Abstract: A process for preparing a catalyst, and catalysts prepared thereby. The process includes selecting a catalyst support and mixing it with one or more chromium containing compounds oxidizable to a Cr+6 state or already in a Cr+6 state, and with one or more transition metal catalyst component, and calcining the catalyst support while oxidizing any chromium containing compound to a Cr+6 state, and spray drying the catalyst support to form catalyst particles. The catalyst supports are characterized by a surface area greater than 50 m2/gram and a pore volume greater than 0.5 cc/gram at the time of mixing the catalyst support with the chromium containing compound.

Abstract: The present invention provides strategies for making cyclic triamines. Reactant media including certain precursors and/or certain types of catalysts can be converted into cyclic triamines with improved conversion and selectivity. The strategies can be incorporated into reactions that involve transamination schemes and/or reductive amination schemes. In the case of transamination, for instance, using transamination to cause ring closure of higher amines in the presence of a suitable catalyst leads to desired cyclic triamines with notable conversion and yield. In the case of reductive amination, reacting suitable polyfunctional precursors in the presence of a suitable catalyst also yields cyclic triamines via ring closure with notable selectivity and conversion. Both transamination and reductive amination methodologies can be practiced under much milder temperatures than are used when solely acid catalysts are used. Preferred embodiments can produce reaction mixtures that are generally free of salt by-products.

Abstract: A method for testing a mechanical integrity of an insulating layer covering a conductor in a cable, a longitudinal void being defined inside the insulating layer in a region of the conductor. A first end of the insulating layer is blocked. A compressed gas is injected at a second end of the insulating layer so that the gas enters and travels the longitudinal void inside the insulating layer towards the first end. A gas pressure inside the insulating layer is measured at least near the second end. Injection of the compressed gas is stropped after a predetermined injection time period. A variation of the gas pressure inside the insulating layer is monitored during a diagnostic time window succeeding to a transitional time period following the stopping of the injection. Integrity of the insulating layer is determined based on the variation of the gas pressure during the diagnostic time window.
