Physicochemical and biological conversion in heterogeneous gas–liquid systems is used increasingly in different production processes. Dispersion in a gas–liquid system is used for creating various interphase surfaces, providing high intensity heat and mass transfer. Dispersion of gases in production equipment is accomplished by different types of dispersers (pneumatic, mechanical, etc.). In resolving...
New perinone dyes for bulk dyeing synthetic polymers were synthesized. The synthesized dyes are characterized by high thermal stability. The possibility of dyeing Macrolon 28/08 polycarbonate with some of the synthesized dyes was investigated. It was shown that the dyes were uniformly distributed in the bulk of the polymer. It was found that incorporation of a perinone dye containing a pyridine radical...
