Abstract: A PROCESS FOR PRODUCING NORMAL PARAFFIN OXIMES AND, IN PARTICULAR, NORMAL PARAFFIN OXIMES HAVING FROM 10 TO 13 CARBON ATOMS WHEREIN A C10 TO C13 NORMAL PARAFFIN IS PHOTOCHEMICALLY REACTED WITH A GASEOUS NITROSATING AGENT, THE NITROSATING AGENT PARTIAL PRESSURE BEING AT LEAST 125 MM. HG AND THE PHOTOLYTIC REACTION CONDUCTED UNDER THE INFLUENCE OF LIGHT EXCLUDING WAVE-LENGTHS BELOW 200 MILLIMICRONS. THE PROCESS IS ADMIRABLY SUITED FOR THE PRODUCTION OF NORMAL PARAFFIN OXIMES FROM MIXTURES OF C10 TO C13 NORMAL PARAFFINS.

Abstract: A PROCESS FOR PREPARATION OF ZINC DIALKYL DITHIOPHOSPHATES WHICH COMPRISES REACTING, IN A CLOSED SYSTEM, DIALKYLDITHIOPHOSPHORIC ACIDS WITH A BASIC ZINC SALT IN A HEPTANE SLURRY AT TEMPERATURES RANGING FROM ABOUT 180*300*F. AND UNDER AUTOGENOUS PRESSURE CONDITIONS, THE RESULTING ZINC DIALKYLDITHIOPHOSPHATES SERVING AS ANTIOXIDANTS AND AS ANTICORROSION AND ANTIWEAR AGENTS IN A VARIETY OF LUBRICATING OIL COMPOSITIONS.

Abstract: It has been discovered that heating C4-C17 internal olefins to 300* to 500*F under pressures of 1000 to 3500 psig for 1 to 20 hours with an oxo catalyst prior to contacting with hydrogen results in a higher selectivity to primary alcohols than does the conventional hydroformylation procedure of heating all the reactants together.
