METHODS FOR PRODUCING 5-(HALOMETHYL)FURFURAL

摘要

The present disclosure provides methods to produce 5-(halomethyl)furfural, including 5-(chloromethyl)furfural, by acid-catalyzed conversion of C6 saccharides, including isomers thereof, polymers thereof, and certain derivatives thereof. The methods make use of acids with lower concentrations, and allows for conversion of sugars into 5-(halomethyl)furfural at higher temperatures and faster reaction or residence times.

主权项

1. A method for producing 5-(halomethyl)furfural, comprising:
a) combining a feedstock, an acid, and a salt in a reaction vessel to form a reaction mixture, wherein: the acid is HX, wherein X is halo; the salt is Ar+(X−)r, wherein:
Ar+ is a Group I or Group II cation, andX− is an halo anion; and the reaction mixture has a [H+] less than 12 M; and b) producing 5-(halomethyl)furfural from at least a portion of the feedstock in the reaction mixture.
