  • Patent number: 9868712
    Abstract: The invention provides a method for preparing a 2,5-dialkyl furan. The method includes forming a reaction mixture containing a catalyst, a hydrogen source, and 2-haloalkylfuran starting material under conditions sufficient to form the 2,5-dialkyl furan. The 2-haloalkylfuran starting material can be derived from biomass, and the 2,5-dialkyl furan product can be used as a biofuel or as a chemical feedstock.

  • Patent number: 9556137
    Abstract: Provided herein are methods for preparing alkylfurans, such as 2,5-dialkylfurans and 2-alkylfurans. Furfural or 5-alkylfurfural can be reacted with aniline or diaminobenzene, or derivatives thereof, to form the corresponding imine, which can be reduced to form alkylfurans and to regenerate the aniline or diaminobenzene, or derivatives thereof. The alkylfuran may be, for example, 2,5-dimethylfuran or 2-methylfuran.

  • Publication number: 20160264876
    Abstract: The present invention provides methods for preparing a C6-C10 alkane, and mixture thereof. The methods include forming a reaction mixture containing an angelica lactone dimer, a catalyst, and a hydrogen source under conditions sufficient to reduce the angelica lactone dimer, thereby preparing the alkane. The methods can be used to prepare branched alkanes useful for fuels. Methods for preparing an angelica lactone, methods for preparing an angelica lactone dimer, and methods for reducing a lactone to an alkane are also described.

  • Patent number: 7829732
    Abstract: Paper, cotton, corn stover, straw, and wood are converted into furanic products in high yields (based on their cellulose content) using a simple, inexpensive process involving concurrent hydrolysis, dehydration, and substitution reactions coupled with continuous extraction into an organic phase. In a simultaneous process, the hemicellulose fraction of these substrates is converted into furfural, and together these constitute an efficient means for the total exploitation of the carbohydrate content of biomass.

  • Patent number: 7723322
    Abstract: The present invention provides a compound of the formula wherein R1 is an ammonium bridge. The compounds of the present invention can be linked to a biological molecule that targets a specific type of cell. The compounds of the present invention can trap isotopic fluorine so that when the biological molecule accumulates in the desired type of cell, the isotopic fluorine is imaged by positron emission tomography (PET).
