I-sodium ethoxide (isixazululo se-Sodium ethoxide 20%)

Imvelo yamakhemikhali

Impushana emhlophe noma ephuzi;i-hygroscopic;iba mnyama futhi yabole lapho uchayeka emoyeni;ibola emanzini yakha i-sodium hydroxide ne-ethanol;incibilika ku-ethanol ephelele.Isabela ngobudlova kanye nama-asidi, amanzi.Akuhambisani nama-solvents ane-chlorine, umswakama.Imunca i-carbon dioxide emoyeni.Ivutha kakhulu.

Izinhlelo zokusebenza

I-sodium ethoxide isetshenziswa ku-organic synthesis yokusabela kwe-condensation.Kuphinde kube yi-catalyst ekuphenduleni okuningi kwe-organic.

I-sodium ethoxide, i-21% w/w ku-ethanol isetshenziswa njengesisekelo esiqinile ekuhlanganiseni kwezinto eziphilayo.Ithola ukusetshenziswa ekuphenduleni kwamakhemikhali okuhlukahlukene njenge-condensation, i-esterification, i-alkoxylation ne-etherifcation.Ibandakanyeka kakhulu ku-Claisen condensation, ukusabela kwe-Stobbe kanye nokunciphisa i-Wolf-kishner.Kuyimpahla ebalulekile yokuqala yokuhlanganiswa kwe-ethyl ester ne-diethyl ester ye-malonic acid.Ku-Williamson ether synthesis, ihlangana ne-ethyl bromide ukwenza i-diethyl ether.

Impilo yeshelufu

Ngokusho kokuhlangenwe nakho kwethu, umkhiqizo ungagcinwa izikhathi ezingu-12izinyanga kusukela ngosuku lokulethwa uma zigcinwe ezitsheni ezivalwe ngokuqinile, zivikelekile ekukhanyeni nasekushiseni futhi zigcinwe emazingeni okushisa aphakathi kuka-5 -30°C.
