Abstract: Apparatus for making a transition from leads (12-26) of a temperature measuring thermocouple to extension wires (44-58) within a hermetically sealed cable sheath (60) of small diameter. The interior of the cable sheath (60) is shielded from electromagnetic radiation by an electrically conductive liner (62). A thermally conductive, electrically insulating material (66) surrounds the intermediate junctions (28-42). The temperature of the intermediate junctions (28-42) is measured (64) providing a signal to compensate the voltage generated by the temperature measuring thermocouples due to the thermoelectric effect of the intermediate junctions (28-42).

Abstract: A process for removing iron pentacarbonyl from carbon monoxide feed gas, comprising contacting the gas with a removal agent comprising alkali metal hydroxide in association with a high boiling hydroxylic solvent to form a nonvolatile iron carbonylate salt, and separating the gas from said agent and the salt. Preferably, the removal agent is adsorbed on a porous support such as diatomaceous earth at a concentration of from about 1% to about 40% by weight of the support, and the solvent is selected from one or mixtures of ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 2,2,4-trimethyl-1,3-pentanediol, glycerine, triethanolamine, 1,4-butanediol, 1,2-propanediol, 1,3-butanediol, 2,5-hexanediol, 1-hexanol and 2-hexanol.

Abstract: This invention concerns an oxo process, either batch or continuously operated, for the preparation of aldehydes, principally in relatively high proportions of branched isomer, from olefins and synthesis gas employing an unmodified rhodium catalyst feed or recycle such as the rhodium salts of organic carboxylic acids. More particularly the invention concerns such a process wherein at least a portion of the reaction medium, e.g., the oxo reactor effluent, is contacted with a ligandizing compound such as triphenylphosphine, prior to product recovery by distillation, such that the rhodium catalyst is converted to a stable form and not lost by plating out on the distillation column or base heater during the distillation. Thereafter, the catalyst is deligandized and regenerated by air treatment and reused in the process.

Abstract: The present invention provides a process for the preparation of ethylene glycol and glycerine by a selective electrolysis that cleaves the carbon-carbon bonds of carbohydrate-derived polyols into two- and three-carbon units. The intermediate products can then be reduced to the desired ethylene glycol and glycerine products using standard reduction technology. The electrolysis is conducted in the presence of an electrolysis medium which contains manganese.

Abstract: Disclosed is an improved process for the homologation of alkanols to obtain the next higher alkanol homolog by the cobalt-catalyzed reaction of an alkanol reactant with carbon monoxide and hydrogen under homologation conditions. The improvement comprises carrying out the homologation process in the presence of a perfluorocarboxylate anion.

Abstract: Rhodium hydroformylation catalysts are regenerated by a novel process which includes the steps of removing the catalyst to be regenerated from the hydroformylation reaction, adjusting the aldehyde contents of the catalyst containing stream so as to have at least one mole of aldehyde present per mole of rhodium and ligand present in the catalyst, treating the aldehyde containing catalyst stream with oxygen or oxygen containing gas at a temperature less than the boiling point of the aldehyde, removing any solid material formed during the oxidation and adjusting the ligand to rhodium ratio as required for use in the hydroformylation reaction.
