A method for maximizing the yield of 2,2,4-trimethyl-1,3-pentanediol di-2-ethylhexanoate (TMPD di-2-ethylhexanoate) from the reaction of 2,2,4- trimethyl-1,3-pentanediol (TMPD Glycol) and 2-ethylhexanoic acid through the intermediate compound 2,2,4-Trimethyl-1,3-pentanediol-2-ethylhexanoate (TMPD mono-2-ethylhexanoate) is disclosed. The method involves maintaining a water level in the reactor of at least 0.10 weight%, and preferable above 0.20 weight%, thereby reducing formation of 2,2,4- trimethylpent-3-enyl-2-ethylhexanoate, an undesirable by-product.
