Publication number: 20210340088Abstract: The disclosure relates to methods for separating mixtures of polyols, in particular mixtures of two of more different vicinal diols having close boiling points, thus making them difficult or impossible to separate using conventional distillation techniques. The polyol mixture is reacted with an aldehyde or ketone acetalization agent to form one or more acetals as corresponding acetalization reaction products. The acetalization reaction products are more easily separable either from each other (such as via distillation) or from an unreacted vicinal diol (such as via extraction, settling, or other phase separation). After separation, hydrolysis is performed on the acetalization reaction products to recover the vicinal diols as separate, purified components. The methods provide cost-effective processes for separating different polyols originally formed in admixture.Type: ApplicationFiled: October 7, 2019Publication date: November 4, 2021Inventors: Dennis J. Miller, Carl T. Lira, Lars Peereboom, Scott F. Parker, Thomas D. Dionise, William G. Killian

Patent number: 9994539Abstract: The disclosure relates to a method for forming 2,5-furan dicarboxylic acid (FDCA) from aldaric acids. The aldaric acids are dehydrating and cyclizing via acid catalysis to form the FDCA product. Aldaric acids such as galactaric acid, gularic acid, mannaric acid, and glucaric acid can be used in the disclosed method, and the aldaric acids can be obtained from form renewable biomass sources which contain pectin, alginate, and/or other biomass carbohydrates. The FDCA can be used as a renewable feedstock for consumer product polymeric materials such as polyalkylene furoate polymers.Type: GrantFiled: July 11, 2017Date of Patent: June 12, 2018Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: Dennis J. Miller, Lars Peereboom, Evan Wegener, Matthew Gattinger

Patent number: 9260403Abstract: Provided are methods of producing 2,5-furandicarboxylic acid (FDCA) from renewable sources such as seaweed, alginate, oligoalginate, pectin, oligopectin, polygalacturonate, galacturonate, and/or oligogalacturonate. The sugars in the renewable sources can be converted into one or more intermediates such as 4-deoxy-L-erythro-5-hexoseulose uronate (DEHU), 4-deoxy-L-threo-5-hexosulose uronate (DTHU), 5-hydroxymethyl furfural (HMF), 2,5-dihydroxymethyl furan (DHMF), and 5-formyl-2-furancarboxylic acid (FFA), which can be converted into FDCA by dehydration and cyclization to produce 5-formyl-2-furancarboxylic acid (FFA), followed by oxidation to produce FDCA. DEHU or DTHU may also be converted into FDCA by oxidation to produce 2,3-dihydroxy-5-oxohexanedioic acid (DOHA), which then undergoes dehydration and cyclization to produce FDCA.Type: GrantFiled: March 28, 2014Date of Patent: February 16, 2016Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: Yasuo Yoshikuni, Susan R. Cooper, Adam J. Wargacki, Leo E. Manzer, James F. White, Lou Kapicak, Dennis J. Miller, Lars Peereboom

Patent number: 9090556Abstract: The disclosure relates to a process for forming an acyloxy carboxylic acid or a derivative of the acid. A hydroxy acid compound is reacted with a carboxylic acid in a reaction vessel and in the presence of a catalyst, such as in a reactive distillation column containing the catalyst. The reaction product formed in the reaction vessel includes an acyloxy carboxylic acid compound, which can be removed continuously from the vessel in a product stream. Another product stream containing unreacted (excess) carboxylic acid and/or reaction byproducts such as water can be separately removed continuously from the reaction vessel.Type: GrantFiled: December 7, 2012Date of Patent: July 28, 2015Assignee: BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: Dennis Miller, Carl T. Lira, Lars Peereboom, Aspi K. Kolah
