摘要： The present invention is directed to compositions which may undergo thermolysis to produce a higher purity acrylic acid product. In preferred embodiments of the present invention, the compositions comprise polypropiolactone and one or more active salts. The one or more active salts may catalyze thermolysis of the polypropiolactone so that the polymer depolymerizes into acrylic acid monomers. Certain concentrations of the one or more active salts result in higher purity acrylic acid products of thermolysis. In certain preferred embodiments, the one or more active salts include an acrylate group which may decompose under thermolysis to provide acrylic acid and thus decrease the concentration of undesirable contaminants in the acrylic acid product. In certain preferred embodiment, the one or more active salts comprise sodium acrylate.

摘要： Among other things, the present invention encompasses the applicant's recognition that epoxide carbonylation can be performed industrially utilizing syngas streams containing hydrogen, carbon monoxide and varying amounts carbon dioxide. Contrary to expectation, the epoxide carbonylation reaction proceeds selectively in the presence of these mixed gas streams and incorporates excess CO in the syngas stream into valuable chemical precursors, resulting in hydrogen streams substantially free of CO. This is economically and environmentally preferable to performing WSGR which releases the excess carbon as CO2. The integrated processes herein therefore provide improved carbon efficiency for processes based on coal or biomass gasification or steam methane reforming.

摘要： The present invention is directed to catalysts and processes for catalyzing two or more chemical reactions with a multifunctional catalyst in a reaction vessel. The processes include steps for introducing one or more reagents to a reaction vessel containing a multifunctional catalyst; contacting the one or more reagents with a first portion of the multifunctional catalyst to produce an intermediate; contacting the intermediate with a second portion of the multifunctional catalyst to produce a product; and removing the product from the reaction vessel. In certain embodiments, the multifunctional catalyst may have a first portion with carbonylation functionality for catalyzing the production of a beta-lactone intermediate from an epoxide reagent and a carbon monoxide reagent. In certain embodiments, the multifunctional catalyst may have a second portion with a functionality suitable for polymerization, co-polymerization, and/or modification of a beta-lactone intermediate. In preferred embodiments, the first portion and second portion are bonded to a heterogenous support.
