Description

General description

Sodium ethoxide (Sodium ethylate) is a sodium alkoxide. It has been synthesized by reacting sodium with ethanol. It undergoes decomposition in the presence of water to afford ethanol and sodium hydroxide. It is widely employed as a strong base in organic synthesis studies.

Sodium ethoxide is an alkoxide salt mainly used as a strong base in organic reactions such as deprotonation, dehydration and dehalogenation.

Application

Sodium ethoxide may be used as a base for the palladium catalyzed cross-coupling of aryl halides and alkenylboranes to synthesize arylated (E)-alkenes.

Sodium ethoxide may be used for the preparation of tricarbonylchloro(glycinato)ruthenium(II) (CORM-3).

Polycaprolactone, a thermoplastic aliphatic polyester, is reportedly susceptible to both alkaline and enzymatic hydrolyzes. This screening study examined the susceptibility of Resilon, a polycaprolactone-based root filling composite, to alkaline hydrolysis. There were 15-mm diameter disks of Resilon and Obtura gutta-percha
