Kulumikizana kwa Ethylene Glycol ndi Dimethyl Carbonate
Njira iyi ingagawidwe m'magawo awiri akuluakulu: choyamba, carbon dioxide ndi ethylene oxide zimachitapo kanthu pansi pa chothandizira kupanga ethylene carbonate, yomwe kenako imachitapo kanthu ndi methanol yowonjezera kupanga ethylene glycol ndi dimethyl carbonate. Ubwino wa njira iyi ndi monga:
Kugwiritsa ntchito CO₂, chinthu chochokera ku ethylene oxide, kuti achepetse ndalama zopangira zinthu zopangira ndi mpweya woipa womwe umawononga chilengedwe.
Ethylene carbonate imagwira ntchito bwino kwambiri, imagwira ntchito ngati mankhwala ogwiritsidwa ntchito m'njira zosiyanasiyana ndipo imasungidwa bwino komanso imayendetsedwa bwino. Itha kugwiritsidwa ntchito ngati chopangira chapakati pakupanga ethylene glycol kapena kugulitsidwa mwachindunji ngati chinthu chomalizidwa, kupewa kugwiritsa ntchito mphamvu zambiri komanso mavuto okhudzana ndi kuipitsidwa komwe kumachitika chifukwa cha madzi ngati chinthu chopangira.
Chopangidwa kuchokera pamenepo, dimethyl carbonate, chili ndi phindu lalikulu ndipo ndi mankhwala oyambira omwe amagwiritsidwa ntchito kwambiri.
Kuchuluka kwa magwiritsidwe ntchito a atomu kumafika 100%, zomwe zimaika m'gulu la njira yopangira zinthu zoyera "zopanda kutulutsa mpweya".
