Abstract
Processes and methods for making biobased acrylic acid products including acrylic acid, acrylic acid oligomers, acrylic acid esters, acrylic acid polymers and articles from renewable carbon resources are described herein.
Claims27
A process for production of a biobased acrylic acid product, comprising:
- a) combining a genetically engineered host biomass comprising poly-3-hydroxypropionate, a heat transfer fluid having a boiling temperature, and optionally a catalyst to obtain a biomass mixture;
- and
- b) heating the biomass mixture at a heating temperature to convert the poly-3-hydroxypropionate to an acrylic acid product;
- wherein a yield of the acrylic acid product is at least 80% and the biobased carbon content of the acrylic acid product is at least 90%.
1 more element
A process for production of a biobased butyl acrylic acid ester product, comprising
- a) combining a genetically engineered host biomass comprising poly-3-hydroxypropionate, n-butanol and a catalyst to produce a biomass mixture;
- b) heating the biomass mixture with the n-butanol and catalyst to reflux for 15-24 hours;
- and
- c) converting the poly-3-hydroxypropionate to a butyl acrylic acid ester product;
- wherein a yield of the acrylic acid ester product is at least 80% and the biobased carbon content of the acrylic acid product is at least 40%.
