20140121430 | RENEWABLE PARA-XYLENE FROM ACETIC ACID - A process is described for making renewable para-xylene, comprising converting acetic acid to isobutene in the presence of a catalyst then converting the acetic acid-derived isobutene to a product composition including para-xylene. The catalyst can be a Zn | 05-01-2014 |
20140128650 | RENEWABLE OLEFINS FROM A MIXTURE OF ACETIC ACID AND PROPIONIC ACID - A process is described for making a product mixture including isobutene, propylene, 1-butene, 2-butene 2-methyl-1-butene and 2-methyl-2-butene from a mixture of acetic acid and propionic and through reaction in the presence of a source of hydrogen and of a mixed oxide catalyst, for example, a Zn | 05-08-2014 |
20140371472 | METHOD OF MAKING ISOIDIDE - Disclosed is a process for the preparation of isoidide from isosorbide. An aqueous solution of isosorbide is subjected to epimerization in the presence of hydrogen under the influence of a catalyst comprising ruthenium on a support, preferably a carbon support. The process of the invention can be conducted using a relatively low hydrogen pressure, and leads to a desired distribution of epimers, favoring isoidide over isomannide and isosorbide. | 12-18-2014 |
20150210607 | USE OF BYPRODUCT ACETIC ACID FROM OXIDATIVE METHODS OF MAKING ACRYLIC ACID AND/OR METHACRYLIC ACID - Processes are described for improved utilization of the byproduct acetic acid universally produced in various oxidative processes for making acrylic acid and methacrylic acid, wherein at least a portion of the byproduct acetic acid is converted to isobutene and optionally to one or more further value-added products which may be prepared from isobutene. | 07-30-2015 |
20150210608 | RENEWABLE ISOBUTENE AND ISOPRENE FROM A MIXTURE OF ACETIC ACID AND PROPIONIC ACID - A process is described for making renewable isobutene and renewable isoprene, comprising converting a mixed acid feed including acetic acid and propionic acid to a product mixture including isobutene and at least one or both of 2-methyl-1-butene and 2-methyl-2-butene in the presence of a catalyst, separating isobutene from the product mixture and dehydrogenating either or both of the 2-methyl-1-butene and 2-methyl-2-butene in the remainder to provide isoprene. | 07-30-2015 |
20150217273 | STABLE MIXED OXIDE CATALYSTS FOR DIRECT CONVERSION OF ETHANOL TO ISOBUTENE AND PROCESS FOR MAKING | 08-06-2015 |
20150218077 | PROCESSES FOR MAKING METHACRYLIC ACID - Processes are described for making methacrylic acid via methacrolein from a biobased isobutene, wherein the biobased isobutene is prepared from ethanol or from acetic acid in the presence of a Zn | 08-06-2015 |
20150239799 | PROCESS AND CATALYST FOR CONVERSION OF ACETIC ACID TO ISOBUTENE - A process is disclosed for converting acetic acid to isobutene in the presence of a catalyst. In certain embodiments, a Zn | 08-27-2015 |
20150239800 | PROCESS AND CATALYST FOR CONVERSION OF ACETIC ACID TO ISOBUTENE AND PROPYLENE - A process is disclosed for converting acetic acid to propylene and isobutene as the principal hydrocarbon products made, in the presence of a catalyst and in the further presence of hydrogen. In certain embodiments, a Zn | 08-27-2015 |
20150239803 | PROCESS FOR MAKING BIOBASED ISOPRENE - Processes are described for making biobased isoprene, wherein a biobased isobutene prepared from acetic acid in the presence of a catalyst is combined with a formaldehyde source to form a reaction mixture, and the reaction mixture is reacted to yield biobased isoprene. In certain embodiments, methyl-tert-butyl ether prepared by reacting the same biobased isobutene with methanol serves as a formaldehyde source, being oxidatively cracked to produce formaldehyde as well as isobutene for being converted to the biobased isoprene. | 08-27-2015 |
20150239812 | PROCESS FOR MAKING BIOBASED FUEL ADDITIVES - Wholly biobased MTBE and ETBE fuel additive materials are described, together with fuel compositions including such additives and processes for making the wholly biobased MTBE and ETBE using isobutene prepared from acetic acid in the presence of a Zn | 08-27-2015 |
