Kev siv Ethylene Glycol

[Siv 1] Ethylene glycol feem ntau yog siv los tsim cov khoom siv hluavtaws, surfactants thiab explosives, thiab tseem siv los ua cov tshuaj tua kab mob.
[Siv 2] Ethylene glycol yog siv los ua analytical reagents, chromatographic tsom xam reagents thiab capacitor media.
[Siv 3] Ethylene glycol feem ntau yog siv los tsim polyester resins, alkyd resins, plasticizers, antifreeze agents, thiab tseem siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tawg.
[Siv 4] Ethylene glycol yog ib qho nruab nrab rau fungicides pentamethylenechlor thiab benomyl.
[Siv 5] Ethylene glycol feem ntau yog siv los npaj cov tshuaj tiv thaiv kab mob rau lub tsheb txias thiab tsim cov polyethylene terephthalate (cov khoom siv raw rau polyester fibers thiab polyester plastics). Nws tseem tuaj yeem siv los tsim nws cov khoom siv hluavtaws, cov kuab tshuaj, cov roj nplua nyeem, surfactants, softeners, humidifiers, explosives, thiab lwm yam. Ethylene glycol feem ntau siv los hloov glycerol, thiab yog siv los ua cov tshuaj hydrating thiab hnyav hauv cov tawv nqaij thiab tshuaj lag luam. , raws. Ethylene glycol muaj zog solubility, tab sis nws yog yooj yim metabolized thiab oxidized los tsim tshuaj lom oxalic acid, yog li nws tsis tuaj yeem siv dav los ua cov kuab tshuaj. Ntxiv ethylene glycol rau cov kua dej hydraulic tuaj yeem tiv thaiv cov roj-raws li hydraulic kua los ntawm corroding cov roj hmab hauv lub cev; dej-raws li hydraulic kua nrog ethylene glycol raws li lub ntsiab tivthaiv yog ib tug tsis-flammable hydraulic kua siv nyob rau hauv aircraft, tsheb thiab high-temperature molding tshuab. Ethylene glycol muaj ntau yam tseem ceeb derivatives. Tsawg molecular yuag polyethylene glycol (ethylene glycol, diethylene glycol, triethylene glycol los yog feem hu ua diethylene glycol, triethylene glycol, tetraethylene glycol) yog qhov ua tau los ntawm ethylene glycol ua los ntawm hydration ntawm ethylene oxide. Diethylene glycol tuaj yeem siv los ua cov humidifier, plasticizer, sizing tus neeg saib xyuas, luam ntawv number case hnyav, cov roj ntsha lub cev qhuav dej kom qhuav thiab muaj ntxhiab extraction hnyav. Diethylene glycol dinitrate zoo ib yam li ethylene glycol dinitrate thiab tseem yog ib qho tseem ceeb ntawm kev lag luam tawg. Qhov hnyav molecular polyethylene glycol kuj yog ib qho txiaj ntsig zoo, xws li tsis muaj xim, pob tshab, kua nplaum rau cov khoom siv waxy, nyob ntawm qhov hnyav molecular. Nws yog siv los ua lubricant, noo noo retainer, hnyav, thiab nruab nrab hauv kev lag luam roj hmab thiab zaub mov. Nws kuj yog siv rau hauv kev npaj cov tshuaj pleev ib ce thiab additives nyob rau hauv lub teb ntawm textiles thiab papermaking. Muaj ntau ntau yam ntawm ethylene glycol esters, uas yog dav siv los ua cov kuab tshuaj. Ethylene glycol esters ntawm cov saw ntev fatty acids muaj cov khoom txhim kho saum npoo thiab tuaj yeem siv ib leeg lossis ua ke nrog cov surfactants ua emulsifiers, stabilizers, dispersants, humidifiers, foaming agents thiab suspending agents. Ethylene glycol reacts nrog urea los tsim ethylene urea, uas yog siv hauv kev lag luam textile. Disodium ethylene glycol reacts nrog 1, 2-dibromoethane los ua dioxane, uas yog cov kuab tshuaj tshwj xeeb. Cov oxidants sib txawv los yog cov tshuaj tiv thaiv yog siv rau ethylene glycol. Tom qab oxidation, glycolaldehyde, glyoxal, glycolic acid, oxalic acid, thiab lwm yam tuaj yeem tau txais.
[Siv 6] Gas chromatography nyob twj ywm kua (qhov siab tshaj plaws kev khiav hauj lwm kub 50 degree, hnyav yog chloroform), kev sib cais thiab kev tsom xam ntawm qis-boiling oxygen-muaj tebchaw, amine tebchaw, nitrogen los yog oxygen heterocyclic tebchaw. Kev txiav txim siab ntawm calcium oxide hauv cov cement, cov kuab tshuaj, cov tshuaj tiv thaiv kab mob, kev tsim cov polyester resins, plasticizers, tshuaj pleev ib ce, explosives, txias-resistant lubricants, surfactants, varnishes, dyes, inks, thiab lwm yam., organic synthesis.
