Abstract
Official abstract text for this publication.
Disclosed are compositions and methods for the production of mono-esters and di-esters from the reaction of HMF and a reactant selected from a diacid or a diacid derivative; typical reactants are PAN, phthaloyl dichloride, dimethyl phthalate, maleic acid, and maleic anhydride or mono-esters that can be prepared from HMF and MAN.
First claim
Opening claim text (preview).
We claim: 1. A method for di-ester synthesis comprising: mixing 5-(hydroxymethyl)-2-furfuraldehyde and dimethyl phthalate with a suitable catalyst; and heating at about 80° C. to about 110° C. while stirring for about 2 to about 4 hours. 2. A method for di-ester synthesis comprising: melting 5-(hydroxymethyl)-2-furfuraldehyde: adding phthalic anhydride and an optional esterification catalyst to the molten 5-(hydroxymethyl)-2-furfuraldehyde while stirring…
