Description

CAS: 141-52-6 | C2H5NaO | 68.051 g/mol

Sodium ethoxide, 21% w/w in ethanol is used as a strong base in organic synthesis. It finds application in various chemical reactions such as condensation, esterification, alkoxylation and etherifcation. It is actively involved in Claisen condensation, Stobbe reaction and Wolf-kishner reduction. It is an important starting material for the synthesis of ethyl ester and diethyl ester of malonic acid. In Williamson ether synthesis, it reacts with ethyl bromide to form diethyl ether.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Anwendungen
Natriumethanolat, 21 % w/w in Ethanol, wird als starke Basis in der organischen Synthese verwendet. Es findet Anwendung in verschiedenen chemischen Reaktionen wie Kondensation, Veresterung, Alkoxylierung und Veretherung. Es ist aktiv an der Claisen-Kondensation, Stobbe-Reaktion und Wolf-Kishner-Reduktion beteiligt. Es ist ein wichtiges Ausgangsmaterial für die Synthese von Ethylester und Diethylester von Malonsäure. In der Williamson-Ethersynthese reagiert es mit Ethylbromid zu Diethylether.

Löslichkeit
Mischbar mit Alkohol.

Hinweise
Feuchtigkeitsempfindlich. Es hydrolysiert in Gegenwart feuchter Luft schnell zu Natriumhydroxid. Nicht kompatibel mit Wasser, starken Basen, Säuren, Oxidationsmitteln, Alkalimetallen, starken Oxidationsmitteln, Ammoniak, Säurechloriden, sauren Anhydriden, Reduktionsmitteln, Peroxiden, Säuren und chlorierten Lösungsmitteln.
