Kev piav qhia txog khoom

Cov tshuaj lom neeg

Hmoov dawb los yog daj; hygroscopic; tsaus ntuj thiab lwj thaum raug cua; lwj hauv dej ua sodium hydroxide thiab ethanol; yaj hauv ethanol kiag li. Ua rau muaj kev kub ntxhov nrog cov kua qaub, dej. Tsis sib haum nrog cov kuab tshuaj chlorinated, noo noo. Nqus cov pa roj carbon dioxide ntawm huab cua. Yooj yim hlawv.

Cov ntawv thov

Sodium ethoxide siv rau hauv kev tsim cov organic rau cov tshuaj tiv thaiv condensation. Nws kuj yog ib qho catalyst hauv ntau cov tshuaj tiv thaiv organic.

Sodium ethoxide, 21% w/w hauv ethanol yog siv ua lub hauv paus muaj zog hauv kev tsim cov organic. Nws pom daim ntawv thov hauv ntau yam tshuaj lom neeg xws li condensation, esterification, alkoxylation thiab etherifcation. Nws koom nrog Claisen condensation, Stobbe reaction thiab Wolf-kishner reduction. Nws yog ib qho khoom siv pib tseem ceeb rau kev tsim cov ethyl ester thiab diethyl ester ntawm malonic acid. Hauv Williamson ether synthesis, nws reacts nrog ethyl bromide los tsim diethyl ether.

Lub neej txee

Raws li peb qhov kev paub dhau los, cov khoom no tuaj yeem khaws cia tau 12 lub hlis txij li hnub xa khoom yog tias khaws cia rau hauv cov thawv kaw ruaj ruaj, tiv thaiv kom tsis txhob muaj lub teeb thiab cua sov thiab khaws cia rau qhov kub ntawm 5 - 30°C.
