Vinylene Carbonate (VC)

Mature Chemical Chain, Green Process for VC Production: Safe and Reliable.

Vinylene Carbonate (VC) Technology Introduction

CEC Synthesis: EC reacts with chlorine in a photolysis tower under UV catalysis, followed by neutralization with liquid alkali. Residual chlorine and HCl are stripped using nitrogen, with off-gas sent to an HCl absorption tower.

VC Synthesis: Using DMC as a solvent and triethylamine as a catalyst, the reaction eliminates hydrogen chloride. After centrifugal filtration removes solid salts, the filtrate passes through desolvation, crude distillation, rectification, and crystallization units to yield qualified product.

Company Profile: DODGEN leads in high-purity Vinylene Carbonate manufacturing. Specializing in VC and EC synthesis, we provide advanced technology and expertise to ensure high-purity output for battery electrolytes and industrial applications.
