H. Grabowska et al., CONTINUOUS ALKYLATION OF 5-METHOXY-1-NAPHTHOL AND 4-METHYL-1-NAPHTHOLWITH ALCOHOLS OVER AN IRON CATALYST, Applied catalysis. A, General, 144(1-2), 1996, pp. 1-5
The vapour phase alkylation of 5-methoxy-1-naphthol and 4-methyl-1-nap
hthol with alcohols in the presence of an iron catalysts (magnetite) t
hat contained Cr-, Si- and K oxides was investigated, At temperatures
of 580-655 K alkylderivatives with high yield in ortho-position to the
hydroxyl group were obtained. The reactions were carried out in an co
ntinuous process at atmospheric pressure.
