Mesoporous solids include metal oxides, silica, phosphates and other materials. They may contain various acidic and basic sites which are, in combination with metal nanoparticles, metal atoms, functional groups, etc., could be efficient multifunctional catalysts for cascade reactions. In this shot review, the most important aspects of such catalysts that furnish their catalytic activity and selectivity for cascade reactions in biomass processing discussed. A combination of one metal with another or with metal oxid...

EFFECT OF THE REACTOR TYPE AND SOLVENT NATURE ON THE BEHAVIOR OF POLYMER-SUPPORTED PALLADIUM CATALYSTS OF SELECTIVE HYDROGENATION OF TRIPLE BOND

(STEF92 Technology, 2025-08-15, Linda Zh. Nikoshvili, Anastasia Kunareva, Elena S. Bakhvalova, А. И. Сидоров)

This work is aimed at the search of optimal conditions of selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE). The main question was if the common slurry reactors are suitable for this reaction under ambient hydrogen pressure with the use of environmentally friendly solvents. Thus, we investigated the effect of the reactor type (shaker-type or slurry), temperature and solvent nature (isopropanol, n-butanol or toluene were used) on the behavior of a palladium catalysts (1 wt.% of P...

HYDROGENATION OF LEVULINIC ACID TO GAMMA-VALEROLACTONE USING RUTHENIUM CONTAINING CATALYSTS SUPPORTED ON AMORPHOUS AROMATIC POLYMERS

(STEF92 Technology, 2025-08-15, Linda Zh. Nikoshvili, Alexey V. Bykov, Daniil Lisichkin, Elena S. Bakhvalova, Maxim Grigoriev)

Levulinic acid (LA) obtained by processing of plant biomass is used to synthesize many important compounds, among which is gamma-valerolactone (GVL) - a platform chemical. At present, bifunctional catalysts based on inorganic supports are the most widespread in the reaction of selective hydrogenation of LA to GVL. Polymers can serve as promising alternative to inorganic supports. In the framework of the presented study, the series of amorphous aromatic polymers was synthesized using different monomers: phenanthren...
