Alaab-qeybiyaha Dahabka ah ee Kiimikada ah ee dareere ah DMC/Dimethyl Carbonate
Hordhac Badeecada
Dimethyl carbonate / DMC waa iskudhis muhiim ah oo dabiici ah oo leh qaacido kiimiko ah oo C3H6O3 ah iyo miisaan molecular ah oo ah 90.08g/mol. Waa dareere aan midab lahayn oo hufan, oo ku dhawaad aan ku milmi karin biyaha, wuxuuna leeyahay milmi sare oo ku jira dareerayaasha dabiiciga ah sida ethanol, benzene iyo acetone. Dimethyl carbonate wuxuu leeyahay astaamo sun ah oo hooseeya, isbeddel yar, si fiican u burburi kara oo aan waxyeello u lahayn deegaanka, sidaa darteed si weyn ayaa loogu isticmaalaa warshadaha kiimikada, daawada, cuntada iyo agabka.

Codsiga
1. Warshadaha kiimikada, dimethyl carbonate waxaa inta badan loo isticmaalaa isku-darka polycarbonate-ka waxqabadka sare leh, polyurethane-ka, aliphatic carbonate iyo agab kale oo muhiim ah oo polymer ah.
2. Dhinaca daawada, dimethyl carbonate waa dareere dabiici ah oo ammaan ah oo wax ku ool ah, kaas oo inta badan loo isticmaalo diyaarinta daawooyinka, suuxinta caafimaadka, dhiigga macmalka ah iyo alaabada kale ee caafimaadka.
3. Warshadaha cuntada, oo ah wax lagu daro cuntada dabiiciga ah, dimethyl carbonate waxaa si weyn loogu isticmaalaa xawaashka, waxyaabaha caanaha laga sameeyo, cabitaannada iyo cuntooyinka kale si kor loogu qaado caraf udgoonka iyo dhadhanka cuntada.
Intaa waxaa dheer, dimethyl carbonate waxaa sidoo kale loo isticmaali karaa sidii wakiil nadiifin iyo surfactant, oo si weyn loogu isticmaalo baabuurta, hawada sare, elektarooniga, dawooyinka, dahaarka iyo qaybaha kale ee warshadaha. Gunaanadkii, dimethyl carbonate waa isku-dhis dabiici ah oo badan oo shaqeynaya, ammaan ah oo deegaanka u fiican, kaas oo leh rajo ballaaran oo ku saabsan adeegsigiisa meelo badan.
