100–150°C дает с высоким выходом моно- и ди-замещенные продукты. ГПК активнее, чем H2SO4, легко отделяются от реакционной массы и могут быть использованы повторно.
