Synthesis of functionalized polyisobutylenes
Disclosed is a simplified process for formation of polyisobutylene functionalized with at least one terminal primary or secondary alcohol. The process comprises subjecting an olefin functional polyisobutylene, butyl rubber, or mixtures thereof to ozonation and reduction thereby forming mono-alcohol and diol functional polyisobutylene. The formed functional polyisobutylenes can serve as precursors for many other functionalized polyisobutylenes including urethane polyisobutylenes, urethane polyisobutylenes capped with (meth)acrylate functions, and (meth)acrylate capped polyisobutylenes.
Process for the sustainable production of acrylic acid
A process for the production of organic acids having at least three carbon atoms comprises the steps of forming an amount of carbon monoxide and reacting the amount of carbon monoxide with an amount of an unsaturated hydrocarbon. The reaction is preferably carried out in the presence of a supported palladium catalyst, a strong acid, and a phosphine. In some embodiments, the unsaturated hydrocarbon is one of acetylene and methylacetylene, and the organic acid is one of acrylic acid and methyl acrylic acid. The reacting step is preferably performed with carbon monoxide produced from carbon dioxide.
