Abstract:
The incremental yield of hydrocarbons having five or more carbon atoms in a cracked product from a thermal cracking process is increased by contacting or treating the tubes of a thermal cracking furnace with a composition comprising tin and silicon.
Abstract:
For a given percentage decomposition, the decomposition temperature of an organosilicon compound is reduced by admixing with the organosilicon compound a decomposition promoting organotin compound. The amount of decomposition promoting organotin compound admixed with the organosilicon compound is sufficient to effectively lower the decomposition temperature of the organosilicon required for a given percentage decomposition.
Abstract:
A Pd/heteropolyacid/surfactant catalyst system, when used with proper diluents, improves the oxidation of olefins to ketones, while reducing corrosive effects.
Abstract:
A hydrocarbon feedstock containing at least one paraffin hydrocarbon and an odor-causing impurity is deodorized by contact with a deodorizing agent. The deodorizing agent is a mixture of nickel oxide and a rare earth metal oxide and the odor-causing impurity is from the group consisting of sulfides, mercaptans, olefins, and oxygenated olefins. The feedstock is contacted with the deodorizing agent at a temperature not exceeding 150.degree. C.
Abstract:
An aromatic hydrocarbon is contacted under suitable hydroalkylation conditions with a composition comprising a calcined, acidic, nickel and rare earth-treated crystalline zeolite.

A Pd/heteropolyacid/surfactant catalyst system, when used with proper diluents, improves the oxidation of olefins to ketones, while reducing corrosive effects.
Abstract:
An aromatic hydrocarbon is contacted under hydroalkylation conditions and in the presence of hydrogen with a composition comprising at least one ruthenium compound impregnated on a calcined, acidic, nickel and rare earth-treated crystalline zeolite support.
Abstract:
Phenol-, cyclohexanone-, and cyclohexylbenzene-containing mixtures are extractively distilled employing an N-substituted lactam to provide overhead a high purity cyclohexanone and a kettle product containing phenol, cyclohexylbenzene when it is present in the mixture treated, and the N-substituted lactam.
Abstract:
Phenol-, cyclohexanone-, and cyclohexylbenzene-containing mixtures are extractively distilled to provide overhead of cyclohexanone and a kettle product substantially free of cyclohexanone by employing an N,N-disubstituted amide. When substantially no cyclohexylbenzene is present in the mixture to be extractively distilled, the kettle product will be essentially composed of the amide and phenol.
