What is Potassium Tert-butoxide?

Potassium tert-butoxide is an important organic base, more basic than potassium hydroxide. It can be used to catalyze Michael addition reaction, Pinacol rearrangement reaction and Ramberg-Backlund rearrangement reaction; potassium tert-butoxide is used as a condensing agent and can be used to catalyze Darzens condensation reaction, Stobbe condensation reaction; it is also a traditional generation of dihalogenated carbene The most efficient base for the alkoxide-haloform reaction. Therefore, potassium tert-butoxide is more and more favored by chemical, pharmaceutical, pesticide and other industries. Potassium tert-butoxide is so widely used, so there is a large demand for high-purity potassium tert-butoxide at home and abroad. But because its production cost is higher than other alkali metal alkoxides, the production technology needs to be perfected, so the in-depth study of potassium tert-butoxide is particularly important.

Potassium Tert-butoxide Uses

  1. Potassium tert-butoxide is used in pesticides, medicine, printing and dyeing, catalysts, etc.
  2. As a strong base, potassium tert-butoxide is widely used in condensation, rearrangement and ring-opening reactions in organic synthesis such as chemical industry, medicine and pesticide.

Potassium Tert-butoxide Precautions

Potassium tert-butoxide is available in both liquid and solid types. Usually the liquid industrial product is the tert-butanol solution of potassium tert-butoxide, the color of the product is light yellow or milky white, slightly turbid, and the content of potassium tert-butoxide is 10%~12%; the solid product is generally white or off-white powder The content of potassium tert-butoxide is 95%~97%. Potassium tert-butoxide is an organic alkaline corrosive product, which is highly hygroscopic. It should be sealed and stored. Generally, it should be stored in a cool, dry and ventilated warehouse. When placed, it should be kept away from heat sources, isolate fires, and prevent sunlight exposure. Potassium tert-butoxide is highly corrosive to the skin. During loading and unloading, operators should wear protective masks to prevent corrosion and burns from potassium tert-butoxide.
