Low pressure one-step gas-phase process for production of methyl isobutyl ketone
TLDR
In this paper, a low-pressure one-step gas-phase process for the production and recovery of methyl isobutyl ketone (MIBK) is disclosed, which is designed to recover the additional heat associated with the reactor effluent via heating acetone feed and recycle (mixed acetone) before entering the reactor.Abstract:
A low-pressure one-step gas-phase process for the production and recovery of methyl isobutyl ketone (MIBK) is disclosed. One-step gas-phase synthesis of MIBK from acetone and hydrogen over nano-Pd/nano-ZnCr 2 O 4 catalyst at atmospheric pressure is used as an example. The said process is designed to recover the additional heat associated with the reactor effluent via heating acetone feed and recycle (mixed acetone) before entering the reactor. A compressor is introduced to the gas-phase process to increase slightly the reactor effluent pressure before this effluent is cooled and fed to a flash drum. The compressed reactor effluent is used to preheat hydrogen feed and recycle (mixed hydrogen) before entering the reactor. The separation scheme of low-pressure one-step gas-phase process comprises of several distillation columns used for MIBK separation and purification.read more

Production of alcohols
TL;DR: In this paper, a process for producing an alcohol product is described, in which a first feed composition comprising acetic acid is converted to a product comprising acetone; and a second feed composition, comprising at least part of the acetone produced in the first feed, is hydrogenated in the presence of a catalyst to produce a hydrogenation effluent comprising isopropanol.

Separation and Purification of Methyl Isobutyl Ketone from Acetone + Isopropanol + Water + Methyl Isobutyl Ketone + Methyl Isobutyl Carbinol + Diisobutyl Ketone Mixture.
TL;DR: It is shown that, in some cases, it is sufficient to study the two-dimensional scan of the phase diagram to predict its internal structure, and the sharp distillation was proved to be less energy-intensive.

Process for the production of methyl isobutyl ketone from acetone
TL;DR: In this article, a process for producing methyl isobutyl ketone from acetone is described, which is based on a two-stage process, with the first stage consisting of feeding a stream of hydrogen and a stream consisting of fresh dimethyl ketone and a fraction of the unconverted dissimilarity from the recovery section to the second stage.
