Abstract A process for preparing 2,2,4-trimethyl-1,3-pentadiol monoisobutyrate features that in the procedure of ester synthesis, the Ba(OH)2.8H2O is directly used in reaction to increase the product selectivity from 89% to more than 96% and decrease the product chromaticity from No.50 to NO.20; and in the aldol condensation procedure, the water and the NaOH aqueous solution are first loaded in reactor and the isobutylaldehyde is then slowly added while stirred to prevent over-heat which can result in not controlling the reaction easily.
