Iimveliso
Isopropyl utywala CAS No. 67-63-0
Ingcaciso yeMveliso
I-DEG iveliswa yinxenye ye-hydrolysis ye-ethylene oxide. Ngokuxhomekeke kwiimeko, iimali ezihlukeneyo ze-DEG kunye ne-glycols ezinxulumene nazo ziveliswa. Imveliso ebangelwa zi-amolekyu ezimbini ze-ethylene glycol ezidityaniswe yi-ether bond.
"I-Diethylene glycol ithathwa njenge-co-product kunye ne-ethylene glycol (MEG) kunye ne-triethylene glycol. Ishishini ngokubanzi lisebenza ukwandisa imveliso ye-MEG. I-Ethylene glycol yiyona nto inkulu kakhulu yeemveliso ze-glycol kwizicelo ezahlukeneyo. Ukufumaneka kwe-DEG iya kuxhomekeka kwimfuno yezinto eziphuma kwimveliso yokuqala, i-ethylene glycol, kuneemfuno zemarike zeDEG.

Isicelo
| Isetyenziswa njenge-emulsifier, i-humectant, i-humidifier, i-thickener, i-agent yokulinganisa i-pH |
I-Diethylene glycol isetyenziselwa ukuveliswa kwe-polyester egcweleyo kunye ne-unsaturated resins, i-polyurethanes, kunye ne-plasticizers.DEG isetyenziswe njengebhloko yokwakha kwi-organic synthesis, umzekelo we-morpholine kunye ne-1,4-dioxane. Isisinyibilikisi se-nitrocellulose, iresin, idayi, ioyile, kunye nezinye iikhompawundi eziphilayo. Yinto ethambisayo kwicuba, isikhokho, inki yokushicilela, kunye neglu. Ikwayinxalenye yebrake fluid, lubricants, strippers wallpaper, inkungu eyenziweyo kunye nezisombululo zenkungu, kunye namafutha okufudumeza/okupheka. izinto zokuthambisa, iideodorants), iDEG idla ngokutshintshwa yi-diethylene glycol ethers ekhethiweyo. Isisombululo esihlanjululweyo se-diethylene glycol sinokusetyenziswa njenge-cryoprotectant; nangona kunjalo, i-ethylene glycol isetyenziswa kakhulu. Uninzi lwe-ethylene glycol antifreeze iqulethe ipesenti ezimbalwa ze-diethylene glycol, ekhoyo njenge-byproduct yemveliso ye-ethylene glycol.
Inzuzo
Umgangatho wemveliso, ubungakanani obaneleyo, unikezelo olusebenzayo, umgangatho ophezulu wenkonzo Inenzuzo ngaphezu kwe-amine efanayo, i-ethanolamine, ekubeni i-concentration ephezulu ingasetyenziselwa ukubola okufanayo. Oku kuvumela abasulungeki ukuba bakhuhle ihydrogen sulfide ngesantya esisezantsi se-amine esijikelezayo sisebenzisa amandla angaphantsi ngokubanzi.
