The esterification reaction can also proceed via conversion of the crotonic acid to crotonyl chloride and then reacted with an alcohol. No. As renewable sources of energy and raw materials, agricultural feedstocks based on crops are the ultimate replacement of declining oil reserves. Kim, K.J., et al., “Thermal Degradation Behavior of Poly(4-hydroxybutyric acid)”, Polymer Degradation and Stability, 91:2333-2341 (2006). The company has inked a number of PHA licenses already. The MOU regards a strategic commercial manufacturing arrangement for specialty PHAs, including the Company's newly launched amorphous PHA ("a-PHA")Under the non-binding MOU, the companies have agreed to work together toward the successful conclusion of definitive agreements under which CJ will fund, construct and operate a 10 kilo tonne PHA production unit at CJ's Fort Dodge, Iowa facility based on Metabolix's PHA technology. In certain embodiments, the genes introduced are from a heterologous organism. Exemplary catalysts include but are not limited to the following: Useful embodiments of the continuous biorefinery process are the production of biobased acrylic acids and related products derived by multiple tandem catalytic reactions from PHA biomass derived crotonic acid. The ruthenium-based organic catalysts which are now being manufactured by Materia (U.S. Pat. “There was no market. In other embodiments, methods of producing crotonic acid from a genetically modified polyhydroxyalkanoate (PHA) biomass include heating the biomass in the presence of a catalyst to release a crotonic acid component from the PHA, wherein the crotonic acid component yield is about 70% based on one gram of monomer per gram of polyhydroxyalkanoate reacting the crotonic acid to form a butyl crotonate ester, and hydrogenating the butyl crotonate ester to form two moles of butanol. This results in controlled decomposition of the PHA to the monomer components as a vapor phase that may then be recovered via condensation. In another embodiment, the invention pertains to a continuous biorefinery process for the production of acrylic acid from a genetically engineered PHA biomass comprising, culturing the genetically engineered PHA biomass to produce poly-3-hydroxypropionate, heating the poly-3-hydroxypropionate with a catalyst to produce acrylic acid, and recovering the acrylic acid. By continuing you agree to the use of cookies. Requirement for Restriction/Election for U.S. Appl. In 2015, Metabolix launched a-PHA from pilot production, and in 2016 is focused on securing initial and recurring sales across the target application spaces in anticipation of growing customer conversions and orders to baseload the new commercial capacity contemplated by the MOU with CJ.
As used herein, “pyrolysis liquids” are defined as a low viscosity fluid with up to 15-20% water, typically containing sugars, aldehydes, furans, ketones, alcohols, carboxylic acids and lignins Also known as bio-oil, this material is produced by pyrolysis, typically fast pyrolysis of biomass at a temperature that is sufficient to decompose at least a portion of the biomass into recoverable gases and liquids that may solidify on standing. Steinbuchel, “Polyhydroxyalkanoic Acids,” Biomaterials, MacMillan Publishers, London, pp. In another embodiment, it is also possible to subject the PHA chemicals generated from thermolysis directly to hydrogenation, esterification or amidation conditions to produce the corresponding diols, hydroxyl esters and amides. 5. Xanthos et al., “Solvolysis,” Frontiers in the Science and Technology of Polymer Recyclings, 425-436 (1998). Invitation to Pay Additonal Fees and Partial International Search for PCT/US2014/016122, “Process for Ultra-Pure Chemical Production From Biobased Raw Starting Materials”; dated Jul. Mango Materials has run this pilot facility since 2015. Suitable temperatures and duration for drying are determined for product purity and yield and can in some embodiments include low temperatures for removing water (such as between 25° C. and 150° C.) for an extended period of time or in other embodiments can include drying at a high temperature (e.g., above 450° C.) for a short duration of time. The multiple tandem catalysis reactions for transforming crotonic acid to butyl acrylate are shown below: Key to the above transformation is the conversion of the crotonic acid to the ester (metathesis catalysts can be inactivated by free carboxylic acids) and the use of propylene and not ethylene for the conversion of the butyl crotonate to butyl acrylate. Measurement of Thermal Degradation Products by Pyrolysis-Gas Chromatography-Mass Spectroscopy (Py-GC-MS).
