  • Patent number: 5210330
    Abstract: Disclosed is an improved process for the preparation of phenylhydroquinone wherein hydroquinone is first alkylated with cyclohexene to produce cyclohexylhydroquinone which is then dehydrogenated to obtain phenylhydroquinone. The improvement comprises carrying out both the alkylation and dehydrogenation reactions in the presence of a solvent comprising diphenyl ether, biphenyl or a mixture thereof. The solvent possesses selective solubility for hydroquinone and cyclohexylhydroquinone which permits the separation of unreacted hydroquinone from the alkylation reaction product. The boiling point of the solvent also permits the dehydrogenation reaction to be performed at substantially atmospheric pressure.
