Sodium ethoxide, also referred to as sodium ethanolate, is the ionic, organic compound with the formula CH 3 CH 2 ONa, C 2 H 5 O Na, or NaOEt (Et = ethyl). It is a white solid, although impure samples appear yellow or brown. It dissolves in polar solvents such as ethanol. It is commonly used as a strong base. [2]
The term alkoxide refers to the anionic conjugate bases of alcohols (RO −) or to ionic compounds containing such an anion. Alkoxide compounds are derivatives of alcohols where the hydrogen of the –OH group is replaced by a metal ; [ 2 ] for example, the sodium salt of ethanol ( CH 3 CH 2 OH ) is sodium ethoxide , containing ethoxide anions ...
In chemistry, an alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They are written as RO −, where R is the organyl substituent. Alkoxides are strong bases [citation needed] and, when R is not bulky, good nucleophiles and good ligands.
Other strong non-nucleophilic bases are sodium hydride and potassium hydride. These compounds are dense, salt-like materials that are insoluble and operate by surface reactions. These compounds are dense, salt-like materials that are insoluble and operate by surface reactions.
This synthesis was performed without modification to the Madelung synthesis, using sodium ethoxide base at a temperature of 320 – 330 °C. This indacene has shown to be an organic light-emitting diode that may have important applications for low-cost light displays in commercial industry.
Because carbonyl compounds are only weakly acidic, a strong base is needed for enolate ion formation . If an alkoxide such as sodium ethoxide is used as base, deprotonation takes place only to the extent of about 0.1% because acetone is a weaker acid than ethanol (pK a = 16).
As being a diethyl malonate derivative, it can be combined with urea under the action of a strong base to form a barbiturate. In this case, diethyl diethylmalonate plus urea forms barbital under the action of sodium ethoxide.
