Abstract: Disclosed are novel catalyst systems comprising (1) a diorgano fluorophosphite ligand; (2) rhodium, wherein the ratio of gram moles fluorophosphite ligand (1) to gram atoms of rhodium is at least 1:1; and (3) a Group VIII metal, other than rhodium, or Group VIII metal-containing compound, in an amount effective to reduce the formation of HF during the use of the catalyst system. The presence of the other Group VIII metal decreases the amount of hydrogen fluoride produced during the use of the catalyst system. The hydrogen fluoride originates from very low level degradation of the ligand. Also disclosed are novel catalyst solutions of the aforesaid catalyst system and the use of the catalyst system in the hydroformylation of olefins to produce aldehydes.

Abstract: The invention involves a means of increasing the scorch delay period (scorch time) for standard bisphnol-cured fluoroelastomers (abbreviated as “FKM;” these are copolymers of vinylidene fluoride and hexafluoropropene, optionally also containing additional monomers such as tetrafluoroethylene). The invention entails particular subtituted monophenols (butylparaben or propylparaben) and/or mixtures of these with methylparaben and/or inorganic solids, and the inclusion of these particular substituted monophenols and/or blends in an FKM compound. These particular substituted monophenols are effective as scorch inhibitors of bisphenol-cured FKM, and are also effective as processing aid.
