  • Method for extracting organic compounds from aqueous mixtures
    Patent number: 8835660
    Abstract: The invention provides a method to extract organic compounds from aqueous mixtures, using a specially selected organic compound as an extraction liquid. The method can be applied to remove compounds such as acetic acid or ethanol from complex aqueous mixtures, including fermentation reactions or broths, and can be used for in situ extraction of products or by-products from a fermentation reaction. Some suitable extraction liquids for use in these methods include diethylene glycol dibutyl ether, tripropionin, and di(ethylene glycol) diisobutyl ether.
    Type: Grant
    Filed: August 22, 2011
    Date of Patent: September 16, 2014
    Assignees: The Regents of the University of California, BP Corporation North America Inc.
    Inventors: Amit A. Gokhale, Sasisanker Padmanabhan, Christopher Roberge

  • IONIC LIQUID PRETREATMENT OF CELLULOSIC BIOMASS: ENZYMATIC HYDROLYSIS AND IONIC LIQUID RECYCLE
    Publication number: 20130252285
    Abstract: The present invention relates to compositions and methods of pretreating cellulosic biomass with an ionic liquid. More specifically it relates to pretreating cellulosic biomass in an ionic liquid and adding a salt containing a kosmotropic anion to facilitate separation of precipitated solids, the aqueous phase, and the ionic liquid phase. The ionic liquid phase may be recycled in a subsequent pretreatment step, and the precipitated solids are enzymatically hydrolyzed to produce smaller oligomers of cellulose, cellbiose, and/or glucose. The kosmotropic anion facilitates phase separation where the aqueous phase contains very low concentrations of the ionic liquid.
