WebSodium ethoxide, 21% in ethanol Revision Date 08-Aug-2024 4. First-aid measures General Advice Immediate medical attention is required. Show this safety data sheet to the doctor in attendance. Eye Contact Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Immediate medical attention is required. Alkali metal alkoxides are often oligomeric or polymeric compounds, especially when the R group is small (Me, Et). The alkoxide anion is a good bridging ligand, thus many alkoxides feature M2O or M3O linkages. In solution, the alkali metal derivatives exhibit strong ion-pairing, as expected for the alkali metal derivative of a strongly basic anion.

Sodium ethoxide, also referred to as sodium ethylate, is the ionic, organic compound with the formula C2H5ONa, or NaOEt (Et = ethane). 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. WebAug 3, 2015 · Ethoxide is a better nucleophile in acetone. Explanation: The solvent affects the nucleophilicity of ethoxide ion. A polar protic solvent like methanol can participate in hydrogen bonding with a nucleophile like ethoxide ion, creating a “shell” of solvent molecules around the ion.
