WebAug 13, 2024 · For example, 1-bromobutane will undergo an elimination reaction with or without a sterically hindered base (such as tert-butoxide); however, anytime I see reactions involving elimination reaction with primary substrates, such as the bromo group in 1-bromobutane, tert-butoxide is used rather than ethoxide.

http://ramsey1.chem.uic.edu/chem494/downloads/files/Latimer%202403.pdf Potassium t-butoxide is commercially available as a solution and as a solid, but it is often generated in situ for laboratory use because samples are so moisture-sensitive and older samples are often of low purity. It is prepared by the reaction of dry tert-butyl alcohol with potassium metal. The solid is obtained by evaporating these solutions followed by heating the solid. The solid can be purified by sublimation.
