Provided are methods of producing polyamides from beta-lactones. The polyamides include bio-based polyamides that may be obtained, either in part or completely, from renewable sources.

Polyamides, and methods of producing thereof

Provided herein are reactor systems and processes for producing organic acids directly from beta-lactones. Such reactor systems and processes involve the use of a heterogeneous catalyst, such as a zeolite at vapor phase conditions. The reactor systems and processes may use a fixed bed, moving bed or fluidized contacting zone as reactor configurations.

Systems and processes for producing organic acids directly from beta-lactones

Disclosed are compositions, systems and methods related to a polypropiolactone composition comprising polypropiolactone polymers. Such polymers include polypropiolactone chains of Formula (I): where n is an integer from 10 to about 1,000 and Y is either —H or a cation.

Systems and processes for polymer production

Provided herein are methods of producing acrylic acid from beta-propiolactone. Such methods may involve the use of a heterogeneous catalyst, such as a zeolite.

Acrylic acid, and methods of producing thereof

The present invention is directed to processes for producing isocyanates and isocyanate derivatives from epoxide and carbon monoxide reagents. In preferred embodiments, the processes include a step for providing carbonylation of an epoxide reagent with a carbon monoxide reagent to produce a beta-lactone intermediate. In certain preferred embodiments, further carbonylation of a beta-lactone intermediate produces a succinic anhydride intermediate. The processes of the present invention include steps for rearranging beta-lactone intermediates and/or succinic anhydride intermediates to produce isocyanate products and/or isocyanate derivatives. In certain preferred embodiments, the isocyanate products may be copolymerized with polyol oligomers to provide polyurethane products.

The integrated processes herein provide improved carbon efficiency for processes based on coal or biomass gasification or steam methane reforming. Provided are also ethylene oxide carbonylation products such as beta-propiolactone and succinic anhydride having a bio-based content between 0% and 100%, and methods for producing and analyzing the same.

Integrated methods for chemical synthesis

Provided are methods of producing sulfur- and phosphorus-containing polymers from beta-lactones. The sulfur- and phosphorus-containing polymers include bio-based sulfur- and phosphorus-containing polymers that may be obtained from renewable sources.

Phosphorus-containing polymers, and methods of producing thereof

The present invention provides novel solutions to the problem of recycling carbonylation catalysts in epoxide carbonylation processes. The inventive methods are characterized in that the catalyst is recovered in a form other than as active catalyst. In some embodiments, catalyst components are removed selectively from the carbonylation product stream in two or more processing steps. One or more of these separated catalyst components are then utilized to regenerate active catalyst which is utilized during another time interval to feed a continuous carbonylation reactor.

Catalyst recycle methods

Provided herein are methods and systems for producing biodegradable beta-propiolactone-based polyester polymers from renewable EO and CO on an industrial scale.
