Descripción

General description

2,6-Dimethyl-4-heptanone (di-i-butyl ketone) is widely employed as an industrial solvent. It undergoes gas-phase reaction with the OH radical in the presence of NO_x to afford acetone and 2-methylpropanal. 2,6-Dimethyl-4-heptanone is formed as a product during the thermal degradation of Yttrium(III) isovalerate Y.

Application

2,6-Dimethyl-4-heptanone may be employed as a diluent for the isolation of pentanedioic acid by using Amberlite LA-2.
