  • Solid forms of 5-(halomethyl)furfural and methods for preparing thereof
    Patent number: 9718798
    Abstract: Provided are solid forms of 5-(halomethyl)furfural, including a crystalline form of 5-(chloromethyl)furfural. Provided are also methods for preparing solid forms of 5-(halomethyl)furfural by crystallization using certain solvents.
    Type: Grant
    Filed: September 11, 2015
    Date of Patent: August 1, 2017
    Assignee: MICROMIDAS, INC.

  • Methods for producing 5-(halomethyl) furfural
    Patent number: 9388151
    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.
