Abstract:
This present invention relates to a disproportionation catalyst and to a process for preparing a disproportionation catalyst comprising forming a calcined composite comprising at least one of molybdenum and rhenium supported on an inorganic oxide support and contacting the calcined composite with an organoborane compound. The invention further relates to a process for the disproportionation of olefinic hydrocarbons comprising contacting at least one olefinic hydrocarbon with a catalyst comprising at least one of molybdenum and rhenium supported on an inorganic oxide support promoted with an organoborane compound. More specifically, the invention relates to the uses of an organoborane compound promoted molybdenum and rhenium supported on an inorganic oxide support for the production of linear alpha olefins from a mixture of internal olefins and ethylene. The invention also relates to the application of the described promoted catalyst for the production of 1,6-heptadiene and 1,6-octadiene from the reaction of cyclopentene with ethylene and propylene, respectively, and the fact that the presence of organoborane in the catalyst allows the reaction to be carried out at very mild temperature while obtaining high product selectivity.

Abstract:
Disclosed are novel isocyanate prepolymers and novel secondary amines, both prepared from alkyl diisocyanates and secondary isopropyl derivatives of polyoxyalkylene diamines. The molar ratios, reaction procedures (i.e. inverse addition of reactants) and solvent determine the products. Most of the products are light colored and nongelled.The isocyanate prepolymers are useful in the field of polyurethanes and the novel secondary amines are useful in epoxy coatings applications.
Abstract:
A process in which a dialdehyde is reacted with a polyoxyalkylene glycol to form a dialdehyde glycol condensate which is alkoxylated with propylene oxide, butylene oxide or mixtures thereof and the resulting product is then catalytically aminated to provide, for example, a tetramine is disclosed. These compounds are useful as curing agents for epoxy resins and for reaction with isocyanates to prepare polyurea elastomers and to manufacture articles, such as automotive body panels by reaction injection molding.
