Sodium ethoxide is commonly used as a base in the Claisen condensation [7] and malonic ester synthesis. [8] Sodium ethoxide may either deprotonate the α-position of an ester molecule, forming an enolate, or the ester molecule may undergo a nucleophilic substitution called transesterification. If the starting material is an ethyl ester, trans ...

Sodium methoxide is prepared by treating methanol with sodium: 2 Na + 2 CH 3 OH → 2 CH 3 ONa + H 2. The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol.
It may also be prepared from the reaction of sodium ethoxide, formed in-situ from sodium and absolute ethanol, and chloroform: [2] CHCl 3 + 3 Na + 3 EtOH → HC(OEt) 3 + 3 ⁄ 2 H 2 + 3 NaCl. Triethyl orthoformate is used in the Bodroux-Chichibabin aldehyde synthesis, for example: [3] RMgBr + HC(OC 2 H 5) 3 → RC(H)(OC 2 H 5) 2 + MgBr(OC 2 H 5)
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
