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.

Abstract: Provided is a method of producing activated carbon from a resin composite made up of furanic polymer. The method includes producing a resin composite from feedstock (e.g., in the presence of an acid and a salt), combining the resin composite with a base to form an impregnated material, and carbonizing the impregnated material to produce the and salt activated carbon. Provided herein are also resin composites and activated carbon materials.

Abstract: Provided herein are methods of producing dialkylfurans, such as 2,5-dimethylfuran, and other alkyl furans, such as 2-methylfuran. For example, 2,5-dimethylfuran may be produced by reducing (5-methylfuran-2-yl)methanol or 2-(chloromethyl)-5-methylfuran.

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.

Abstract: The present disclosure provides methods to produce substituted furans (e.g., halomethylfurfural, hydroxymethylfurfural, and furfural), by acid-catalyzed conversion of biomass using a gaseous acid in a multiphase reactor, such as a fluidized bed reactor.

Abstract: Provided herein are methods of producing halomethylfuroic and acyloxymethylfuroic acid and ester compounds from furfural starting compounds. For example, 5-chloromethyl-2-furoic acid may be produced from 5-chloromethylfurfural, in the presence of various oxidants. Salts of the furoic acids may also be produced.

Abstract: Provided herein are (phenylene)dialkanamines, and methods of producing such (phenylene)dialkanamines from various furanyl and benzyl compounds. Such furanyl compounds may include, for example, bis(nitroalkyl)furans, bis(aminoalkyl)furans, and nitroalkyl(furan)acetonitriles. Such compounds may include, for example, bis(nitroalkyl)benzenes. Provided herein are also alkyldiamines, and methods for producing such alkyldiamines from furanyl compounds.
