| Strong organic alkaline | Potassium tert-butoxide is an important kind of organic base with its alkalinity being stronger than potassium hydroxide. Because of the induction effect of three methyl groups in the (CH3) 3CO-, it has stronger alkalinity and activity than other potassium alkoxides, thus being a very excellent catalyst. In addition, as a kind of strong alkaline, potassium tert-butoxide is widely used in the organic synthesis of chemical, pharmaceutical, and pesticide such as trans-esterification, condensation, rearrangement, polymerization, loop opening and the production of heavy metal orthoester. It can be used to catalyze the Michael addition reaction, Pinacol rearrangement reaction and Ramberg-Backlund rearrangement reaction. Potassium tert-butoxide is used as a condensing agent, which can be used to catalyze Darzens condensation reaction and Stobbe condensation reaction. It is also the most effective alkaline for traditional akloxide-haloform reaction generating dihalogenated carbene. Therefore, potassium tert-butoxide has attracted more and more attention from chemical, pharmaceutical, pesticide and other industries. As potassium tert-butoxide has such a wide application, the domestic and international demand for high purity potassium tert-butoxide is very large. However, due to its production cost is higher than other alkali metal alkoxides, the production technology needs to be improved, so in-depth study of potassium tert-butoxide is particularly important. |
