Ethanolates

Ethanolate ion

Ethanolates (also ethoxides , outdated ethylates ) are salts of metal - cation and Ethanolat- anions . The ethanolate ion is formed formally from ethanol by deprotonation . The molecular formula of the ethanolate ion is C ₂ H ₅ O ^- . Ethanolates belong to the group of alcoholates . They react violently with water, forming an alkaline solution and ethanol:

${\displaystyle \mathrm {CH_{3}CH_{2}OK+H_{2}O\longrightarrow CH_{3}CH_{2}OH+KOH(aq)} }$

For example, potassium ethanolate can be synthesized from ethanol and potassium :

${\displaystyle \mathrm {2\ CH_{3}CH_{2}OH+2\ K\longrightarrow 2\ (CH_{3}CH_{2}O^{-})K^{+}+H_{2}} }$

Ethanolates should not be confused with methanolates. The latter are derived from methanol .
