Txoj kev tsim khoom
- Kev tsim cov propylene carbonate (PC) los ntawm txoj kev propylene oxide (PO4)
Cov khoom siv raw carbon dioxide thiab propylene oxide raug nias kom ua rau propylene carbonate;
- Kev tsim cov propylene carbonate (PC) los ntawm cov txheej txheem urea
Urea reacts nrog propylene glycol los tsim propylene carbonate thiab ammonia. - Kev tsim cov dimethyl carbonate (DMC) los ntawm kev pauv ester
Nyob rau hauv qhov kev ua ntawm catalyst, methanol thiab propylene carbonate yog tsim los tsim dimethyl carbonate thiab 1,2-propanediol.
