Evaluation of Corrosion Inhibitors as Lubricity Improvers
Abstract
The technical effort described herein was directed as evaluating the corrosion inhibitors (CI) currently approved under the MIL-I-25017D qualified products list (QPL). The thrust of the effort focused on the following: (1) establishment of relative effective concentrations for approved CI, (2) generation of working curves to profile CI performance in jet fuels, (3) development of an approach for incorporating a lubricity requirement into MIL I- 25017, (4) refinement of the reverse phase high performance liquid chromatography (RPHPLC) method for determining CI content in jet fuels, (5) determination of applicability of the RPHPLC to WPL CI, and (5) generation of an RPHPLC spectral library of WPL CI in JP-4. IPC-4410 was found to be among the most effective CI at improving the lubricity properties of jet fuels, while TOLAD 249 was shown to be the least effective. Pratt & Whitney found that a requirement for lubricity enhancement could easily be incorporated into MIL-I- 25017 with no significant effect on other criteria used in qualifying a candidate CI. The RPHPLC method for determining levels of CI in jet fuel was found to be applicable to all 15 QPL CI.
