Naoh dehydration
Witryna22 cze 1995 · The results indicate that both NaOH and LiOH interact with Ca (OH) 2 during drying and calcination. The alkali hydroxides tend to dehydrate along with Ca … WitrynaSome bases that have been successfully used for enolate anion formation are: NaH (sodium hydride, pK a > 45), NaNH 2 (sodium amide, pK a = 34), and LiN [CH (CH 3) 2] 2 (lithium diisopropylamide, LDA, pK a 36). Ether solvents like tetrahydrofuran (THF) are commonly used for enolate anion formation.
