High-efficiency purification and polymerization — from pilot to commercial scale. Explore our current portfolio.
Meso-lactide <5 wt.% and L-lactide >99.5 wt.% via integrated reactive + divided-wall distillation. Residual acidity <2 meq/kg; PLA Mw >200k.
Continuous production of ultrapure glycolide via controlled pre-polymerization, reactive-distillation depolymerization, and melt-crystallization polish.
Four-stage high-Mw polymerization with efficient devolatilization; optional supercritical CO₂ for heat/mass-transfer and low residuals.
Refined divided-wall distillation delivering ≥99.98 wt.% mPDA with excellent isomer rejection and stable operability.
Two divided-wall columns followed by crystallization for deep impurity removal and high-purity intermediates.
Absorber with pump-around cooling → divided-wall refining column with dual reboilers & side-draw; demonstrated >50% energy savings.
Horizontal perforated static-mixing reactor housed in a vertical vessel for superior disengagement and recovery; excellent thermal stability.
Three-column train: aniline recovery → CHA ≥99.7 wt.% → DWC with side-draw for DCHA ≥99.8 wt.%.
Process know-how under development for 5-hydroxymethylfurfural (HMF) from renewable carbohydrate feedstocks, with focus on route evaluation and process integration.
