Abstract A reaction process for linked preparation of methylisobutyl ketone (MIBK) and diisobutyl ketone (DIBK) features use of ordinary-pressure one-step gas-phase synthesis, including adding composite catalyst to isopropanol or the mixture of isopropanol and acetone. Said composite catalyst contains ZnO as main component (20-80%), CuO (20-60%) and macroreticular Al2O3 (10-50%). Its advantages include linked output of MIBK and DIBK, high activity, high selectivity (up to 30% separately) and high transfer rate of isopropanol (up to 90% or more).
