Montmorillonite K-10 is widely used as a catalyst in organic synthesis due to its high surface area and acidic properties. It is particularly effective in facilitating reactions such as Friedel-Crafts alkylation, acylation, and esterification. In the pharmaceutical industry, it serves as a support material for drug delivery systems, enhancing the stability and controlled release of active ingredients. Additionally, it is employed in environmental applications for the adsorption of heavy metals and organic pollutants from wastewater. Its ability to act as a thickening and suspending agent makes it valuable in the formulation of paints, coatings, and cosmetics. In agriculture, it is utilized to improve soil structure and water retention, promoting plant growth.
