A STUDY OF THE EXPLOSION LIMITS OF SIMPLE DIFLUORAMINO COMPOUNDS.
Abstract
The key problem in the branched-chain explosion of difluoroamino propanes (DP) is the mechanism of destruction of F-atoms in about one millionth of all molecular collisions F + DP. This may occur either subsequently to the reaction F + DP = HF + R by decomposition of the free radical R to yield inert NF2 instead of NF + F, or competitively by the reaction (a) F + DP = C3H6F(NF2) + NF2 while R in the presence of F2 at low temperature reacts to yield RF + F and at high temperature decomposes to yield NF + F. Photochemical experiments with Cl2 and F2 at sub-critical concentration have confirmed the latter theory. This establishes a common branched-chain mechanism for the various DP isomers. Comparison of the kinetic data for 1,3-DP with 1,2- and 2,2-DP shows that a primary carbon atom is much less susceptible to reaction (a) than a secondary carbon atom. (Author)
