Diethylene glycol divinyl ether Siv thiab Synthesis

Chemical Properties	Diethylene glycol divinyl ether yog monomeric hauv cov cim thiab siv los ua cov tshuaj nruab nrab lossis ua tus neeg sawv cev crosslinking. Ntxiv ntawm isocyanic acid tsim cov diisocyanates theem nrab. Divinyl ethers hydrolyze rau glycol thiab acetaldehyde. Chlorine los yog bromine ntxiv rau ob daim ntawv cog lus. Cov tshuaj tiv thaiv nrog cawv nyob rau hauv lub xub ntiag ntawm dej ua rau ib tug diacetal. Polymerization ntawm divinyl ether ntawm diethylene glycol nrog acidic catalysts tsim crosslinked gels. Unsaturated polyesters, crosslinked nrog styrene, tau ua noncorrosive rau hlau los ntawm kev siv divinyl ethers los txo hydroxyl ond acid tooj.
Chemical Properties	Diethylene glycol divinyl ether (DEGDVE) yog cov kua tsis muaj xim thiab pob tshab nrog qhov kub ntawm 198 degree nyob rau hauv huab cua siab. Nws yog miscible nrog cawv, ether, ester thiab aromatic hydrocarbon, tab sis tsuas yog me ntsis soluble hauv dej. Ob leeg DEGMVE thiab DEGDVE yog cov tshuaj nquag thiab yooj yim rau polymerized, thiab ib qho me me ntawm NaOH feem ntau ntxiv los ua cov tshuaj polymerization inhibitor.
Siv	Diethylene glycol divinyl ether yog ib qho tseem ceeb raw khoom thiab nruab nrab siv nyob rau hauv cov organic synthesis, kws, agrochemicals thiab dyestuff.
Daim ntawv thov	Diethylene glycol divinyl ether (DEGDVE) tau nyiam ntau xim vim yog homopolymerization thiab kev sib txawv ntawm cov khoom siv copolymerization, thiab nws feem ntau siv los ua tus neeg sawv cev sib txuas hauv ntau yam khoom siv. Hydrogels yog hydrophilic network polymers uas nqus dej ntau tab sis yog insoluble hauv dej. Cov khoom ntawm cov ntsiab lus dej siab thiab insolubility hauv dej ua rau cov khoom siv dav siv hauv biomedical fields xws li kev xa tshuaj, biosensors, contact lenses, catheters, thiab cov ntaub qhwv qhov txhab. Siv DEGDVE ua tus neeg sawv cev sib txuas thiab 60Co raws li -radiation lub teeb ci, hydrogels tau npaj los ntawm hluav taws xob copolymerization ntawm hydrophilic ethylene glycol monovinyl ether, hydrophobic BVE, thiab acidic acrylic acid. Cov txiaj ntsig hydrogels yog pH- thiab cov khoom siv ua haujlwm kub-rhiab heev. Siv DEGDVE ua tus neeg sawv cev sib txuas, 2-acrylamido-2-methylpropanesulfonic acid thiab sodium styrene sulfonate li monomers, tus neeg sawv cev ntsaws nrog qhov kub thiab txias tsis kam thiab ntsev kuj tau tsim los ntawm emulsion polymerization, uas muaj qhov tseem ceeb ntawm kev siv. nyob rau hauv kev daws teeb meem ntawm cov dej ntau lawm nyob rau hauv cov roj qhov dej thiab plays lub luag hauj lwm tseem ceeb nyob rau hauv kev txhim kho cov roj rov qab ratio. Cov khoom siv peb-dimensional nrog rau qhov chaw tshwj xeeb tuaj yeem ua ke los ntawm kev sib txuas sib txuas copolymerization nrog DEGDVE thiab siv los ua cov khoom siv hloov pauv. Piv txwv li, cross-linking copolymerization ntawm methyl vinyl sulfide nrog DEGDVE muab cov khoom siv polymer nrog cov qauv yas, uas tau hloov kho thiab siv los ua cov matrices ntawm cov khoom superbases rau ethyllation ntawm acetone thiab vinylation ntawm diethylene glycol lossis ethylene glycol.
Flammability thiab Explosibility	Tsis yog nplaim taws
Synthesis	Acetylene reacts nrog diethylene glycol nyob rau hauv lub xub ntiag ntawm ib tug catalyst xws li poov tshuaj hydroxide los yog potassium diethylene glycol kom yield DEGMVE thiab Diethylene glycol divinyl ether (DEGDVE):
