Potassium Tert-Butoxide(KTB)
Product Parameters
Basic Properties
Appearance: Usually a white or off-white powder, sometimes pale yellow depending on purity.
Basicity: As a strong base (pKa of t-BuOH ~ 17), it is ideal for deprotonating weakly acidic C-H bonds.
Solubility: Soluble in tert-butanol itself and exhibits good solubility in common organic solvents such as tetrahydrofuran (THF), dimethyl sulfoxide (DMSO), and dimethylformamide (DMF). It reacts violently in water.
Hygroscopicity and Reactivity: KTB is extremely hygroscopic, rapidly absorbing moisture and carbon dioxide from the air, decomposing into potassium hydroxide and potassium carbonate, thus leading to its degradation. Therefore, it must be stored and handled under strict sealing conditions under an inert gas atmosphere (such as nitrogen or argon).
Steric Hinderment: Its large tert-butyl group creates a significant steric hindrance effect. This not only affects its nucleophilicity but also makes it prone to forming thermodynamically more stable alkenes in elimination reactions (following Hoffmann's rule).
Main Applications
Synthesis of key intermediates in the pharmaceutical industry
Strongly basic reagents in organic synthesis
Polymerization catalysts
Semiconductor and electronics industries
Safety Precautions
Hazards: KTB is highly corrosive and irritating to skin, eyes, and respiratory tract. It reacts violently with water, releasing heat and potentially causing combustion.
Handling: Must be performed in a well-ventilated environment (e.g., a fume hood) while wearing appropriate personal protective equipment, such as goggles, corrosion-resistant gloves, and a lab coat.
Storage: Always store in a dry, inert atmosphere (nitrogen purging), sealed away from moisture, water, and acids.
