摘要:
A method of oxidizing olefins or alkanes by contacting with oxygen and a catalyst composition of the formula:Ru.sub.3 O[OCO(CF.sub.2).sub.y CF.sub.3 ].sub.6 LWherein: Ru are reuthenium atoms having a formal oxidation state of +2 or +3,L is a neutral or anionic ligand,Y is an integer from 0 to 6, andx is an integer from 1 to 3; and an anion.
摘要:
A nitrile-containing mixture, which includes a nitrile dissolved in a higher alcohol solvent, and hydrogen are fed to a reactor containing a catalyst. An amine is produced by hydrogenating the nitrile that is dissolved in the higher alcohol solvent. In a preferred embodiment, the reactor also contains a caustic solution. The preferred nitrile-containing mixture includes octadecaneditrile (ODDN) and hexanol to produce a preferred octadecanediamine (ODDA) through hydrogenation.

Apparatuses for safely warming food and methods of manufacturing such an apparatus are provided. A heating element may be connected to a base such that there is air between the heating element and the removable top plate, the heating element cannot directly heat a removable top plate of the apparatus, and the heating element must heat the air between the heating element and the removable top plate before heating the removable hot plate. A resetting thermal fuse may be connected to a fuse holder connected to a wall of the base of the apparatus such that the thermal fuse is not directly affected by changes in temperature in the housing of the apparatus, and is affected by changes in temperature of the air between the heating element and the removable top plate.
