Monitoring the gases released during breathing or via skin has gained significance towards diagnosing diseases. In this study, a sensor chip capable of detecting nonanal gas, which is known to be marker lung cancer, was developed. The gas detection agent used vanillin, underwent aldol condensation with in presence basic catalyst, resulting formation an unsaturated aldehyde. Porous glass as reac...

Different possible applications of ion exchange resins in the framework biorefinery catalytic are discussed this article. Three case studies were selected for approach, connected to three main routes biomass upgrading: syngas upgrading high-value chemicals, hydrolysate upgrading, and direct oily fraction. The tailored acidic properties these materials, as well their stability presence water, ha...

Abstract The Guerbet reaction is a possible way for transformation of ethanol to 1-butanol (important many kinds industries), which consists four steps: dehydrogenation, aldol condensation, dehydration, and hydrogenation. Due the elimination side-reactions, selective catalysis required favour production at temperature below 350 °C. main aim this work was via heterogeneous using active Mg–Al mix...

In the present study, a hollow MgO/SiO2 nanocatalyst with high alkaline properties was prepared. This heterogeneous catalyst prepared in several steps to create great active area and decrease density of catalyst. The framework applied for reaction cyclohexanone, malononitrile benzaldehyde synthesis 1 H-isocromene therough Michael addition aldol condensation at room temperature. this method, all...
