Ingcaciso yeMveliso

Ubume bekhemikhali

umgubo omhlophe okanye omthubi;ihygroscopic;zenza mnyama kwaye zibole xa sisemoyeni;ibola emanzini okwenza i-sodium hydroxide kunye ne-ethanol;inyibilika kwi-ethanol epheleleyo.Isabela ngobundlobongela kunye neeasidi, amanzi.Ayihambelani ne-chlorinated solvents, ukufuma.Ifunxa ikharbon diokside emoyeni.Inokutsha kakhulu.

Usetyenziso

I-sodium ethoxide isetyenziswa kwi-organic synthesis ye-condensation reactions.Ikwayi-catalyst kwi-organic reactions ezininzi.

I-sodium ethoxide, i-21% w/w kwi-ethanol isetyenziswa njengesiseko esomeleleyo kwi-organic synthesis.Ifumana isicelo kwiindlela ezahlukeneyo zeekhemikhali ezifana ne-condensation, i-esterification, i-alkoxylation kunye ne-etherifcation.Ibandakanyeka ngokusebenzayo kwi-Claisen condensation, i-Stobbe reaction kunye nokunciphisa i-Wolf-kishner.Yinto ebalulekileyo yokuqalisa i-synthesis ye-ethyl ester kunye ne-diethyl ester ye-malonic acid.Kwi-Williamson ether synthesis, idibana ne-ethyl bromide ukwenza i-diethyl ether.

Beka ubomi kwishelufa

Ngokwamava ethu, imveliso ingagcinwa kwi-12Iinyanga ukusuka kumhla wokuhanjiswa ukuba zigcinwe kwizikhongozeli ezivaliweyo, zikhuselwe ekukhanyeni nakubushushu kwaye zigcinwe kumaqondo obushushu aphakathi kwe-5 -30°C.
