Ethylene glycol diacetate Siv thiab Synthesis
| Chemical Properties | kua ntshiab |
| Siv | Cov kuab tshuaj rau cov roj, cellulose esters, explosives, thiab lwm yam. |
| Siv | EGDA muab cov khoom ntws zoo heev hauv cov lacquers thiab enamels thiab qhov chaw uas siv cov thermoplastic acrylic resins.Nws kuj yog ib qho hnyav hnyav rau cellulosic coatings thiab tuaj yeem siv rau hauv qee lub tshuab luam ntawv xws li tshuaj ntsuam inks.Nws tau pom tias siv los ua tshuaj tsw qab fixative, thiab tau tshaj tawm cov ntawv thov hauv cov nplaum dej. |
| Siv | Ethylene glycol diacetate tuaj yeem siv los ua acyl pub dawb rau lub cim xeeb ntawm peracetic acid, thaum lub sij hawm chemoenzymatic synthesis ntawm caprolactone.Nws tuaj yeem ua haujlwm ua tus thawj coj rau kev sib txuas ntawm cov enzymatic ntawm poly (ethylene glutarate). |
| Kev piav qhia dav dav | Cov kua tsis muaj xim nrog cov ntxhiab tsw qab ntxiag.Ceev 9.2 lb / gal.Flash point 191 ° F.Kub taw tes 369 ° F.Combustible tab sis yuav tsum tau siv zog rau ignite.Siv rau hauv kev tsim cov naj hoom, luam ntawv number case, lacquers thiab resins. |
| Cua & Dej Reactions | Dej soluble. |
| Reactivity Profile | Ethylene glycol diacetate reacts nrog aqueous acids kom tso cua sov nrog rau cawv thiab acids.Muaj zog oxidizing acids tuaj yeem ua rau cov tshuaj tiv thaiv muaj zog uas txaus exothermic rau ignite cov tshuaj tiv thaiv cov khoom.Thaum tshav kub kub kuj yog tsim los ntawm kev sib cuam tshuam nrog cov tshuaj caustic.Flammable hydrogen yog tsim nrog alkali hlau thiab hydrides. |
| Health Hazard | Inhalation tsis muaj teeb meem.Cov kua ua rau mob me me ntawm qhov muag.Kev noj haus ua rau muaj kev ntxhov siab lossis tsis nco qab. |
| Hluav Taws Xob | Ethylene glycol diacetate yog combustible. |
| Flammability thiab Explosibility | Tsis cais |
| Kev ruaj ntseg Profile | Muaj tshuaj lom los ntawm txoj kev intraperitoneal.Mob me me los ntawm kev noj thiab kev sib cuag ntawm daim tawv nqaij.Qhov muag irritant.Combustible thaum raug tshav kub los yog nplaim taws;tuaj yeem cuam tshuam nrog oxidizing cov ntaub ntawv.Txhawm rau tua hluav taws, siv cawv ua npuas ncauj, CO2, tshuaj qhuav.Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating fumes. |
| Txoj kev Purification | Qhuav lub di-ester nrog CaCl2, lim (tsis suav nrog noo noo) thiab fractionally distil nws nyob rau hauv lub siab txo.[Beilstein 2 IV 1541.] |
