Abstract: A silica-rich support and a catalyst containing the silica-rich support and a catalytic component. The support has a specific structure characterized by a set of claimed physicochemical properties: in the 29Si MAS NMR spectrum the state of silicon is characterized by the presence of lines with chemical shifts ?100±3 ppm (line Q3) and ?110±3 ppm (line Q4), with the ratio of the integral intensities of the lines Q3/Q4 of from 0.7 to 1.2 (FIG. 1); in the IR spectrum there is an absorption band of hydroxyl groups with the wave number 3620–3650 cm?1 and half-width 65–75 cm?1 (FIG. 2); the carrier has a specific surface area, as measured by the BET techniques from the thermal desorption of argon, SAR=0.5–30 m2/g and the surface, as measured by alkali titration techniques, SNa=10–250 m2/g, with SNa/SAr=5–30.

Abstract: A rotary dispergator comprises a rotor (4) set on a shaft (5) of a stator (2) having a coaxial row of teeth (7) and an outer concentric row of straightening blades (8), encompassing the rotor (4) from the outside, the width of radial cuts between the straightening blades (8) of the stator (2) being several times smaller than their length. The rotor (4) has an impeller comprised of straight or curved blades (10), as well as a coaxial row of blades (11). A method of producing food products consists in that with the help of the dispergator a mechano-acoustic effect with an intensity of 100-500 W/kg of product is produced on the material to be comminuted placed into a container. With the use of rotary dispergator, various food products based on a vegetable material are produced: a soybean paste, a mayonnaise.

Abstract: A silica-rich support is developed, which is used for preparing catalysts and may be employed in other fields of engineering: for producing fiber optic materials, in the manufacture of filters, etc.

Abstract: A method has been developed for preparing nicotinic acid with a yield of 82-86% mol, in which method there is no formation of harmful gas wastes and liquid wastes.The process is carried out by gas-phase single-step oxidation of .beta.-picoline with oxygen in the presence of water vapor and a catalyst on the base of oxides of vanadium and titanium, with or without additives, at a temperature of 250.degree.-290.degree. C. and mole ratios O.sub.2 :.beta.-picoline=15-40 and H.sub.2 O:.beta.-picoline=10-70.
