Catalyse Des Oxydations A Chaînes Ramifiées

Abstract

CATALYSE DES OXYDATIONS A CHAfNES RAMIFIEES J. ROUCHAUD et C. MPIANA (Kins/fasa) lsobutane (RH) dissolved in acetic acid (RH/AcOH = 0.3 g/g) has been oxidized by molecular oxygen (Po2-20 atm; Ptotal -45-55 atm) at 135 and 155°C.Acetone, t-butylalcoho! (t-BuOH) and methylacetate are the main products. Their distribution does not vary strongly(1ess than 10%) when the percentageof R H oxidized is between 8 and 25%. In the oxidation initiated by the r-butyl-hydro-
