“…There is a series of works where the anoxic explosive decomposition of acetylene is considered as a detonation wave of condensation in acetylene pyrolysis (Emelianov et al, 2010). The experimentally observed deviations in the Arrhenius dependences of the induction periods of detonation waves of condensation are shown to be well described by the proposed quantum corrections (Drakon et al, 2014b). The influence of CF 3 H and CCl 4 additives on the A c c e p t e d M a n u s c r i p t 3 development of acetylene detonation was experimentally investigated in a shock tube in (Drakon et al, 2014a).…”

Induction periods of self-decomposition of anoxic acetylene diluted by a propane-butane mixture or hydrogen were measured experimentally behind incident and reflected shock waves. A source of the shock wave was provided by a detonation wave that was initiated in a stoichiometric acetylene-oxygen mixture, and then changed to the shock wave in investigated mixtures of acetylene with admixtures. Produced shock waves had an intensity 3.0-9.0 MPa at duration 100-1000 μs. Dependence of the induction period of detonation of acetylene on temperature behind the incident/reflected shock wave was presented. Induction periods were obtained for the acetylene mixtures undiluted by inert gases at initial pressures 0.1 MPa and 0.25 MPa, and degrees of compression 10-20. It was shown that the induction period has a minimal value at a non-zero concentration of admixture.
