Abstract: A preferred process for producing 3-hydroxy-2,2,4-trimethylpentyl isobutyrate is described. The spent aqueous phase from an alkali metal hydroxide-catalyzed isobutyraldehyde condensation is concentrated in alkali metal isobutyrate salt, and the concentrated medium is introduced into a subsequent condensation to advantageously modify the isobutyraldehyde reaction. Increased conversions and productivities can thus be achieved. Preferred continuous processes, as well as preferred processes of controlled reaction duration and reactant/catalyst/salt ratios are also described. Further described is a preferred process for producing the diisobutyrate ester of 2,2,4-trimethyl-1,3-pentanediol, which in a preferred mode also achieves a desirable coproduction of the diol and its monoisobutyrate ester.
