Methyl isobutyl ketone (MIBK) is a chemical intermediate and important solvent. MIBK is produced from acetone and hydrogen in three-step process through diacetone alcohol and mesityl oxide intermediates. MIBK is also manufactured from acetone and hydrogen in one-step liquid phase process. The one-step synthesis of MIBK from acetone and hydrogen over nano-Pd/nano-ZnCr2O4 catalyst at 1 atm is put forward. The process is designed to recover the additional heat associated with the reactor effluent through heating acetone feed. A compressor is introduced to the process to increase the pressure of reactor effluent before it is cooled down and fed to a flash drum. The compressor outlet stream is used for preheating hydrogen feed. The separation scheme of the process consists of several distillation columns where MIBK is separated and purified. The process reduces both capital and operating costs of MIBK synthesis.
