Mafotokozedwe Akatundu
DEG imapangidwa ndi gawo la hydrolysis ya ethylene oxide. Kutengera ndi momwe zinthu ziliri, kuchuluka kwa DEG ndi ma glycol ogwirizana amapangidwa. Chotsatira chake ndi mamolekyu awiri a ethylene glycol ophatikizidwa ndi chomangira cha ether.
"Diethylene glycol imatengedwa ngati co-product ndi ethylene glycol (MEG) ndi triethylene glycol. Makampani nthawi zambiri amagwira ntchito kuti apititse patsogolo kupanga MEG. Ethylene glycol ndi gawo lalikulu kwambiri la mankhwala a glycol mu ntchito zosiyanasiyana. Kupezeka kwa DEG zidzadalira kufunikira kwa zinthu zomwe zimachokera ku chinthu choyambirira, ethylene glycol, osati pa zofuna za msika wa DEG."

Kugwiritsa ntchito
| Amagwiritsidwa ntchito ngati mpweya dehydrating wothandizira ndi aromatics m'zigawo zosungunulira, amagwiritsidwanso ntchito ngati lubricant nsalu, softener ndi kumaliza wothandizira, komanso plasticizer, humidifier, sizing agent, nitrocellulose, utomoni ndi zosungunulira mafuta. |
Diethylene glycol imagwiritsidwa ntchito popanga utomoni wa polyester wodzaza ndi unsaturated, polyurethanes, ndi plasticizers.DEG imagwiritsidwa ntchito ngati chomangira cha organic synthesis, mwachitsanzo, morpholine ndi 1,4-dioxane. Ndiwosungunulira wa nitrocellulose, utomoni, utoto, mafuta, ndi zinthu zina zachilengedwe. Ndiwosungunulira mufodya, kota, inki yosindikizira, ndi guluu. Ndiwonso gawo lamadzimadzi a brake, mafuta opaka, zochotsa pamapepala, zopangira chifunga ndi utsi, ndi mafuta otenthetsera/kuphika. mafuta odzola, deodorants), DEG nthawi zambiri imasinthidwa ndi ma ether osankhidwa a diethylene glycol. Njira yochepetsera ya diethylene glycol ingagwiritsidwenso ntchito ngati cryoprotectant; Komabe, ethylene glycol imagwiritsidwa ntchito kwambiri. Ambiri a ethylene glycol antifreeze ali ndi ochepa peresenti ya diethylene glycol, omwe amapezeka ngati mankhwala opangidwa ndi ethylene glycol.
Ubwino
Ubwino wazinthu, kuchuluka kokwanira, kuperekera kogwira mtima, ntchito yabwino kwambiri Imakhala ndi mwayi wopitilira amine wofanana, ethanolamine, chifukwa kuchuluka kwakukulu kungagwiritsidwe ntchito pakuwonongeka komweko. Izi zimathandiza oyenga kutsuka hydrogen sulfide pamlingo wocheperako wozungulira wa amine osagwiritsa ntchito mphamvu zonse.
