Process for the selective removal of organic nitrates from a halogenated organic stream containing trace quantities of organic nitrates

摘要

A process for treating a stream containing halogenated organic compounds and having trace quantities of organic nitrates to produce a stream comprising halogenated organic compounds free from organic nitrates by the utilization of a hydrogenation zone operated at selective hydrogenation conditions in order to convert the organic nitrates to water-soluble nitrogen compounds while minimizing the production of hydrogen halide compounds. The resulting water-soluble nitrogen compounds are removed by extraction with an aqueous stream.
