Monoethylene Glycol (iG), diethylene glycol (Deg), thiab lawv cov neeg siv tshuaj lom neeg, cov qauv sib txawv, thiab cov ntawv thov uas ua rau lawv haum rau kev siv sib txawv. Nkag siab txog qhov sib txawv ntawm cov tebchaw ntawm cov tebchaw no yog qhov tseem ceeb rau kev lag luam xws li petrochemicals, tsheb, tshuaj, thiab lwm yam.
Dab tsi yog monoethylene glycol (meg) CAS 107-21-1
Monoethylene glycol megPuas yog qhov yooj yim glycol, nrog tshuaj rau cov tshuaj c2h6o2. Nws cov qauv muaj ob cov pa roj atoms, txhua tus sib khi rau cov pab pawg hydroxyl (-oh), ua rau nws muaj dej cawv yooj yim. Monoethylene Glycol yog ib qho tsis muaj kob, tsw ntxhiab, thiab hygroscopic ua kua nrog tus nqi qis dua. Nws yog soluble heev hauv dej, uas ua rau lub luag haujlwm rau nws lub luag haujlwm ua cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv kab mob.
Cov yam ntxwv tseem ceeb ntawm MEG:
Molecular hnyav: 62.07 g \/ mol
Bushing taw tes: 197.3 Qib (387.1 Degree F)
KO KOM QAB: {-13 degree (8.6 degree f)
Quav: 1.113 g \/ cm³
Viscosity: 16.1 CP ntawm 20 degree
Dab tsi yog diethylene glycol (Deg) Cas 111-46-6
Diethylene glycol degyog glycol tom ntej hauv cov koob thiab muaj ib qho qauv me ntsis ntau dua MEG. Nws cov mis mis yog c₄h₁₀o₃, nrog ob lub ethylene glycol units txuas los ntawm ib tug ether daim ntawv cog lus. Qhov no ua rau DEG cov kev sib txuas siab dua. Zoo li Meg, nws yog xim tsis muaj xim, tsis muaj ntxhiab, tab sis nws muaj lub zog npau npau thiab viscosity dua MEG, tso cai rau cov ntawv siv sib txawv.
Cov yam ntxwv tseem ceeb ntawm DEG:
Molecular hnyav: 106.12 g \/ mol
Boint Taw tes: 245 degree (473 Qib F)
KO KOM QAB: {{{-10. 45 degree (13.19 degree f)
Quav: 1.118 g \/ cm³
Viscosity: 35.7 CP ntawm 20 degree
Triethylene Glycol (Teg) Cas 112-27-6:
Triethylene Glycol Teg, nrog cov tshuaj siv tshuaj c6h14o4, muaj peb lub ethylene glycol molecules txuas nrog los ntawm Erersher Bonds. Teg tseem yog qhov tsis tshua muaj ntau dua li deg, nrog lub zog kub dua thiab viscosity, ua rau nws zoo tagnrho rau cov ntawv thov tshwj xeeb xws li lub cev qhuav dej.
Cov Khoom Siv Tseem Ceeb Ntawm Teg:
Molecular hnyav: 150.17 g \/ mol
Bushing taw tes: 285 degree (545 degree f)
KO khov taw tes: {-7 degree (19.4 degree f)
Quav: 1.127 g \/ cm³
Viscosity: 48 Cp ntawm 20 degree
Cov Kev Siv --- sib txawv
monoethylene glycol meg

Kev Noj Qab Haus Huv thiab Kev Txiav Txim Kev Nyab Xeeb
Monoethylene glycol thiab diethylene glycol yog kuab lom yog noj, nqus tau, lossis nqus tau ntawm daim tawv nqaij. Kev ua kom zoo thiab kev ntsuas kev nyab xeeb yog qhov tseem ceeb thaum ua haujlwm nrog cov tshuaj no. Triethylene Glycol yog suav tias tsawg dua li meg thiab deg tab sis tseem yuav tsum tau ceev faj tuav kom tsis txhob muaj kev noj qab haus huv zoo.
