Title
Well ordered two-dimensional SnSBA-15 catalysts synthesized with high levels of tetrahedral tin for highly efficient and clean synthesis of nopol
Abstract

Highly ordered two-dimensional SnSBA-15 molecular sieve catalysts with different concentrations of tin species have been synthesized using Pluronic P123 as a structure directing agent under pH-adjusting direct hydrothermal method and have been used for synthesis of nopol by Prins condensation of β-pinene with paraformaldehyde. The influence of various reaction parameters on this reaction has been investigated. The Prins condensation reaction has also been carried out with different solvents for finding the best solvent with a good catalytic activity. In addition, the Prins condensation of β-pinene with paraformaldehyde in the presence of propyl cyanide with water has been carried out for the synthesis of nopol, and in this condition the catalytic activity of the catalyst used was not seriously affected. On the basis of all catalytic results, SnSBA-15(5) is found to be a highly active, water-resistant and recyclable heterogeneous catalyst for selective synthesis of nopol.

Graphical abstractMesoporous SnSBA-15 catalysts have been synthesized under pH-aDH method and unambiguously characterized by several instrumental techniques for the confirmation of standard mesoporous materials, and they have been successfully used for selective synthesis of nopol. SnSBA-15(5) is found to be a highly active, water-resistant and recyclable heterogeneous catalyst for the selective synthesis of nopol.Figure optionsDownload full-size imageDownload high-quality image (73 K)Download as PowerPoint slide
