Abstract: A continuous process for the production of diacetate derivatives of aromatic compounds, comprising feeding at any convenient temperature an oxygen-containing gas and feedstock comprising a diisopropyl ring substituted aromatic compound and the recycled monoisopropyl-monoacetate derivative thereof, to an oxidizer operated, for example, at from about 10.degree. C. to about 150.degree. C. and oxygen partial pressures of from about 0.05 to 10 atmospheres to form an oxidizer product comprising the mono- and dihydroperoxides of the feedstock, feeding the oxidizer product to a rearrangement-esterification zone containing acetic anhydride at from about 0.degree. C. to 150.degree. C. to form an ester product comprising the diacetate and monoisopropyl-monoacetate derivatives of the feedstock, distilling the ester product to separate the diacetate and monoisopropyl-monoacetate derivatives, and recycling the monoisopropyl-monoacetate derivative back to the oxidizer.

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.

Abstract: A device for applying torque to a rotatable workpiece. The device is particularly constructed to loosen or tighten nuts or bolts which are difficult to turn due to rust, corrosion or the like. The device multiplies force (torque) that is applied to the handle of the device to a workpiece to be rotated thereby enabling a person to apply a relatively light force to the device and deliver a multiple of the force applied to the rotatable workpiece. The device of the invention is constructed so that it may be partially disassembled and folded to be conveniently stored until needed.
