Abstract

The present disclosure provides methods for purifying a 5-(halomethyl)furfural composition, including 5-(chloromethyl)furfural, at operating conditions that decrease or minimize the decomposition or degradation of 5-(chloromethyl)furfural during the process. The methods may employ certain solvents, operating conditions, and/or techniques (e.g., gas stripping). The gaseous 5-(halomethyl)furfural produced from the process can be condensed or deposited to yield 5-(halomethyl)furfural in liquid or solid form. The solid 5-(halomethyl)furfural may be amorphous or crystalline.
