Imikhiqizo
I-Organic Chemicals Solvent Diethylene Glycol Product CAS No 111-46-6 Transparent Liquid
Incazelo Yomkhiqizo
I-DEG ikhiqizwa ingxenye ye-hydrolysis ye-ethylene oxide. Ngokuya ngezimo, amanani ahlukahlukene we-DEG nama-glycol ahlobene akhiqizwa. Umkhiqizo owumphumela ungama-molecule amabili e-ethylene glycol ahlanganiswe isibopho se-ether.
"I-Diethylene glycol itholakala njengomkhiqizo ohlangene ne-ethylene glycol (MEG) ne-triethylene glycol. Imboni ngokuvamile isebenza ukuze ikhulise ukukhiqizwa kwe-MEG. I-Ethylene glycol ingumthamo omkhulu kakhulu wemikhiqizo ye-glycol ekusetshenzisweni okuhlukahlukene. Ukutholakala kwe-DEG izoncika ekufuneni kokuphuma kokunye komkhiqizo oyinhloko, i-ethylene glycol, kunezimfuneko zemakethe ze-DEG."

Isicelo
| Isetshenziswa njenge-ejenti eqeda amanzi emzimbeni kanye ne-aromatics extraction solvent, iphinde isetshenziswe njenge-lubricant yendwangu, i-softener ne-ejenti yokuqedela, kanye ne-plasticizer, humidifier, i-ejenti yokulinganisa, i-nitrocellulose, i-resin ne-solvent yamafutha. |
I-Diethylene glycol isetshenziswa ekukhiqizeni ama-polyester agcwele futhi angasetshenzisiwe, ama-polyurethanes, nama-plasticizers.DEG isetshenziswa njengesakhiwo se-organic synthesis, isb i-morpholine ne-1,4-dioxane. Kuyi-solvent ye-nitrocellulose, ama-resin, odayi, amafutha, nezinye izinhlanganisela eziphilayo. Iyathobisa ugwayi, ukhokho, uyinki wokuphrinta, kanye neglue.Iphinde ibe ingxenye kuketshezi lwamabhuleki, okothambisa, izihluthulelo zamaphephadonga, izisombululo zenkungu nenkungu yokwenziwa, kanye nophethiloli wokushisa/wokupheka. Emikhiqizweni yokunakekela umuntu (isb. ukhilimu wesikhumba kanye izinto zokuthambisa, iziqedaphunga), i-DEG ivamise ukuthathelwa indawo ama-ether e-diethylene glycol akhethiwe. Isixazululo esincibilikisiwe se-diethylene glycol singasetshenziswa futhi njenge-cryoprotectant; Nokho, i-ethylene glycol isetshenziswa kakhulu. Iningi le-ethylene glycol antifreeze liqukethe amaphesenti ambalwa e-diethylene glycol, akhona njenge-byproduct yokukhiqizwa kwe-ethylene glycol.
Inzuzo
Izinga lomkhiqizo, inani elanele, ukulethwa okuphumelelayo, izinga eliphezulu lesevisi Inenzuzo kune-amine efanayo, i-ethanolamine, ngokuthi ukugxilisa okuphezulu kungase kusetshenziselwe amandla afanayo okugqwala. Lokhu kuvumela abacwengi ukuthi bakhuhle i-hydrogen sulfide ngenani eliphansi le-amine elijikelezayo ngokusetshenziswa kwamandla sekukonke.
