Abstract (en)

[origin: WO0144156A1] Neo-acid compounds can be used as non-reactive catalysts in carrying out esterification reactions. The neo-acids can be isolated by subjecting a neo-acid composition to esterification with an excess of alcohol and recovering the non-reactive neo-acid fraction therefrom. The non-reactive fraction can be used as a non-reactive catalyst in a subsequent esterification.
