Efficient chemical recycling of poly(3-hydroxybutyrate) to crotonic acid via a sodium crotonate/stearyl alcohol catalytic system
Key Points
The study aims to demonstrate an efficient method for recycling poly(3-hydroxybutyrate) (PHB) into crotonic acid using a catalytic system.
Utilized a sodium crotonate/stearyl alcohol catalytic system for the depolymerization process.
Evaluated the efficiency of the recycling method under various conditions.
Achieved high yields of crotonic acid from PHB using the catalytic system.
Facilitated a closed-loop recycling process for bio-based polyesters.
Abstract
Efficient depolymerization of waste PHB to crotonic acid, enabled by NaCA/StOH catalysis, facilitates the closed-loop recycling of bio-based polyesters.
