Ethylene Glycol Dibutyl Ether Siv Thiab Synthesis

Kev piav qhia	Ethylene glycol dibutyl ether (EDBE) yog glycol ether nrog cov tshuaj formula (C4H9OCH2) 2. Nws yog cov kua ntshiab uas muaj ntxhiab tsw zoo ib yam li acetone thiab diethyl ether. EDBE yog soluble hauv dej tab sis insoluble hauv cov kuab tshuaj organic xws li benzene lossis toluene. EDBE tau pom tias muaj hydroxyl thiab ether pawg, uas yog qhov tseem ceeb rau nws cov tshuaj lom neeg ruaj khov. Lub intramolecular hydrogen bond ntawm pawg hydroxyl thiab ether oxygen atom kuj yog ib qho tseem ceeb hauv kev txiav txim siab tus qauv ntawm EDBE. EDBE yog tshuaj lom neeg ruaj khov nyob rau hauv chav tsev kub thiab tuaj yeem nrhiav tau los ua ib feem ntawm cov kua dej hydraulic, xim, kua roj vanish, lubricants, adhesives, tshuaj ntxuav, thiab degreasers.
Chemical Properties	Yuav luag tsis muaj xim tsis muaj kua; me ntsis tsw. Me ntsis soluble hauv dej. Hluav taws kub.
Siv	High-boiling inert hnyav; tshwj xeeb cov kuab tshuaj thiab extraction daim ntaub ntawv.
Kev piav qhia dav dav	Cov kua dej tsis muaj xim.
Cua & Dej Reactions	Oxidizes hauv huab cua los tsim cov peroxides tsis ruaj khov uas tuaj yeem tawg tshwm sim [Bretherick, 1979 p.151-154, 164].
Reactivity Profile	ETHYLENE GLYCOL DI-N-BUTYL ETHER tuaj yeem hnov mob hnyav nrog cov oxidizing muaj zog. Tej zaum yuav tsim cov nplaim hluav taws kub thiab / lossis cov pa phem nrog cov hlau alkali, nitrides, thiab lwm yam muaj zog txo cov neeg ua haujlwm. Tej zaum yuav pib lub polymerization ntawm isocyanates thiab epoxides. Sib piv inert nyob rau hauv lwm yam kev cuam tshuam, uas feem ntau cuam tshuam nrog kev rhuav tshem cov pa roj carbon-oxygen daim ntawv cog lus.
Health Hazard	Muaj tshuaj lom los ntawm kev noj tshuaj thiab kev sib cuag ntawm daim tawv nqaij. Irritates ntawm daim tawv nqaij thiab qhov muag.
Hluav Taws Xob	Kev phom sij tshwj xeeb ntawm Cov Khoom Siv Hluav Taws Xob: Ntawm qhov decomposition, ETHYLENE GLYCOL DI-N-BUTYL ETHER emits pa luam yeeb thiab khaus khaus.
Txoj Kev Purification	Co lub ether nrog aqueous 5% Na2CO3, qhuav nrog MgSO4 thiab khaws cia nrog chromatographic alumina los tiv thaiv peroxide tsim. [Beilstein 1 III 2083, 1 IV 2382.]
