  • Publication number: 20230032460
    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.

  • Publication number: 20200146284
    Abstract: The disclosure relates to a method for treating an active beehive infested with pests. The method includes delivery of an oligomeric polyester including polyol backbone units, diacid backbone units, and formic acid capping units. Hydrolysis of the oligomeric polyester in the beehive upon exposure to environmental water to release formic acid and diacid over time, which kill the pests. The released formic acid is a relatively volatile liquid, allowing it to reach pests essentially anywhere in the hive. The diacid (such as oxalic acid) is generally a non-volatile solid, but it can be transported throughout the hive via normal bee movement within the hive, thus reaching pests beyond the initial point of application.

  • Patent number: 10392317
    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.
