ASSESSMENT OF THREAT ARISING BY EXPLOITATION OF ACETYLENE

In the paper base reactivity parameters of acetylene are considered. The terms of safe usage of acetylene are interpreted and related to their molecular structure. Unusual susceptibility of acetylene to exothermic self-decomposition is analysed. Chemical composition and parameters of acetylene decomposition at various initial states are estimated in thermodynamic calculations. Combustion and explosion of acetylene/air and acetylene/oxygen mixtures are estimated in full range of acetylene concentration.
