“…Sangalov, B.L. Rytov, and others [2][3][4][5] -it is proposed, for kinetically rapid chemical processes, including the process of synthesising butyl rubber, to use a tubular turbulent reactor. This is due to the fact that, on the one hand, a tubular turbulent reactor has a much smaller volume (0.04 ± 0.02 m 3 [1]) by comparison with a mixing reactor, and on the other hand, the introduced catalyst in the tubular turbulent reactor is dispersed better by the developed turbulence.…”

The macrokinetics of the synthesis of butyl rubber (cationic copolymerisation of isobutylene with isoprene over an AlC3 catalyst in a CH3Cl medium, initial synthesis temperature 173 K) in a circular-type tubular turbulent reactor was calculated. It was established that, with decrease in the size of the reaction region (cylinder diameter reduced from 0.2 to 0.1 m) and in the flow rate of the reaction suspension (reduced from 10 to 1 m/s), there is a reduction in the number-average molecular weight (from 91 700 to 1360) and in the weight-average molecular weight (from 257 000 to 134 000) of the synthesised butyl rubber and an increase in its polydispersity (from 2.8 to 110).

The paper presents the construction of a continuous multifunctional mass transfer apparatus which can perfectly adjust to meet technological requirements for a wide range of environmental, chemical, petrochemical, biological processes. The processes include absorption, adsorption, desorption, chemisorption, ion exchange, rectification, drying, extraction, gas scrubbing. The apparatus can carry out processes under the influence of intensifying electric fields of a given intensity, as well as performance of the nonisothermal mass transfer processes and the gas and liquid phase exothermic and endothermic catalytic reactions. The article also provides the most promising modifications of the developed mass transfer apparatus and the main details relating to the durability and adjustment to meet the requirements of a particular mass transfer process. The authors emphasize the prospects of using modifications of the developed mass transfer apparatus as a foamy bubbling dust collector for industrial gas scrubbing and for performance of electro-absorption, electro-adsorption, electro-desorption, ion exchange under the influence of a given electric field intensity in the environmental equipment for industrial applications and urban economy.
