Isoprene rubber chlorination in a gas-liquid system with turbulent mixing

Synthetic isoprene rubber (SIR) is chlorinated in a gas-liquid SIR-Cl-2-CCl 4-Ar mixture in a flow reactor operating in a cyclic mode. To attain homoge neous chlorination (the time of continuous contact between macromolecules a nd the chlorine-containing gaseous phase is much shorter than the reaction time), a special device turbulizing the gas-liquid flow was used in combina tion with chlorine dilution with an inert gas.
