ABSTRACT:
Acetonitrile is purified by treatment with ozone. After ozone treatment is ended, acetonitrile is passed through packed columns of molecular sieve, activated alumina and charcoal or graphitized carbon; the process results in virtually pure acetonitrile obtained at an efficiency unachievable by prior art processes.
