PRODUCTION OF alpha-CHLORO-o-XYLENE

摘要

PROBLEM TO BE SOLVED: To provide a method for producingα-chloro-o-xylene in high selectivity by industrially advantageous method using o-xylene as a starting raw material. SOLUTION: In this method for producingα-chloro-o-xylene by reacting o-xylene with chlorine by radical reaction in a liquid phase, conversion of o- xylene is controlled to 20-70%. After the above reaction, unreacted o-xylene is recycled.
