A Chemical Kinetic Mechanism for 2-Bromo-3,3,3-trifluoropropene (2-BTP) Flame Inhibition



Donald R. Burgess Jr., Valeri I. Babushok, Gregory T. Linteris, Jeffrey A. Manion


The present paper is concerned with the development of a detailed chemical kinetic mechanism to describe the flame inhibition chemistry of the fire suppressant 2-bromo-3,3,3-trifluoropropene (2-BTP). Currently 2-BTP is considered as a fire suppressant to replace CF3Br for use in aircraft cargo bays. Cup burner tests indicate that 2-BTP is an effective flame extinguisher at concentrations similar to those required by CF3Br. However it was unexpectedly found that when 2-BTP is added at sub-inerting concentrations in the U.S. Federal Aviation Authority Aerosol Can Test (FAA-ACT) a large overpressure is obtained, causing the agent to fail the test and indicating that 2-BTP is acting as a fuel under these conditions. The development of a fundamental model explaining the chemical basis of these results would be of value to help assess the range of conditions where such behavior might be expected, as well as provide insights that could lead to the development of more effective agents.
