PROCESS FOR PRODUCTION OF OXIMES COCATALYZED BY AMMONIUM SALTS OR SUBSTITUTED AMMONIUM SALTS

摘要

Oximes are produced in high yields and with high selectivity by reacting aldehydes or ketones with hydrogen peroxide and ammonia in the presence of a heterogeneous catalyst and an ammonium salt or substituted ammonium salt. The heterogeneous catalyst is synthesized on the basis of titanium, silicon and oxygen. Optionally, a Lewis-acid and/or Brønsted-acid cocatalyst can be present.
