Uses

Different sources of media describe the Uses of 1318-93-0 differently. You can refer to the following data:
1. In industrial chromatographic technique, e.g., US 2626888 and GB 697060 (1953 to Merck & Co.), describing the elution of vitamin B12-active substances adsorbed on montmorillonite adsorbents. K-CATALYST used in the petroleum industry. Also as catalyst carrier.
2. Montmorillonite is used in industrial chromatographic techniques, widely used in petroleum industry, catalyst carrier. It acts as a solid Lewis acid catalyst.

General Description

Montmorillonite is a layered clay mineral (2:1 phyllosilicate) that belongs to a class of the smectite group. It is a naturally abundant material and is chemically modified by the cation-exchange method for the preparation of polymer nanocomposites.
