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

摘要

A feed stream containing halogenated organic compounds and trace quantities of organic nitrates is treated to produce a stream comprising halogenated organic compounds substantially free from organic nitrates by the utilization of a hydrogenation zone operated at selective hydrogenation conditions in order to convert the organic nitrates to one or more water-soluble nitrogen compounds while minimizing the production of hydrogen halide compounds. The resulting water-soluble nitrogen compounds are thereafter removed by extraction with an aqueous stream to produce the desired product stream.
