Chemical Properties of Potassium Tert-Butoxide
Potassium tert-butoxide is an organic potassium compound with the following key properties:
Formula: KOC₄H₉ (or K⁺C₄H₉O⁻)
Molecular weight: 112.21 g/mol
Appearance: It is typically a white, crystalline solid that is highly hygroscopic (absorbs moisture from the air) and reactive.
Solubility: Buy Potassium tert-butoxide is soluble in polar aprotic solvents such as dimethyl sulfoxide (DMSO) or tetrahydrofuran (THF), but is insoluble in water due to its strong basic nature.
Reactivity: It is a strong base and can deprotonate weak acids, making it a useful reagent in organic chemistry. It is also highly reactive with water and moisture, and it should be stored under dry conditions.
Preparation of Potassium Tert-Butoxide
Potassium tert-butoxide is typically prepared by reacting potassium metal with tert-butanol. The reaction produces potassium tert-butoxide along with the byproduct hydrogen gas:
2K+2(CH₃)₃COH→2(CH₃)₃COK+H22 text{K} + 2 text{(CH₃)₃COH} rightarrow 2 text{(CH₃)₃CO}K + H₂2K+2(CH₃)₃COH→2(CH₃)₃COK+H2
This reaction occurs under anhydrous (dry) conditions, as potassium tert-butoxide is highly reactive with water, forming potassium hydroxide (KOH) and tert-butanol.

6. Drug Development
Potassium tert-butoxide is sometimes used in pharmaceutical chemistry for the synthesis of complex organic molecules, especially in the development of new drug compounds or active pharmaceutical ingredients (APIs).
Safety Considerations
Potassium tert-butoxide is a highly reactive and hazardous compound, especially when exposed to moisture, air, or water. Proper precautions must be taken when handling it:
1. Handling and Storage
Moisture-sensitive: Due to its hygroscopic nature and reactivity with water, potassium tert-butoxide should be stored in tightly sealed containers under an inert atmosphere such as nitrogen or argon.
Dry Conditions: It is typically stored in dry, air-free conditions (e.g., under a nitrogen atmosphere) to prevent it from reacting with moisture or air.
Protective Equipment: When handling potassium tert-butoxide, it is important to wear gloves, safety goggles, and protective clothing. Always handle it in a well-ventilated area or fume hood to avoid inhalation of any fumes.
2. Reactivity with Water
Reaction with Water: If potassium tert-butoxide comes into contact with water, it reacts violently, releasing heat and producing potassium hydroxide (KOH) and tert-butanol. This reaction is exothermic and can cause burns, so it is critical to avoid accidental exposure to moisture.
3. Inhalation or Ingestion
Toxicity: While potassium tert-butoxide is not typically ingested or inhaled intentionally, exposure to its vapors or dust can cause irritation to the respiratory system, eyes, and skin. Always use appropriate safety equipment to avoid these hazards.
First Aid: In case of exposure, flush the affected area with copious amounts of water and seek medical attention immediately. If inhaled, move the person to fresh air and seek medical care if necessary.
Conclusion
Potassium tert-butoxide is a highly versatile and reactive compound widely used in organic chemistry, particularly in synthetic chemistry and industrial applications. Its ability to act as a strong base and nucleophile makes it invaluable in many reactions, such as eliminations, dehydrohalogenations, and the formation of carbon-carbon bonds. However, due to its strong reactivity with moisture and its potential hazards, it is essential to follow strict safety protocols when handling this compound. Proper storage, protective equipment, and careful handling are crucial to ensuring safety in both laboratory and industrial settings.
