Inventor: MILLER GLENN A
IPC: C07C45/50
Filed: 2008-03-12
Abstract: A continuous hydroformylation process for producing a mixture of aldehydes with improved flexibility and stability of a normal/branched (N/I) isomer ratio of the product aldehydes. The process involves reacting one or more olefinically-unsaturated compounds with carbon monoxide and hydrogen in the presence of an organopolyphosphite ligand and an organomonophosphite ligand, at least one of such ligands being bonded to a transition metal to form a transition metal-ligand complex hydroformylation catalyst; the process being conducted at a sub-stoichiometric molar ratio of organopolyphosphite ligand to transition metal, at a super-stoichiometric (>2/1) molar ratio of organomonophosphite ligand to transition metal, and at a carbon monoxide partial pressure in the inverse order region of the hydroformylation rate curve; and controlling and varying the N/I isomer ratio by varying the concentration of organopolyphosphite ligand relative to transition metal.

Abstract: A thermally activated electrical interrupt device incorporates a thermally activated portion engaging with an elec-trical interrupt portion. The thermally activated material expands when heated, causing an interrupt control rod to open an electri-cal contact. When the interrupt device is placed into an interrupt state, a reset mechanism maintains the interrupt control rod in the interrupt state until specifically reset. An actuating shaft is in operational communication with at least one electrical contact. The actuating shaft is maintained in a thermal monitoring position until an interrupt control rod is moved via a thermally expanding material and engages with the actuating shaft, releasing it from the thermal monitoring position. The actuating shaft is projected via a biasing member to cause a change in state of the electrical contact. The actuating shaft remains in the interrupt state until the user resets the switch.
