Industrial technologies for lactide/glycolide monomers, PLA/PGA polymerization, aromatics purification, and energy-efficient refining.
L-lactide ≥ 99.5%; residual acidity < 2 meq/kg; PLA Mw > 200k.
DWC-based separation consistently achieving ≥ 99.98 wt.% purity; commercial scale (2024).
PLA/PGA/PCL polymerization with efficient devolatilization; low residuals and high throughput.
Dual-reboiler refining column; >50% energy savings demonstrated at commercial scale.
Horizontal perforated static-mixing reactor in a vertical vessel; excellent disengagement and thermal stability.
Continuous production of ultrapure glycolide via pre-polymerization, reactive-distillation depolymerization, and melt-crystallization polish.
