摘要

To estimate the inhibition effect of some polyfluorocarbons containing N, O, or S atoms such as (CF3)3N, (CF3)2NCF2H, (C2F5)2O, CF3SF5, and C2F5SF5on flame propagation, the laminar burning velocity was measured for mixtures of 9.50 vol methane, 90.00 vol air, and 0.50vol inhibitor and of 1.87 voln-heptane, 97.63 vol air, and 0.50vol inhibitor. The five compounds have higher ability as fire suppressants than CF3CHFCF3and CF3H, which have already been put to practical use.
