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 ...

For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. [13] Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than ...

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)
