Sodium ethoxide (Sodium ethoxide 20% xal)
| Dabeecadda kiimikada | Budada cad ama jaalaha ah;hygroscopic;madoobaado oo qudhuntaa marka ay hawada soo gasho;ku darma biyaha samaynta sodium hydroxide iyo ethanol;Wuxuu ku milmaa ethanol dhammaystiran. Wuxuu si ba'an uga falceliyaa asiidh, biyo.Aan ku habboonayn dareerayaasha koloriinaysan, qoyaanka.Kaarboon ogsaydhsaydh ka soo nuugo hawada.Aad u guban kara | |
| Codsiyada | Sodium ethoxide waxaa loo isticmaalaa isku-dhafka dabiiciga ah ee falcelinta uumiga.Waxa kale oo ay horseed u tahay falcelinno dabiici ah oo badan. Sodium ethoxide, 21% w / w ee ethanol waxaa loo isticmaalaa saldhig adag oo ku saabsan isku dhafka dabiiciga ah.Waxay ka heli codsiga fal-celin kiimikaad oo kala duwan sida uumi, esterification, alkoksylation iyo etherifcation.Waxay si firfircoon ugu lug leedahay uumi Claisen, falcelinta Stobbe iyo yaraynta Wolf-kishner.Waa qalab bilow ah oo muhiim u ah isku dhafka ethyl ester iyo diethyl ester ee malonic acid.Isku dhafka ether Williamson, waxay la falgashaa ethyl bromide si ay u sameyso diethyl ether. | |
| Nolosha shelf | Marka loo eego waayo-aragnimadayada, badeecada waxaa lagu kaydin karaa 12bilo laga bilaabo taariikhda dhalmada haddii lagu hayo weel si adag loo xidhay, laga ilaaliyo iftiinka iyo kulaylka laguna kaydiyo heerkul u dhexeeya 5 -30°C. | |
