Kubatanidzwa kwe Ethylene Glycol uye Dimethyl Carbonate
Nzira iyi inogona kukamurwa kuita matanho maviri makuru: chekutanga, kabhoni diokisijeni ne ethylene oxide zvinosangana pasi pe catalyst kugadzira ethylene carbonate, iyo inobva yasangana ne methanol yakawedzerwa kugadzira ethylene glycol ne dimethyl carbonate. Zvakanakira nzira iyi zvinosanganisira:
Kushandiswa kweCO₂, chinhu chinobva mukugadzirwa kwe ethylene oxide, kuderedza mitengo yezvinhu zvisina kugadzirwa uye kuburitswa kwemhepo inokonzera kudziya kwepasi.
Ethylene carbonate ine basa rakanaka kwazvo, inoshanda semushonga wemakemikari unosiyana-siyana, inochengeterwa uye inotakurwa zvakachengeteka. Inogona kushandiswa senzira yepakati yekugadzira ethylene glycol kana kutengeswa zvakananga semushonga wapera, kudzivirira kushandiswa kwesimba rakawanda uye matambudziko ekusvibiswa anokonzerwa nemvura sezvinhu zvisina kucheneswa.
Chinhu chinobva pachinhu ichi, dimethyl carbonate, chine kukosha kwakanyanya uye chinhu chinoshandiswa zvakanyanya mumakemikari.
Mwero wekushandiswa kweatomu unosvika 100%, zvichiiisa muchikamu che "zero-emission" clean production process.
