Diethylene Glycol Dibutyl Ether Siv Thiab Synthesis
Chemical Properties clear colorless mus yellowish kua
Siv Butyl diglyme yog siv los rho tawm kub los ntawm hydrochloric acid daws uas muaj lwm yam hlau. Kev kho mob ntawm diglyme extract nrog hydrogen los yog oxalic acid precipitates lub ionic kub li kub hmoov.
Siv Extraction ntawm precious hlau Diethylene glycol dibutyl ether yog siv los ua ib qho hnyav hauv Grignard cov tshuaj tiv thaiv. Nws kuj tseem siv los ua cov kuab tshuaj hauv cov kub refining, hniav inks rau ceramics thiab digital inks. Nws pom daim ntawv thov hauv electrochemistry, gas absorption, extractant thiab kub boiling cov tshuaj tiv thaiv nruab nrab. Nws kuj yog siv rau hauv roj, roj nplua nyeem, textile thiab tshuaj.
Kev piav qhia dav dav Cov kua dej tsis muaj xim. ntab saum dej.
Cua & Dej Reactions Oxidizes tau yooj yim hauv huab cua los tsim cov peroxides tsis ruaj khov uas tuaj yeem tawg tshwm sim [Bretherick, 1979 p.151-154, 164]. Insoluble hauv dej.
Reactivity Profile Bis({0}}butoxyethyl) ether tuaj yeem ua rau muaj zog oxidizing cov neeg ua haujlwm. Incompatible nrog nitric acid. Tej zaum yuav tsim cov ntsev uas muaj zog acids thiab ntxiv complexes nrog Lewis acids. Hauv lwm cov tshuaj tiv thaiv, uas feem ntau cuam tshuam nrog kev rhuav tshem cov pa roj carbon-oxygen daim ntawv cog lus, kuj tsis muaj zog.
Health Hazard Tej zaum yuav muaj teeb meem los ntawm kev nqus pa, noj thiab nqus ntawm daim tawv nqaij. Ua rau qhov muag thiab tawv nqaij khaus. Cov khoom yog irritating rau mucous daim nyias nyias thiab lub Upper pa ib ntsuj av.
Hluav Taws Xob Kev phom sij tshwj xeeb ntawm Cov Khoom Siv Hluav Taws Xob: Vapor tuaj yeem taug kev deb mus rau qhov chaw taws teeb thiab rov qab.
Flammability thiab Explosibility Tsis yog nplaim taws
Kev ruaj ntseg Profile Muaj tshuaj lom los ntawm kev noj tshuaj. Mddly tshuaj lom los ntawm daim tawv nqaij. Kev sim ua kom muaj menyuam. Ib daim tawv nqaij thiab qhov muag irritant. Saib kuj GLYCOL ETHERS. Combustible thaum raug tshav kub los yog nplaim taws. Txhawm rau tua hluav taws, siv ua npuas ncauj lossis cawv ua npuas ncauj. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes.
Synthesis Rau 120 g ntawm 60% NaH thiab 500 ml ntawm toluene tau ntxiv dropweise 329 g ntawm butyl bromide thiab 486 g ntawm diethylene glycol butyl ether ntawm 50 degree. Diethylene glycol dibutyl ether tau los ntawm distillation (bp: 256 degree . nyob rau hauv ib txwm siab) los ntawm cov tshuaj tiv thaiv sib tov.
Diethylene Glycol Dibutyl Ether
Txoj kev Purification Dibutylcarbitol yog pub dawb los ntawm peroxides los ntawm kev qeeb qeeb los ntawm ib kab ntawm activated alumina. Cov eluate ces shaken nrog Na2CO3 (kom tshem tawm tej yam acidic impurities), ntxuav nrog dej, thiab muab cia nrog CaCl2 nyob rau hauv ib lub raj mis tsaus [Tuck J Chem Soc 3202 1957]. [Beilstein 1 IV 2395.]
