Product Description

Montmorillonite K-10 is a high-purity, acid-activated bentonite clay with a large surface area, excellent adsorbent properties, and solid acid catalytic activity. Its fine, free-flowing powder ensures uniform activity, making it widely used in laboratories and industry.

Common Applications Include:

• Solid acid catalysts in organic synthesis (e.g., esterification, alkylation, condensation reactions)

• Adsorbent for purification of oils, resins, and chemicals

• Support material in catalysis and chemical reactions

• Research in materials science, chemical engineering, and industrial chemistry

Montmorillonite K-10 should be stored in a cool, dry place in tightly sealed containers to prevent moisture absorption. Protective equipment such as gloves, goggles, and a dust mask is recommended during handling.
