Abstract
The present disclosure provides methods to produce 5-(halomethyl)furfural, including 5-(chloromethyl)furfural, by acid-catalyzed conversion of biomass. The methods make use of certain organic solvents with temperature-dependent solubility for 5-(halomethyl)furfural. This allows for temperature-dependent phase separation of the 5-(halomethyl)furfural from the reaction mixture. In certain embodiments, solid 5-(halomethyl)furfural may be obtained. The solid 5-(halomethyl)furfural obtained may be amorphous or crystalline.
