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 ...
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)

Besides education, CrysTBox is mainly used in research with fields of application spanning from nuclear research [9] to archaeology and paleontology. [10] Among others, the suite was employed in development of additive manufacturing (including 3D printed biodegradable alloys, [7] metallic glass [11] or high-entropy alloys [12]), resistant coatings, [13] laser shock peening, [14] water cleaning ...
Gilbert Lab Technician Set for Girls, 1958, at the Science History Institute Johnny Horizon Environmental Test Kit, 1971, at the Science History Institute. The target market for chemistry sets was almost exclusively boys, deemed "young men of science." However, during the 1950s, Gilbert introduced a set targeting girls.
A solution of 2% sodium carbonate in water (solution B) [4] Separate storage of the aldehyde and base are necessary to prevent aldol polymerisation of the aldehyde. When exposed to an amine, reaction with acetaldehyde produces the enamine , which subsequently reacts with sodium nitroprusside to the imine .
