Alkylation of hydroxyarenes with alcohols in the presence of iron catalyst

Wrzyszcz J., Grabowska H.

Polish Journal of Chemical Technology

1999

Vol. 1, nr 1

50-52

The efficient catalytic method of alkylation of some hydroxyarenes with alcohols by a gas phase continuous process in the presence of iron catalyst modified with silicon, chromium and potassium oxides is presented. The catalyst displays high activity and stability. The alkyl group enters the ortho position of the hydroxyl group. The high yields obtained and selectivities of alkyl derivatives of hydroxyarenes make their separation and purification easy.
