Ethylene glycol diacetate Amfani da Synthesis
| Abubuwan Sinadarai | ruwa mai tsabta |
| Amfani | Mai narkewa don mai, esters cellulose, fashewar abubuwa, da sauransu. |
| Amfani | EGDA tana ba da kyawawan kaddarorin kwarara a cikin yin burodin lacquers da enamels kuma inda ake amfani da resins na acrylic thermoplastic.Har ila yau, yana da kyaun ƙarfi don suturar cellulosic kuma ana iya amfani dashi a wasu tsarin tawada kamar tawada na allo.Ya samo amfani azaman gyaran turare, kuma ya ba da rahoton aikace-aikacen adhesives na ruwa. |
| Amfani | Ana iya amfani da Ethylene glycol diacetate azaman mai ba da gudummawar acyl don samar da peracetic acid a cikin wurin, yayin haɗin chemoenzymatic na caprolactone.Ana iya amfani da shi azaman precursor don haɗin enzymatic na poly (ethylene glutarate). |
| Babban Bayani | Ruwa mara launi tare da wari mai laushi.Maɗaukaki 9.2 lb/gal.Wutar lantarki 191°F.Wurin tafasa 369°F.Mai ƙonewa amma yana buƙatar ɗan ƙoƙari don kunna wuta.Ana amfani da shi wajen kera turare, tawada bugu, lacquers da resins. |
| Ra'ayin Iska & Ruwa | Ruwa mai narkewa. |
| Bayanin Reactivity | Ethylene glycol diacetate yana amsawa tare da acid mai ruwa don yantar da zafi tare da alcohols da acid.Ƙarfin acid mai oxidizing na iya haifar da wani ƙarfi mai ƙarfi wanda ya isasshe exothermic don kunna samfuran amsawa.Ana kuma haifar da zafi ta hanyar hulɗa tare da mafita na caustic.Ana samar da hydrogen mai flammable tare da ƙarfe alkali da hydrides. |
| Hatsarin Lafiya | Shakawar ba ta da haɗari.Liquid yana haifar da ƙananan hangula na idanu.Ciki yana haifar da tawaya ko suma. |
| Wuta Hazard | Ethylene glycol diacetate yana ƙonewa. |
