Definitions

  • This disclosure is related to the field of renewable resourced materials. Specifically, the disclosure relates to solvents, intermediates and other chemical products that are produced from renewable resources and are useful for displacing those materials that are currently derived from petroleum feedstocks. Of particular interest are solvents, monomers, polymers and additives that can be used in the field of paints and coatings, especially automotive coatings.
  • An example of this is polytrimethylene terephthalate.
  • the trimethylene portion of the molecule can be derived from 1 ,3-propane diol that is derived from bio-sources.
  • the terephthalic acid comes from a petroleum source, so the polyester is only partially derived from renewable resources.
  • an isocyanate or polyisocyanate compound wherein greater than 10 percent the carbon atoms of said isocyanate or said polyisocyanate compound are derived from renewable resources.
  • a monomer wherein the monomer is selected from the group consisting of bio-acrylic acid, bio-methacrylic acid, bio-alkyl acrylates, bio-alkyl methacrylates, bio-acrylamide, bio-methacrylamide, bio- acrylonitrile, bio-methacrylonitrile and a combination thereof; and wherein at least of portion of the carbon atoms of said monomer are derived from renewable resources.
  • a third disclosure is a polymer formed by the polymerization of a monomer mixture comprising at least one monomer wherein at least one monomer is derived from a renewable resource.
  • Another disclosure is a method of forming a polymer comprising;
  • a solvent and monomer mixture wherein the monomers are chosen from the group consisting of bio-acrylic acid, bio-methacrylic acid, bio-alkyl acrylates, bio-alkyl methacrylates, bio-acrylamide, bio- methacrylamide, bio-acrylonitrile, bio-methacrylonitrile and a combination thereof; wherein; a) the acrylate potion of said bio-alkyl acrylates or said bio- alkyl methacrylates is a substituted or unsubstituted alkyl group having in the range of from 1 to 20 carbon atoms; and b) the solvent and the monomer is derived from renewable resources;
  • a solvent derived from renewable resources wherein said solvent is the reaction product of two or more components, wherein at least one of said components is derived from renewable resources.
  • Suitable examples for the transformation of bio-mass include, for example, chemical processes, biological fermentation; anaerobic yeast, fungal or bacterial processes; aerobic yeast, fungal or bacterial process; and chemical enzyme process.
  • the components may be produced in their pure form or they may require a step or steps of isolation and/or purification prior to use. While the components may be capable of being derived from petroleum feedstock, the phrases are intended to exclude components that specifically derive 100 percent of their carbon atoms from petroleum feedstock.
  • bio- placed as a prefix means that at least a portion of the carbon atoms of the component are derived from a renewable resource. Also included within this definition are those components that are produced naturally in plants. For example, bio-limonene and bio-isobomyl alcohol can be harvested from various plants. While the component may be capable of being derived from petroleum feedstock, the prefix is intended to exclude those components that specifically derive all of their carbon atoms from petroleum feedstock.
  • bio-ethanol means ethanol that is formed from renewable resources. All of the carbon atoms in bio-ethanol derived from, for example, fermentation, are from renewable resources.
  • a component is the reaction product of two or more intermediates, then to be described as a bio-component, at least a portion of the carbon atoms that form a part of the final component must be derived from biomass sources. Catalysts, solvents or other adjuvants that are used to facilitate the reaction, but do not form a part of the final bio-component, do not necessarily need to be derived from biomass.
  • a bio-component derives all of its carbon content from renewable resources.
  • a bio-monomer produced from the esterification reaction between bio-acrylic acid and bio- ethanol to form bio-ethyl acrylate derives 100 percent of it carbon from renewable resources.
  • a bio-component derives greater than 1 percent of its carbon from renewable resources.
  • a bio- monomer produced from the esterification reaction between petroleum based acrylic acid (containing 3 carbon atoms) and bio-ethanol (containing 2 carbon atoms) to form bio-ethyl acrylate derives 40 percent of it carbon from renewable resources.
  • a bio-component derives greater than 10 percent of its carbon from renewable resources.
  • a bio-component derives greater than 20 percent of its carbon from renewable resources.
  • bio-based components differ from petroleum-based components. Petroleum-based components do not have the carbon 14 isotope present. Bio-based products have an identifiable amount of carbon 14. Carbon 14 is present in bio-mass as a result of carbon dioxide that is formed when nitrogen is struck by an ultra-violet light produced neutron, causing the nitrogen to lose a proton and form carbon of molecular weight 14 which is immediately oxidized to carbon dioxide. This radioactive isotope represents a small but measurable fraction of atmospheric carbon. Atmospheric carbon dioxide is cycled by green plants to make organic molecules during the process known as photosynthesis. The cycle is completed when the green plants or other forms of life metabolize the organic molecules producing carbon dioxide which is released back to the atmosphere.
  • the bio-based content of materials can be determined.
  • ASTM International formally known as the American Society for Testing and Materials, has established a standard method for assessing the bio-based content of materials.
  • the ASTM method is designated ASTM- D6866.
  • the application of ASTM-D6866 to derive a "bio-based content" is built on the same concepts as radiocarbon dating, but without use of the age equations.
  • the analysis is performed by deriving a ratio of the amount of radiocarbon (carbon 14) in an unknown sample to that of a modem reference standard. The ratio is reported as a percentage with the units "pMC" (percent modern carbon). If the material being analyzed is a mixture of present day radiocarbon and fossil carbon (containing no carbon 14), then the pMC value obtained correlates directly to the amount of biomass material present in the sample.
  • the modern reference standard used in radiocarbon dating is a NIST (National Institute of Standards and Technology) standard with a known radiocarbon content equivalent approximately to the year AD 1950.
  • AD 1950 was chosen since it represented a time prior to thermo-nuclear weapons testing which introduced large amounts of excess radiocarbon into the atmosphere with each explosion (termed “bomb carbon”).
  • the AD 1950 reference represents 100 pMC. Bomb carbon in the atmosphere reached almost twice normal levels in 1963 at the peak of testing and prior to the treaty halting the testing. Its distribution within the atmosphere has been approximated since its appearance, showing values that are greater than 100 pMC for plants and animals living since AD 1950. It's gradually decreased over time with today's value being near 107.5 pMC. This means that a fresh biomass material such as corn could give a radiocarbon signature near 107.5 pMC.

  • the bio-solvent may not be directly available from the renewable resource.
  • the component that can be derived from the renewable resource may need to undergo one or more chemical reactions and/or purification steps to form the desired bio-solvent.
