Sharaxaada Alaabta
1,2-Diformyloxyethane, oo sidoo kale loo yaqaan acetoacetaldehyde ama acetate acetaldehyde, waa unug kiimiko oo leh caanaha molecular C4H6O3.Waa iskudhis acetal ah oo ka kooban laba kooxood oo formyl (aldehyde) oo ku xidhan atamka oksijiinta dhexe.1,2-Diformyloxyethane waxaa lagu soo saari karaa iyada oo la falcelinayo formaldehyde (CH2O) oo leh acetaldehyde (C2H4O) iyada oo joogitaanka kicinta acid.Waa dareere aan midab lahayn oo leh ur miro leh.1,2-Diformyloxyethane waxaa loo isticmaali karaa dhexdhexaad ah in synthesis organic iyo sida dareere ah ama reagent ee falcelinta qaarkood.Waxa kale oo loo isticmaali karaa sida wakiilka dhadhanka ee warshadaha cuntada.Si kastaba ha ahaatee, aad bay muhiim u tahay in si taxadar leh loo maareeyo xaruntan maadaama ay tahay mid gubanaysa oo laga yaabo inay ka cadhaysiiso indhaha, maqaarka iyo habka neefsashada haddii aan si habboon loo maamulin.

Isticmaalka Diformyloxyethane iyo Synthesis
| Guryaha Kiimikada | dareere biyo-cad.hydrolyzes si tartiib ah, oo xoreeya formic acid.Ku milmay biyaha, khamriga iyo etherka.guban kara |
| Adeegsada | Dheecaannada dubitaanka. |
| Sharaxaada Guud | Dareere biyo-cad.Biyo ka cufan.Barta fiishka 200°F.Waxa laga yaabaa in ay sun ku tahay liqidda.Loo isticmaalo dareerayaasha la isku qurxiyo. |
| Falcelinta Hawada & Biyaha | Biyo ku milmay. |
| Muuqaalka falcelinta | 1,2-Diformyloxyethane waxay si aan caadi ahayn ula falgashaa asiidhyada.Iyada oo leh asiidhyo oksidheer oo xooggan;kulaylka ayaa laga yaabaa inuu shido alaabta falcelinta.Sido kale si qaawan uga falceliya xalalka aasaasiga ah.Waxay dhalisaa hydrogen oo leh walxo yareynaya oo xooggan (biraha alkali, hydrides). |
| Hazard | Sun ah oo la nuugo. |
| Khatar Caafimaad | Neefsashada ama taabashada shayku waxay ka xanaajin kartaa ama gubi kartaa maqaarka iyo indhaha.Dabku waxa laga yaabaa inuu soo saaro gaasas cuncun leh, daxalaysan iyo/ama sun ah.Uumiga wuxuu keeni karaa dawakhaad ama neef-qabatin.Ka daadanaya xakamaynta dabka ama biyaha qasi waxay keeni karaan wasakh. |
| Daboolida iyo Qarxinta | Aan guban karin |
| Xogta Badbaadada | Sunta la nuugo.Indho xanuun daran.Dab qabsan kara marka kulaylka ama ololka uu la kulmo;waxay kaga falcelin kartaa walxaha oksaydhaynta.Si loola dagaallamo dabka, isticmaal CO2, kiimiko qalalan.Marka loo kululeeyo si uu u burburo waxay soo daysaa qiiq qallafsan iyo qiiq xanaaq badan. |
