Small-Molecule-based Supramolecular Plastics Mediated by Liquid-Liquid Phase Separation
<p>Plastics are one of the most widely used polymeric materials. However, they are often undegradable and non-recyclable due to the very stable covalent bonds of macromolecules, causing environmental pollution and health ...
Citral-to-Menthol Transformations in a Continuous Reactor over Ni/Mesoporous Aluminosilicate Extrudates Containing a Sepiolite Clay Binder
One-pot continuous synthesis of menthols from citral was performed over 5 wt % Ni supported on a mesoporous aluminosilicate catalyst with sepiolite as a binder at 70 degrees C with a selectivity of 75% to menthols. Catalyst ...
Synthesis of Florol via Prins cyclization over heterogeneous catalysts
In this work, several heterogeneous micro- and mesoporous, acidic catalysts were tested for the selective synthesis of Florol (R), an industrial product formed via condensation and rehydration starting from isoprenol and ...
The physicochemical and catalytic properties of clay extrudates in cyclization of citronellal
<p>Four clay materials, namely, bentonite, bleaching earth, attapulgite and sepiolite, were shaped into the cylindrical body by extrusion. Clays were characterized in depth by TEM, SEM-EDX, N2 physisorption, pyridine FTIR, ...
Rapid high-throughput compatible label-free virus particle quantification method based on time-resolved luminescence
Viruses play a major role in modern society and create risks from global pandemics and bioterrorism to challenges in agriculture. Virus infectivity assays and genome copy number determination methods are often used to ...
One-Pot Transformation of Citronellal to Menthol Over H-Beta Zeolite Supported Ni Catalyst: Effect of Catalyst Support Acidity and Ni Loading
Citronellal was converted to menthol in a one-pot approach using H-Beta zeolite-based Ni catalyst in a batch reactor at 80 degrees C, under 20 bar of total pressure. The effects of H-Beta acidity (H-Beta-25 with the molar ...
One-Pot Synthesis of Menthol Starting from Citral over Ni Supported on Attapulgite-H-Beta-38 Extrudates in a Continuous Flow: Effect of Metal Location
The one-pot synthesis of menthol from citral in a continuous mode was investigated over three different types of extrudates, namely Ni supported on H-Beta-38 and extruded with attapulgite, Ni supported on attapulgite and ...
