Potassium methanolate 32% is a strongly basic, reactive solution of potassium methoxide dissolved in anhydrous methanol. It is commonly used as a reagent and catalyst in industrial chemical synthesis, transesterification, and organic base-catalyzed reactions.

Chemical and Physical Properties

• Density: ~0.94–0.98 g/cm³ (varies with temperature)

• Boiling Point: Approx. 64–65°C (solvent-dependent)

• Solubility: Fully miscible in methanol; hydrolyzes upon contact with water

• Odor: Alcohol-like, sharp (from methanol)

• pH: Strongly basic (in anhydrous environment)

Applications

• Organic Synthesis: Used as a strong base and nucleophile in fine chemical and intermediate production

• Biodiesel Production: Catalyzes transesterification of fatty acid esters

• Chemical Industry: Used in alkylation, condensation, and esterification reactions

• Technical Applications: Employed in polymer chemistry and industrial formulations

Safety
Signal Word: Danger

First Aid Measures

• Eye Contact: Rinse immediately with plenty of water for at least 15 minutes. Seek urgent medical attention

• Skin Contact: Remove contaminated clothing. Rinse skin thoroughly with water and soap

• Inhalation: Move the person to fresh air. Administer oxygen if symptoms occur. Seek medical attention
