nitrosyl chloride, NOCl, removal!
Hi.
Does anyone know if its possible to remove nitrosyl chloride, NOCl, from a stream/mixture of gases (presens of water)? NOCl can reproduce aqua regia,
witch is something that I don't want...
I have tried with a dry soda lime (NaOH/KOH/Ca(OH)2/water) scrubber with a gas-flow at 1.2 L/min, and its not giving the desireble effect.
You would think the NOCl would be hydrolized by NaOH, but it doesn't seem like it...
/cheers

Reference Information
Catalog of Infrared Spectra far Qualitative Analysis of Gases
RAYMOND H. PIERSON, AARON N. FLETCHER, and E. ST. CLAIR GANTZ1
Analytical chemistry yr:1956 vol:28 iss:8 pg:1218
Abstract
A catalog of infrared spectra of 66 gases and vapors is
presented, which should increase the usefulness of the
infrared technique for qualitative analysis of unknown
gas mixtures. -4 chart is also given as an aid to rapid
identification of the constituents of an unknown sample.
Threshold values revealed by the chart show the
sensitivity of the infrared method under specific conditions
for the various gases and vapors reported. The
methodologies illustrated should be applicable to more
extensive cataloging of gases and vapors.
Excerp
Because of their importance in combustion studies, spectra of
nitrosyl chloride and propyne were included in the catalog, although
the materials available were not as pure as desired. A
fractionation procedure improved the purity of the nitrosyl chloride
as originally received, but the contaminant (nitrogen dioxide)
could not be completely eliminated in this manner.
