Cov khoom
Organic Chemicals Solvent Diethylene Glycol Khoom CAS No 111-46-6 Transparent Liquid
Product Description
DEG yog tsim los ntawm ib nrab hydrolysis ntawm ethylene oxide. Nyob ntawm cov xwm txheej, qhov sib txawv ntawm DEG thiab cov glycols muaj feem xyuam raug tsim. Cov khoom tsim tau yog ob lub ethylene glycol molecules koom nrog ether daim ntawv cog lus.
"Diethylene glycol yog muab los ua cov khoom sib koom ua ke nrog ethylene glycol (MEG) thiab triethylene glycol. Kev lag luam feem ntau ua haujlwm kom ua tiav MEG ntau lawm. Ethylene glycol yog nyob deb ntawm qhov loj tshaj plaws ntawm cov khoom glycol hauv ntau daim ntawv thov. Muaj DEG. yuav nyob ntawm qhov kev thov rau derivatives ntawm cov khoom tseem ceeb, ethylene glycol, ntau dua li ntawm DEG kev ua lag luam.

Daim ntawv thov
| Siv los ua cov roj dehydrating tus neeg saib xyuas thiab aromatics extraction hnyav, kuj siv los ua textile lubricant, softener thiab finishing agent, as well as plasticizer, humidifier, sizing agent, nitrocellulose, resin thiab grease solvent. |
Diethylene glycol yog siv rau hauv kev tsim cov saturated thiab unsaturated polyester resins, polyurethanes, thiab plasticizers.DEG yog siv los ua ib lub tsev thaiv hauv cov organic synthesis, xws li morpholine thiab 1,4-dioxane. Nws yog ib qho hnyav rau nitrocellulose, resins, dyes, roj, thiab lwm yam organic compounds. Nws yog ib qho khoom siv rau kev haus luam yeeb, cork, luam ntawv number case, thiab kua nplaum.Nws tseem yog ib qho khoom siv hauv cov dej nres, lubricants, wallpaper strippers, dag pos huab thiab taws tswm ciab, thiab cua sov / ua noj roj.In cov khoom tu tus kheej (xws li daim tawv nqaij thiab lotions, deodorants), DEG feem ntau hloov los ntawm kev xaiv diethylene glycol ethers. Ib qho kev daws teeb meem ntawm diethylene glycol tuaj yeem siv los ua cov tshuaj tiv thaiv cryoprotectant; Txawm li cas los xij, ethylene glycol yog siv ntau dua. Feem ntau ethylene glycol antifreeze muaj ob peb feem pua diethylene glycol, tam sim no raws li cov khoom lag luam ntawm ethylene glycol ntau lawm.
Qhov zoo
Cov khoom lag luam zoo, kom muaj nuj nqis txaus, kev xa khoom zoo, kev pabcuam zoo Nws muaj qhov zoo dua li cov amine zoo sib xws, ethanolamine, nyob rau hauv qhov siab dua yuav siv tau rau tib lub peev xwm corrosion. Qhov no tso cai rau cov refiners los txhuam hydrogen sulfide ntawm qis dua amine tus nqi nrog tsawg zog siv tag nrho.
