Preparation of vegetable oil-based monomers for use in thermosetting resins
The present embodiments herein generally relate to thermoset resins that are derived from vegetable oil based sources, including fibrous plant sources. The utilization of plant based oil as starting materials makes the technology a green alternative to currently available solutions. This, coupled with the novel synthetic methods that are utilized, results in a transformation of the plant based oils into useful, durable, and resilient thermoset resins.
CONTINUOUS CARBONYLATION PROCESSES
Provided are processes for monitoring and maintaining continuous carbonylation of epoxides or lactones. Processes include measuring parameters affecting the rate of the carbonylation reaction and adding supplemental replacement catalyst replacement components to maintain a constant rate of carbonylation.
