Beschreibung

Allgemeine Beschreibung

Potassium hydroxide is a strong alkali that can be used in nucleophilic substitution reactions, addition reactions, and basic hydrolysis reactions. It can also be used to catalyze aldol-type reactions.

Anwendung

Potassium hydroxide can be used as a base:

• In the Pd-catalyzed Heck reaction of aryl halides with alkenes.
• To synthesize β-alkylated alcohols via pincer-Ni catalyzed Guerbet reaction.
• For the hydroxylation of aryl or heteroarylboronic acids to corresponding phenols.

It can also be used as a catalyst for the:

• Transesterification of triglycerides to prepare biodiesels.
• Synthesis of β-phenylethylamines via intermolecular addition of arylamines to styrenes.
• Claisen-Schmidt condensation reaction to synthesize chalcones.

Verpackung

Dieses Produkt ist auch in Glasflaschen erhältlich.
