    摘要: Disclosed are processes to prepare monocarboxylic acid esters (mono- and/or diesters) of polytrimethylene ether glycol that are substantially free of residues from the catalyst used to produce the polytrimethylene ether glycol esters, as well as methods for their preparation and end uses thereof. The esters, such as the bis-2-ethylhexanoate esters, have uses as functional fluids.
