  • Publication number: 20140107380
    Abstract: A method is provided for producing bioderived dipropylene and tripropylene glycols without using propylene oxide. The method utilizes a bioderived (mono)propylene glycol as a feed, and in one embodiment performs an acid-catalyzed condensation process to convert the bioderived propylene glycol to products including at least dipropylene glycol and preferably including tripropylene glycol as well. Wholly biobased dipropylene glycol and tripropylene glycol products and derivative products made therefrom are described, with compositions of matter including the wholly biobased dipropylene glycol and tripropylene glycol or a derivative thereof and describing uses of the various wholly biobased products or of the compositions including the wholly biobased products. Biobased polypropylene glycols may be made in the same manner.

  • Publication number: 20140101988
    Abstract: The present disclosure relates to a method of converting glycerol into organic reaction products. The method may include mixing glycerol with a monohydric alcohol. The mixture of glycerol and monohydric alcohol is then reacted in the presence of a heterogeneous nano-structured catalyst, wherein the monohydric alcohol is present at subcritical/supercritical temperatures and pressures. This converts the glycerol into one or more reaction products, wherein the reaction products include an oxygenated organic reaction product. Ninety percent or greater of the glycerol is converted.

  • Patent number: 8637711
    Abstract: Aspects of the present invention are directed to novel methods for making discrete polyethylene compounds selectively and specifically to a predetermined number of ethylene oxide units. Methods which can be used to build up larger dPEG compounds (a) containing a wider range of utility to make useful homo- and heterofunctional and branched species, and (b) under reaction configurations and conditions that are milder, more efficient, more diverse in terms of incorporating useful functionality, more controllable, and more versatile then any conventional method reported in the art to date. In addition, the embodiments of the invention allow for processes that allow for significantly improving the ability to purify the intermediates or final product mixtures, making these methods useful for commercial manufacturing dPEGs. Protecting groups and functional groups can be designed to make purification at large scale a practical reality.
