Abstract
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.
Claims10
A method, comprising:
- converting a feedstock into 5-(halomethyl)furfural in the presence of (i) H+, (ii) X−, and (iii) a Group I or Group II cation, wherein [H+] is greater than 0 M and less than or equal to 8 M, and wherein X− is a halo anion.
Dependencies are inferred from the claim text.
