Clinoptilolite as a natural, active zeolite catalyst for the chemical transformations of geraniol

Abstract This work presented the studies with natural zeolite—clinoptilolite as catalyst for isomerization of geraniol. During research, it turned out that studied process is much more complicated, and not only takes place in it, but also dehydration, oxidation, dimerization, cyclization fragmentation carbon chain. Geraniol an organic raw material which can be obtained by a chemical synthesis from plants (renewable biomass) distillation or extraction method, example source geraniol plant—geranium. Before catalytic tests clinoptilolite was characterized instrumental methods, such as: XRD, porosity studies—nitrogen adsorption at 77 K, SEM, EDXRF, FT-IR. Gas chromatography analyses showed main products were 6,11-dimethyl-2,6,10-dodecatrien-1-ol thumbergol. The selectivity thumbergol depended on temperature, content reaction time. These parameters changed following ranges: 80–150 °C (temperature), 5–15 wt% (catalyst content) 15–1440 min. (reaction time). most favorable conditions obtaining were: temperature 140 ºC, 12.5 time 180 At these conditions, conversion amounted to 98 mol%, selectivities 14 47 respectively.
