A series of platinum catalytic systems stabilized in aromatic polymers were obtained in this work. Commercially available styrene-divinylbenzene (MN100) and polymers synthesized by one-stage crosslinking by the Friedel-Crafts reaction from benzene, naphthalene, and an equimolar benzene-naphthalene mixture were used as polymers. The obtained systems were tested in liquid-phase hydrogenation reactions of benzene, toluene, and benzene-toluene mixture, as well as anthracene in a dodecane medium. The reaction products ...

The scale of annual reproduction of cellulose-containing biomass in nature allows us to draw an unambiguous conclusion that cellulose is the only source of raw materials for the chemical and fuel industries, representing a real alternative to fossil resources and, first of all, oil. Cellulose is the main component of plant biomass. According to some estimates, almost half of the organic carbon in the biosphere is contained in cellulose. Hydrolytic hydrogenation is a special case of carbohydrate hydrogenation. With...

This paper presents the results of a study of the hydrolysis of microcrystalline cellulose in a subcritical water medium. The influence of temperature, time, cellulose/water ratio, cellulose particle size, and other parameters on the hydrolysis process was studied. The influence on the process of pretreatment of aqueous dispersions of cellulose with ultrasound was studied. It was shown that the optimal processing time is 30 min (~ 150 kJ). Over a given period of time, destruction and partial hydrolysis of the amor...
