Abstract: Processes and systems for producing isomeric mixtures of aromatic amine monomers from aromatic feeds. An example process for producing isomeric mixtures of aromatic amine monomers from aromatic feeds may include nitrating at least a portion of an aromatic feed to produce a mixture of nitrated aromatic compounds. The example process may further include hydrogenating at least a portion of the nitrated aromatic compounds to produce an isomeric mixture of aromatic amine monomers. The example process may further include processing the isomeric mixture of aromatic amine monomers to form a product selected from an aromatic compound with a different functional group than the aromatic amine monomers, a polymerized product, or a reaction product of the aromatic amine monomers and H2S.

Abstract: Methods for preparing mixed polyamides, polyimides and polyamideimides under hydrothermal polymerization conditions are provided. The methods are based on suitable mixtures of poly carboxylic acids, poly carboxylic dianhydrides or poly carboxylic acid chloride anhydrides and polyamines and provide routes to low cost structural polymers useful in, for example, infrastructure applications.

Abstract: A frozen material prevention system for preventing a freezable material in a fluid flow from freezing and accumulating frozen material in a flow path, including, a surface configured to interact with a freezable-material-miscible (FMM) liquid to retain the FMM liquid to the surface. The system can include the FMM liquid. The FMM liquid can be configured to absorb the freezable material to prevent freezing and accumulation of frozen material on the surface.

Abstract: Systems and methods are provided for ozonolysis of polycyclic aromatic hydrocarbons (PAHs) in a liquid CO2 reaction environment. It has been unexpectedly discovered that oxygen-containing functional groups can be added to PAH substrates while substantially avoiding combustion reactions and while reducing or minimizing formation of energetic intermediates. Because the formation of energetic intermediates is minimal, the ozonolysis can be performed at temperatures near ambient (e.g., between −10° C. and 50° C.) while still achieving a satisfactory safety profile. In various aspects, ozonolysis can occur while forming a reduced or minimized amount of water, such as forming substantially no water in the reaction environment.
