    Abstract: An improved method for the manufacture of MIBK and DIBK from DMK and/or IPA, by reacting, in the presence of an aldol condensation catalyst, a gaseous mixture comprising hydrogen and DMK and/or IPA. The improvement is the use of a reaction pressure greater than 207 kPa (30 psig) to increase the ratio of MIBK to DIBK. In addition a method for the manufacture of MIBK and DIBK by reacting, in the presence of an aldol condensation catalyst, a gaseous mixture consisting essentially of DMK and/or IPA and optionally water.
