摘要:A process for synthesizing 5-((2-methyl-1H-imidazol-1-yl)methyl)furan-2-carbaldehyde from a mixture comprising a carbohydrate, an alkali or alkaline-earth metal chloride, hydrochloric acid, water, an organic solvent, namely a water-insoluble polar aprotic solvent, and optionally a phase-transfer agent, proceeds via the formation of 5-(chloromethyl)furan-2-carbaldehyde, without isolating this synthesis intermediate. A process also synthesizes a compound of formula (III) below:from 5-((2-methyl-1H-imidazol-1-yl)methyl)furan-2-carbaldehyde.

权利人:WISCONSIN ALUMNI RES FOUND
摘要:A method of making polyesters and polyurethanes from biomass-derived polyols. The polyol is biomass-derived and has the structure:wherein dashed bonds are single or double bonds and R is selected from the group consisting of —OH and â•?O. Polyurethanes are made by reacting the polyol with a diisocyanate. Polyesters are made by reacting the polyol with a dicarboxylic acid.

标题 :System and method for synthesis of POSS-starch derivatives as effective fillers for developing high performance composites

摘要:According to an embodiment, natural polymers will be used to enhance the biodegradability of nanocomposites, increase potential use of sustainable polymer matrices, improve the interlaminar fracture toughness of graphite/epoxy composites and attain complete nanoparticle dispersion through covalent bonding of nanoparticles and natural polymers. The starch derivatives containing POSS (polyhedral silsesquioxane) were synthesized by reacting natural polymer with different POSS molecules in a solvent in presence of a catalyst. Interlaminar fracture toughness testing results from the epoxy based nanocomposites containing 3, 5, 7, and 10 wt % POSS modified natural polymer in the interlaminar area are presented. The biodegradability of the composites is expected to improve through the incorporation of the natural polymer derivatives.

摘要:According to an embodiment, a method for grafting POSS (polyhedral silsesquioxane) nanomaterial to graphene oxide is described for use in preparation of high performance composite materials. In another embodiment, amine functionalized graphene oxide may be particularly suitable. In this embodiment, POSS molecules grafted to amine functionalized graphene oxide are synthesized by reacting graphene oxide with different POSS molecules. The amine functionalized graphene oxide may be dissolved in a solvent and the reaction may include the presence of a catalyst. The resultant POSS grafted graphene oxide/POSS grafted amine functionalized graphene oxide may be mixed with a resin (epoxy) in a masterbatch. The masterbatch may then be packaged and sold. The masterbatch material may then be introduced into the interlaminar area of graphite/epoxy composites. Biodegradability and interlaminar fracture toughness testing results from the use of epoxy based nanocomposites containing POSS modified graphene oxide polymer are expected to improve.

摘要:The present invention relates to a process for producing a surface-functionalized molding (oF) having a functionalized surface (fO). In this process a surface (O) of a molding (F) is brought into contact with a dienophile-containing solution (dL). The surface (O) comprises a polyamide (P) which comprises furan units. These furan units are able to react with the at least one dienophile present in the dienophile-containing solution (dL) to give the surface-functionalized molding (oF) having the functionalized surface (fO).

标题:Chemical synthesis of conducting polypyrrole
发明人：WALKER JOHN A; WITUCKI EDWARD F; WARREN LESLIE F
权利人:ROCKWELL INTERNATIONAL CORP
摘要:Production of electrically conductive polypyrrole of enhanced stability by treating a liquid pyrrole with a solution of a strong oxidant, capable of oxidizing pyrrole to a pyrrole polymer, and oxidizing the pyrrole by such strong oxidant in the presence of a relatively large organic dopant anion, and precipitating a conductive polypyrrole. The strong oxidant, e.g., Fe3+ ion, and dopant anion, which can be an alkyl or aryl sulfonate, e.g., methylbenzenesulfonate, or a perfluorinated carboxylate, e.g., trifluoroacetate, anion, can be derived from a single compound, e.g., the anion serving as dopant for the polypyrrole.
