    Dihydroresorcinol is obtained by subjecting solutions of resorcinol to catalytic hydrogenation in presence of at least one gram-equivalent weight of a strongly-basic compound per gram-molecular weight of resorcinol. Inorganic or organic bases or salts of strongly alkaline reaction may be used, but it is not necessary to use resorcinol also as a salt. The reaction may be carried out in aqueous or organic solvents at normal or higher pressure. According to examples, resorcinol is hydrogenated in with a nickel catalyst in presence of aqueous sodium hydroxide, methyl alcoholic sodium hydroxide, aqueous calcium oxide, alcoholic diethylamine, and with a palladium chloride catalyst in presence of aqueous sodium hydroxide followed by acidifying and extracting with ether. German Specification 77317 is referred to.ALSO:Dihydroresorcinol is obtained by subjecting solutions of resorcinol to catalytic hydrogenation in presence of at least one gram-equivalent weight of a strongly basic compound per grammolecular weight of resorcinol.
