Shpariy M. Improvement of ethylene chlorination technology

Dissertation research is devoted to the solving of the actual scientific and practical problem: increase of selectivity of process of liquid-phase direct chlorination of ethylene to 1,2-dichloroethane by modification of the industrial catalyst on the basis of ferric chlorides and sodium salt of perforated sulfonic acid. It is shown that the use of sodium salt of perfluorinated sulfonic acid (electron-acceptor compound) leads not only to an increase in the content of sodium ions in the catalytic system and to -achieving their design values, but also to increase the purity of 1,2-dichloroethane and reduce the content of by-products, while the dispersion of the catalytic system is of secondary importance. It is established that the modifier not only stabilizes the catalytic complex, but allows to reduce its preparation time by half. The optimal stabilizer concentration is determined.
