Iimveliso

I-Organic Chemicals Solvent Diethylene Glycol Product CAS No 111-46-6 Transparent Liquid

Inkcazelo emfutshane:

I-Diethylene glycol (DEG) i-organic compound kunye ne-formula (HOCH2CH2) 2O. Lulwelo olungenambala, alunavumba, kunye nehygroscopic enencasa eswiti. Yi-carbon dimer emine ye-ethylene glycol. I-miscible emanzini, utywala, i-ether, i-acetone, kunye ne-ethylene glycol.DEG i-solvent esetyenziswa ngokubanzi.Inokuba yinto engcolileyo kwimveliso yabathengi; oku kukhokelele kwizibetho ezininzi zetyhefu ukususela ekuqaleni kwenkulungwane yama-20.

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-agent yokuphelisa amanzi emzimbeni kunye ne-aromatics extraction solvent, ekwasetyenziswa njenge-lubricant ye-textile, i-softener kunye ne-ejenti yokugqiba, kunye ne-plasticizer, i-humidifier, i-agent ye-agent, i-nitrocellulose, i-resin kunye ne-solvent yegrisi.

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.
