Triethylene glycol yog dab tsi?
Triethylene glycoltseem hu ua triethylene glycol, triethylene glycol, triethylene glycol diethylene glycol. Tsis muaj xim, tsis muaj ntxhiab, hygroscopic, kua nplaum. Miscible nrog dej thiab ethanol, me ntsis soluble hauv ether.
Physical Properties of Triethylene Glycol (TEG)
Triethylene Glycol, tseem hu ua Glycerol Triol, yog cov kua tsis muaj xim thiab tsis muaj ntxhiab nrog cov tshuaj formula C3H8O3. Nws yog saturated trihydric cawv. Zoo ib yam li dej, TEG yog ib tug polar molecule, tus yam ntxwv los ntawm qhov siab ntawm qhov nro thiab ib tug loj dielectric tas li. Vim tias cov yam ntxwv no, TEG qhia ntau lub cev muaj zog nrog dej, xws li cov peev txheej kub thiab qhov ceev.
Chemical Properties of Triethylene Glycol (TEG)
Thaum nws lub cev muaj zog zoo ib yam li cov dej, nws cov cwj pwm tshuaj lom neeg txawv heev. Raws li kev haus cawv, TEG muaj peb pawg hydroxyl (-OH), uas yog lub chaw ua haujlwm tseem ceeb. Cov pab pawg hydroxyl no muaj peev xwm tsim cov ntawv cog lus hydrogen zoo ib yam li cov dej hauv dej. Raws li qhov tshwm sim, TEG yog cov kuab tshuaj zoo heev thiab pom cov ntawv thov dav hauv kev lag luam xws li tshuaj, tshuaj, thiab kev ua zaub mov.
Puas yog triethylene glycol yog siab -cov kuab tshuaj ua kuab paug?
Triethylene glycol (TEG) yog ib qho siab -boiling polar solvent. Nws cov ntsiab lus kub yog kwv yees li 285℃txog 289.4℃(ntawm 101.3 kPa), muab faib ua qhov siab - boiling compound. Tsis tas li ntawd, nws nthuav tawm polarity, ua miscible nrog cov kuab tshuaj polar xws li dej, ethanol, thiab propanol, thiab me ntsis soluble hauv diethyl ether, qhia txog nws qhov polar xwm.
Vim li cas thiaj xaiv Gneebio?
Gneebio, nrog ntau xyoo dhau los ntawm kev tshawb fawb, kev tsim khoom, thiab kev lag luam ntawm cov tshuaj organic, yog ib qho ntawm cov khoom xa tawm ntawm cov khoom siv tshuaj hauv Henan, Suav. Tau ntau xyoo, peb tau cog lus rau kev lag luam tshuaj lom neeg ntawm cov khoom nruab nrab, cov khoom siv yas, cov tshuaj kho dej thiab cov tshuaj fungicides, thiab cov tshuaj niaj hnub.
Qhov zoo
1) Cov khoom xa tuaj me me thiab sub- ntim khoom muaj.
2). Muab COA, MSDS, Daim Ntawv Pov Thawj Kev Noj Qab Haus Huv, thiab Daim Ntawv Pov Thawj Keeb Kwm.
3) Zoo ua ntej, kev pabcuam zoo tshaj plaws.
