Study of surface acid-base properties of natural clays and zeolites by the conversion of 2-methylbut-3-yn-2-ol

The rise of activation temperature from 500 °C to 700 °C for montmorillonite containing sample increased the conversion of MBOH due to the formation of stronger or additional number of basic sites as a result of mineral dehydroxylation. Natural clay samples with a higher content of montmorillonite (30-80%) altered the acid-base properties of the surface and observed higher ability to convert MBOH over acid and basic pathways.
