Ethylene glycol diacetate Ikoreshwa na Synthesis
| Ibikoresho bya Shimi | amazi meza |
| Gukoresha | Umuti wamavuta, selile ya selile, ibisasu, nibindi. |
| Gukoresha | EGDA itanga ibintu byiza byogutemba muguteka lacquers na emamel hamwe na resimoplastique acrylic resin ikoreshwa.Nibishobora kandi gukoreshwa neza kuri selile ya selile kandi birashobora gukoreshwa muri sisitemu zimwe na zimwe nka wino ya ecran.Yabonye ikoreshwa nkibikoresho byo gutunganya parufe, kandi byatanze raporo mubisabwa mumazi. |
| Gukoresha | Diacetate ya Ethylene glycol irashobora gukoreshwa nkumuterankunga wa acyl kugirango habeho kubyara aside ya peracetike, mugihe cya synthesis ya chemoenzymatique ya caprolactone.Irashobora gukoreshwa nkibibanziriza synthesis enzymatique ya poly (Ethylene glutarate). |
| Ibisobanuro rusange | Amazi adafite ibara hamwe numunuko woroshye.Ubucucike 9.2 lb / ikigali.Ingingo ya 191 ° F.Ingingo yo guteka 369 ° F.Birashya ariko bisaba imbaraga zo gutwika.Ikoreshwa mugukora parufe, gucapa wino, lacques na resin. |
| Umwuka & Amazi | Amazi ashonga. |
| Umwirondoro wa reaction | Diacetate ya Ethylene glycol ikora hamwe na acide yo mumazi kugirango igabanye ubushyuhe hamwe na alcool na aside.Acide ikomeye ya acide irashobora gutera imbaraga zikomeye zidasanzwe kuburyo bwo gutwika ibicuruzwa.Ubushyuhe nabwo butangwa no gukorana nibisubizo bya caustic.Hydrogen yaka umuriro ikorwa hamwe na metero ya alkali na hydride. |
| Ubuzima | Guhumeka ntabwo ari bibi.Amazi atera uburakari bworoheje bwamaso.Ingestion itera guhagarika umutima cyangwa koma. |
| Fire Hazard | Ethylene glycol diacetate irashobora gukongoka. |
| Gutwikwa no guturika | Ntibisanzwe |
| Umwirondoro wumutekano | Muburyo bwuburozi muburyo bwa intraperitoneal.Uburozi bworoheje nukurya no guhuza uruhu.Ijisho rirakara.Yaka iyo ihuye n'ubushyuhe cyangwa umuriro;Irashobora gukora hamwe nibikoresho bya okiside.Kurwanya umuriro, koresha inzoga ya alcool, CO2, imiti yumye.Iyo ishyutswe kugirango ibore isohora umwotsi wa acrid hamwe numwotsi ukaze. |
| Uburyo bwo kweza | Kuma di-ester hamwe na CaCl2, kuyungurura (ukuyemo ubushuhe) hanyuma ukayitandukanya uduce munsi yumuvuduko ukabije.[Beilstein 2 IV 1541.] |
