Abstract
A process for the manufacture of resorcinol is described which relies upon the intermediacy of a .alpha.,.beta.-unsaturated ketone which can be reacted with a hydroxy moiety-containing compound to obtain a resorcinol precursor which is subsequently converted to resorcinol. In a specific embodiment, 2-cyclohexenone is reacted with water to obtain 3-hydroxycyclohexanone which is dehydrogenated to resorcinol. In another embodiment, 2-cyclohexenone is oxidized to cyclohexane-1,3-dione which is dehydragenated obtain resorcinol.
