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 translation: 本公开提供在操作条件下纯化5-（卤代甲基）糠醛组合物的方法，其包括5-（氯甲基）糠醛，其在该过程中减少或最小化5-（氯甲基）糠醛的分解或降解。 这些方法可以使用某些溶剂，操作条件和/或技术（例如，汽提）。 从该方法产生的气态5-（卤代甲基）糠醛可以冷凝或沉积以产生液体或固体形式的5-（卤甲基）糠醛。 固体5-（卤甲基）糠醛可以是无定形或结晶的。

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: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose, starch, sugar) and ethylene in the presence of a catalyst. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF), which may be converted into para-xylene by cycloaddition of ethylene to DMF. Para-xylene can then be oxidized to form terephthalic acid.

Abstract: Provided herein are methods that utilize polyhydroxyalkanoates (PHAs) as a substrate for further conversion to C4 and C5 compounds. Polyhydroxyalkanoates can undergo esterification to yield alkyl hydroxyalkanoates and alkyl alkenoates, which may serve as useful precursors in the production of alkadienes and alkenedioic acids, including for example butadiene and butenedioic acid.

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.
