إيزوسوربيد الأيزوسوربيد (ISO)
Continuous, low-cost production of polymerization-grade isosorbide is achieved through unique reaction and separation technologies.
Isosorbide (ISO) Process Technology Introduction
Leveraging proprietary reaction and separation equipment, DODGEN has developed a continuous production technology for high-quality, polymerization-grade isosorbide via reactive distillation and melt crystallization purification.
Key Performance Indicators:
- High Yield & Purity: Achieves a product yield of over 85% with purity exceeding 99%.
- Efficiency: Features recyclable catalysts, low equipment investment (CAPEX), and reduced energy consumption.
- Progress: The pilot-scale process development for PBIST has been successfully completed.
This innovative process is designed to replace outdated batch production methods using concentrated sulfuric acid, which suffer from low conversion efficiency and high energy consumption—bottlenecks that have historically hindered large-scale industrialization. Consequently, DODGEN’s efficient, catalytic continuous process addresses the urgent industry need for modernization. Recently, research has focused on utilizing isosorbide as a comonomer to modify existing polymers, significantly enhancing their physical properties and polyester performance.
