1. A REDUCTIVE CONDENSATION PROCESS FOR THE DIRECT PRODUCTION OF HIGHER MOLECULAR WEIGHT SATURATED ALDEHYDES FROM LOWER MOLECULAR WEIGHT SATURATED ALIPHATIC ALDEHYDES CONTAINING AN ALPHA HYDROGEN ATOM AND HAVING UP TO 10 CARBON ATOMS WHICH CONSISTINS OF REACTING SAID LOWER MOLECULAR WEIGHT SATURATED ALIPHATIC ALDEHYDE CONTAINING AN ALPHA HYDROGEN ATOM AT A TEMPERATURE OF ABOUT 0* TO 180* C. WITH AN AQEUOUS SOLUTION HAVING A PH OF FROM ABOUT 7 TO 13 CONTAINING COBALT IONS AND CYANIDE FROM ABOUT 7 TO 1O CONTAINING COBALT IONS AND CYANIDE ANIONS IN THE PRESENCE OF A HYDROGEN PRESSURE OF FROM ABOUT 1 TO 1,000 P.S.I., SAID AQUEOUS SOLUTION CONTAINING FROM ABOUT 2 TO ABOUT 10 CYANIDE ANIONS PER COBALT ION AND FROM ABOUT 0.001 TO ABOUT 1 MOLE OF COBALT ION PERMOLE OF THE SATURATED ALPHATIC ALDEHYDE CONTAINING AN ALPHA HYDORGEN ATOM.
