I-Sodium ethoxide (isisombululo se-Sodium ethoxide 20%)

Uhlobo lwekhemikhali

Umgubo omhlophe okanye otyheli; uthambile; uyajika ube mnyama kwaye ubole xa udibana nomoya; uyabola emanzini enze i-sodium hydroxide kunye ne-ethanol; uyanyibilika kwi-ethanol epheleleyo. Iphendula ngamandla kunye nee-asidi, amanzi. Ayihambelani nezinyibilikisi ze-chlorine, kunye nokufuma. Ifunxa ikharbon dioxide emoyeni. Ivutha kakhulu.

Izicelo

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

I-Sodium ethoxide, eyi-21% w/w kwi-ethanol isetyenziswa njengesiseko esomeleleyo kwi-organic synthesis. Isetyenziswa kwiimpendulo ezahlukeneyo zeekhemikhali ezifana ne-condensation, i-esterification, i-alkoxylation kunye ne-etherifcation. Ibandakanyeka ngokukhutheleyo kwi-Claisen condensation, i-Stobbe reaction kunye ne-Wolf-kishner reduction. Yinto ebalulekileyo yokuqala kwi-ethyl ester kunye ne-diethyl ester ye-malonic acid. Kwi-Williamson ether synthesis, isabela kunye ne-ethyl bromide ukwenza i-diethyl ether.
