Abstract:

Infrared spectra of 18 oil samples, to which varying concentrations of sulfonate were added, were made and plotted on graphs. It was shown that there was a correlation between concentration and absorption of the sulfonate inhibitors. The method is based on the fact that sulfonates absorb at wave lengths between 9 and 10 microns when exposed to infrared radiation. This absorption was found to be directly proportional to the concentration of the sulfonates and so may be used to measure content of sulfonates in oils.
