Dab tsi yog ethylene glycol (piv txwv) CAS 107-21-1?
Ob deg thiab piv txwv li koom nrog tsev neeg glycol, uas yog tus cwj pwm los ntawm lub xub ntiag ntawm ob lub hydroxyl (-oh) pawg.Ethylene glycol piv txwvMuaj ib tus qauv yooj yim nrog ob daim ntawv cog lus hauv atoms, txhua tus sib khi rau cov pab pawg hydroxyl, nrog tshuaj C2h6o2. Nws yog ib qho tsis muaj kob, tsis muaj ntxhiab, thiab cov kua dej khov rau ntawm chav sov, nrog lub siab bub point ntawm -12. 9 degree.
Cov ethirene glycolene glycol yog ib qho tsis muaj kob, kua tsis muaj ntxhiab tsw qab uas yog qab qab saj thiab khov. Cov kua no yog cov tshuaj lom me ntsis. Ethylene glycol yog miscible nrog dej vim tias nws muaj -h pab pawg uas muaj peev xwm tsim cov hydrogen bonds.
Dab tsi yog diethylene glycol (Deg) Cas 111-46-6?
Hauv kev sib piv, DEG, nrog cov tshuaj noj tshuaj c4h10o3, muaj cov qauv nyuaj dua. Nws muaj ob lub ethylene glycol units txuas los ntawm ib tug awher oxygen atom.
Diethylene glycolyog cov organic compound muaj tshuaj lom neeg c4h10o3. Nyob rau hauv chav tsev kub, nws yog cov kua tsis muaj kob thiab ntxhiab tsw ntxhiab. Txawm li cas los xij, nws yog hygroscopic thiab lom. Nws muaj qab zib. DEG tshuaj yog tus yam tsis pub dhau nrog dej thiab dej cawv vim tias nws muaj peev xwm tsim cov ntawv hydrogen hydrogen. Cov pob txha caj qaum ntawm cov compound no yog 106.12 g \/ mol. Lub ntsiab lus melting ntawm diethylene glycol yog -10. 45 degree thiab lub boiling point yog 245 degree.
Cov ntawv thov ntawm xws li thiab DEG
Ethylene glycolyog dav siv nyob rau hauv kev lag luam hauv tsheb ua ke ua cov tshuaj tiv thaiv tseem ceeb hauv cov tshuaj tiv thaiv thiab cov qauv txias. Los ntawm kev sib xyaw ua ke nrog dej, nws tseem txo qis taw tes thiab ua kom khov rau lub caij ntuj sov.meg kuj tseem siv tau cov kuab tshuaj thiab inks. Tsis tas li ntawd, piv txwv yog cov khoom xyaw tseem ceeb hauv kev tsim cov polyester fibers thiab polyethylene terepthalate (tsiaj) resins.
Diethylene glycol degFeem ntau yog siv los ua tus nyiam thiab lub tshuab yas ntim rau hauv kev tsim cov nplaum, xim thiab pleev xim. Raws li ib tug nyiam, nws pab khaws cov dej noo, tiv thaiv cov khoom lag luam los ntawm ziab thiab tawg. Raws li lub tshuab yas, nws txhim kho qhov yooj yim ntawm cov ntaub ntawv thiab txhim kho lawv cov txheej txheem thiab kev ua tiav. Hauv kev lag luam textile, deg ua raws li cov muag thiab roj nplua nyeem rau cov fibers. Txawm hais tias deg tuaj yeem siv los ua cov kuab tshuaj rau hauv cov txheej txheem tshuaj tshwj xeeb, nws cov kev siv cov kuab tshuaj muaj tsawg dua li qhov piv txwv.
Lub ntsiab
Ob qho ethylene glycol thiab diethylene glycol yog tsim los ntawm tib cov khoom pib; Ethylene. Qhov sib txawv ntawm piv txwv li thiab deg yog tias lub ethylene golecule yog ib tus neeg molecule yog tsim los ntawm kev sib xyaw ua ke ntawm ob lub ntsej muag glycoles glycol molecules ntawm ether daim ntawv cog lus.
