Description
Nitric acid can drive oxidation reactions of paraffins producing nitroparaffins and
other oxidation products. Presented here is a study on the aqueous liquid phase nitric
acid oxidation of paraffin oil supported on PTFE particles. The goals ofthis study
are:
1. To evaluate the effectiveness of nitric acid in removing paraffin oil from
PTFE particle surfaces.
2. To evaluate the effects of nitric acid driven reactions with paraffin oils
under varying reaction conditions.
3. To evaluate FTIR Diffuse Reflectance Spectroscopy, DRIFT, as a tool to
accomplish the quantitative analysis of this process. These goals have been achieved employing analysis by FTIR Diffuse Reflectance,
which provides a ready means of quantifying paraffin removal. Paraffin removal
generally increases with time, temperature and nitric acid concentration and can be
described by known kinetics including activation energy and region of unity
relationship between the log of the rate constant verses Hammett acidity function.
