Process for the purification of alkylene carbonate |
摘要 |
Provided herein is a process for producing alkylene carbonates of ultra-high purity. According to the present invention, certain stages of traditional distillation of alkylene carbonate distillation are replaced by carbon treatment. Alkylene carbonates produced according to the invention have a color of less than 25 (Pt-Co), and are suitable for uses requiring ultra-pure alkylene carbonates. |
