Chemical Properties:
  1. Potassium tert-butoxide is a strong alkaline condensing agent with its alkalinity is stronger than sodium methoxide and sodium ethoxide. At room temperature, this product is white or white-like solid powder with its chemical formula being (CH3) 3C-O-K, molecular weight being 112.21, density being 0.929, the melting point of 256-258°C and the boiling point being 275°C. It is easy to absorb moisture. It is soluble in tert-butanol with the solution being relative stable, and commonly used in the dehydrohalogenation reaction of halogenated hydrocarbon. Being exposure to air decomposition, it can be decomposed into potassium oxide and tert-butyl alcohol when coming across water. It can be manufactured through the reaction between butanol and potassium, followed by the vacuum distillation of tert-butanol in the system.
  2. Potassium tert-butoxide is used as a strong non-nucleophilic base in organic chemistry. It is widely used the condensation reaction, rearrangement and ring-opening reaction in organic synthesis. People generally apply tert-butanol solution. Potassium tert-butoxide is a kind of organic alkaline corrosion products with strong moisture absorption property and should be sealed for storage. We need to pay attention to prevention of fire and sunshine during the storage and transportation. It should be stored in a cool, ventilated and dry place.

Potassium tert-butoxide, as a strong alkaline, is widely used in the condensation, rearrangement and ring opening reaction in organic production in the fields of chemical, pharmaceutical and pesticide.
It can also be used:
To synthesize aliphatic and aromatic amides from corresponding esters and amines.
As a base in the intramolecular cyclization of aryl ethers, amines, and amides.
As a catalyst to prepare styrene derivatives from aryl halides and alkenes by Mizoroki-Heck reaction.
