Abstract: Bicyclic and monocyclic terpenes are oligomerized by contact over a zeolite catalyst to produce high boiling lube oil traction fluid having a high traction coefficient. The traction fluid comprises dimers, trimers and tetramers of the bicyclic and monocyclic terpenes. The lube oil is catalytically hydrogenated to obtain a saturated cycloparaffin hydrocarbon oil traction fluid.

Abstract: Alkyl groups in trialkyl aluminum are displaced by .alpha.-olefins in the presence of a nickel catalyst. The displaced alkyl group evolve as .alpha.-olefins. The displacement is fast and the catalyst is then poisoned with a catalyst poison such as lead to prevent undesired side reactions such as isomerization of .alpha.-olefins to internal olefins or dimerization to vinylidene olefins.

Abstract: A method for the preparation of biaryl compounds is disclosed which comprises contacting an aromatic halide in the presence of a catalyst comprising zerovalent nickel, a bidentate phosphorus-containing coordinating ligand and a reducing metal in a polar, aprotic solvent system for a time and under conditions suitable for the formation of biaryl compound.

Abstract: The present invention concerns a catalyst for alkylation of alkyl aromatics with olefins, i.e. alkylating toluene, a procedure for the production of the catalyst, and a procedure for carrying out the alkylating of the toluene. The catalyst system contains sodium oxide (Na.sub.2 O) on a potassium carbonate (K.sub.2 CO.sub.3) carrier, preferably at about 10 to 70%.

Abstract: Alumina-composited zeolite catalysts are activated by contact with an aqueous ammonium solution under ammonia gas pressure such that a pH of at least about 8 is maintained in the solution. The treated zeolite may thereafter be calcined without prior ammonium-exhange to provide the zeolite in the hydrogen form. Catalysts which are activated in this manner are useful for converting alcohols and/or ethers to hydrocarbons including aromatics.

Abstract: Herein is described an ocular composition comprising an ocular decongestant such as phenylephrine and certain labdane derivatives which are intraocular pressure lowering agents. The composition not only markedly reduces the ocular reddening otherwise produced by such labdane compounds, but also unexpectedly prolongs and frequently potentiates their intraocular pressure lowering effect. Both of these effects are very beneficial to the use of such labdanes for the treatment of glaucoma.

Abstract: Diphenylamine which is unsubstituted or substituted by alkyl or alkoxy groups can be prepared by treating appropriately substituted dicyclohexylamine with 1-10 bar of H.sub.2 over catalysts containing 0.05-5% by weight of rhodium at 250.degree.-450.degree. C. In addition to rhodium, the catalysts contain at least one other platinum metal from the group consisting of palladium, platinum and iridium on a support containing the noble metals in a total amount of 0.05-5% by weight, the percentage by weight of rodium with respect to all noble metals being 10-90%, and furthermore containing additives of 1-6% by weight of an alkali metal hydroxide and 1-6% by weight of an alkali metal sulphate. All percentages are based on the total weight of the catalyst.
