Triethylene glycol Siv thiab Synthesis

Chemical Properties	Triethylene glycol yog ib qho ntshiab, tsis muaj xim, khov, ruaj khov kua nrog ib qho tsw qab me ntsis. Soluble hauv dej; immiscible nrog benzene, toluene, thiab roj av. Hluav taws kub. Vim tias nws muaj ob ether thiab ob pawg hydroxyl nws cov khoom siv tshuaj lom neeg muaj feem xyuam nrog ethers thiab thawj cawv. Nws yog ib qho hnyav hnyav rau cov pos hniav, resins, nitrocellulose, chav-teeb luam ntawv inks thiab ntoo stains. Nrog rau qhov tsis tshua muaj vapor siab thiab kub kub, nws cov kev siv thiab cov khoom zoo ib yam li cov ethylene glycol thiab diethylene glycol. Vim tias nws yog tus neeg sawv cev zoo hygroscopic nws ua haujlwm ua kua desiccant tshem tawm cov dej los ntawm cov pa roj. Nws kuj yog siv nyob rau hauv cov tshuab cua txias tsim los dehumidify cua.
Siv	Triethylene glycol yog ib qho hnyav uas tau npaj los ntawm ethylene oxide thiab ethylene glycol. Triethylene glycol tuaj yeem siv: Txhawm rau npaj fatty acid gelators, uas yog siv los gellate ntau yam edible thiab zaub roj. Raws li cov kuab tshuaj los npaj superparamagnetic hlau oxide nanoparticles rau hauv situ protein purification. Raws li tus neeg sawv cev absorbent nyob rau hauv subsea natural gas dehydration txheej txheem.
Siv	Nyob rau hauv ntau yam plastics kom nce pliability; hauv huab cua tua kab mob.
Siv	Triethylene glycol yog siv los ua cov yas yas, ua cov khoom siv ntxiv rau cov kua dej hydraulic thiab cov dej nres, thiab ua cov tshuaj tua kab mob. Nws yog ib qho tseem ceeb ntawm cov pigments, luam ntawv dyes, inks thiab muab tshuaj txhuam. Nws pom daim ntawv thov ua kua desiccant thiab siv rau hauv lub cev qhuav dej ntawm cov pa roj carbon dioxide, hydrogen sulfide thiab cua txias tshuab. Nws ua lub luag haujlwm tseem ceeb hauv cov khoom siv los tiv thaiv khov thiab de-icing, tu thiab kho cov khoom tu, lubricant thiab roj.
Txhais	ChEBI: Triethylene glycol yog poly (ethylene glycol) uas yog octane -1, 8-diol uas cov pa roj carbon atoms ntawm txoj hauj lwm 3 thiab 6 tau hloov los ntawm oxygen atoms. Nws muaj lub luag haujlwm ua plasticizer. Nws yog poly (ethylene glycol), diol thiab thawj cawv.
Txoj kev tsim khoom	Triethylene glycol, zoo li diethylene glycol, yog ua lag luam raws li ib tug by-product ntawm ethylene glycol ntau lawm. Nws tsim yog nyiam los ntawm siab ethylene oxide rau dej piv.
Kev piav qhia dav dav	Triethylene Glycol (TEG) yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw me me thiab yog denser dua dej. Nws yog ib tug tswv cuab ntawm ib tug series ntawm dihydroxyalcohols. TEG cov ntawv thov tseem ceeb yog muab los ntawm nws lub peev xwm los nqus dej noo. Nws yog siv los ua tus neeg ua kom lub cev qhuav dej hauv cov raj xa hluav taws xob los tshem tawm cov dej los ntawm cov roj ua ntej rov siv dua hauv qhov system. Triethylene glycol kuj muaj cov tshuaj tua kab mob me me thiab, thaum tsis muaj zog, yog siv los ua cov tshuaj tua kab mob rau cov kab mob thiab cov kab mob.
Reactivity Profile	Triethylene glycol yog ether-alcohol derivative. Lub ether yog qhov tsis tshua muaj tshwm sim. Cov nplaim hluav taws kub hnyiab thiab / lossis cov pa phem yog tsim los ntawm kev sib xyaw ntawm cov cawv nrog alkali hlau, nitrides, thiab muaj zog txo cov neeg ua haujlwm. Lawv hnov mob nrog oxoacids thiab carboxylic acids los tsim esters ntxiv rau dej. Cov tshuaj oxidizing hloov cov cawv rau aldehydes lossis ketones. Cawv muaj ob qho tib si tsis muaj zog acid thiab tsis muaj zog hauv paus cwj pwm. Lawv tuaj yeem pib ua cov polymerization ntawm isocyanates thiab epoxides. Reacts nrog muaj zog oxidants. [Hloov tshuaj lom neeg muaj kev nyab xeeb 1980. p. 932] ib.
Health Hazard	Raws li kev siv ib txwm siv, Triethylene Glycol (TEG) tsis xav tias yuav ua rau khaus tawv nqaij, qhov muag lossis ua pa. Txawm li cas los xij, hauv cov ntawv thov uas tsim cov vapors lossis pos huab, qhov nqus tau tuaj yeem ua rau ua rau ua pa. Tsis muaj qab nthab ntawm kev raug neeg ua haujlwm raug teeb tsa los ntawm American Conference of Governmental Hygienists (ACGIH), thiab tsis muaj qhov txwv qhov chaw ua haujlwm raug tsim los rau TEG. TEG yog nkag tau yooj yim biodegradable, muaj peev xwm tsis tshua muaj bioaccumulate thiab muaj toxicity tsawg rau cov kab mob hauv dej. TEG tsis yog flammable, tshwj tsis yog tias preheated.
Flammability thiab Explosibility	Tsis cais
Kev ruaj ntseg Profile	Tshuaj lom los ntawm txoj hlab ntsha. Mob me me rau tib neeg los ntawm kev noj. Kev sim ua kom muaj menyuam. Qhov muag thiab tawv nqaij irritant. Ntau cov glycol ether tebchaw muaj kev phom sij rau tib neeg kev ua me nyuam. Combustible thaum raug tshav kub los yog nplaim taws. Nws tuaj yeem cuam tshuam nrog oxidizing cov ntaub ntawv. Explosive nyob rau hauv daim ntawv ntawm vapor thaum raug tshav kub, nplaim taws, los yog spark. Txhawm rau tua hluav taws, siv cawv ua npuas ncauj, tshuaj qhuav qhuav. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes. Saib kuj ESTERS thiab GLYCOL ETHERS.
Txoj Kev Purification	Qhuav lub glycol nrog CaSO4 rau 1 lub lis piam, tom qab ntawd nws rov ua dua thiab maj mam fractionally distilled hauv qab lub tshuab nqus tsev. Khaws rau hauv lub tshuab nqus tsev desiccator tshaj P2O5. Nws yog hygroscopic heev. [Beilstein 1 IV 2400.]
