Abstract

Methyl naphthyl carbinol is obtained by acting upon a mixture comprising methyl naphthyl carbinol and methyl naphthyl ketone in the liquid state with hydrogen in the presence of a hydrogenation catalyst at a reactive temperature below that at which substantial dehydration of methyl naphthyl carbinol occurs. A copper chromite catalyst is preferred, the hydrogenation being then effected at a preferred temperature range of 100 DEG to 125 DEG C. Other hydrogenating catalysts such as nickel and nickel alloy catalysts may be used. The mixture comprising methyl naphthyl carbinol and methyl naphthyl ketone may be obtained by oxidizing ethyl naphthalene as disclosed in Specification 626,313 of which the present Specification is a division and the hydrogenation is effected in the same way and described with reference to the same flow-diagram as is shown and described for the hydrogenating step in the said Specification.
