Application of a tertiary alcohol 2-methyl-3-butin-2-ol (methylbutynol, denoted as MBOH) as a probe molecule allows unambiguously distinguish between several sites: acidic sites are responsible for formation of 3-methyl-3-buten-1-yne (MBYNE) or 3-methyl-2-buten-1-al (Prenal) whereas basic sites generate acetone and acetylene (Fig.
The aim of present study was to characterize surface acidity and catalytic ability of various natural clay minerals and zeolites by test reaction of methylbutynol conversion.
TEST CATALYTIC REACTION OF METHYLBUTYNOL CONVERSION
Catalytic conversion of methylbutynol (MBOH) over natural clay minerals was used for determination of surface acidity/basicity.
CONVERSION OF METHYLBUTYNOL ON NATURAL ALUMOSILICATES
In this group of samples the highest conversion of methylbutynol was observed for palygorskite, and the lowest for hydromica and H-ZSM-5.
Moreover, the gas phase reaction of methylbutynol (MBOH) is also studied to provide information about acidity and basicity features .
To the best of our knowledge, none of the techniques reported in the literature makes use of the pyrrole-TPD and methylbutynol test reaction (MBOH) methods to investigate the properties of raw Saudi grey kaolin.
