2653. ------. [PIER, M., AND CHRISTMANN, F.] (Alien Property Custodian). Liquid Lubricating Oils from Paraffin Wax. United States Patent 2,318,625, May 11, 1943. Chem. Abs., vol. 37, 1943, p. 6449.

Oils are produced by subjecting a straight-chain paraffin wax to the action of a halogenating agent such as Cl, under conditions adapted to convert it into halogen derivatives of substantially the same number of C atoms, and subjecting the resulting product to the action of a chemical condensing agent, such as AlCl3, in the presence of a bleaching earth to make oils of high viscosity index.
