Explosibility of Pressurized Helium-Acetylene Mixtures.

Abstract

The helium volume concentrations in acetylene necessary to prevent explosive type reactions have been established for total pressures between 10 and 2000 psig. Reaction vessels of two sizes were used with thermal ignition by both hot wires and squibs. At 2000 psig total pressure a safe mixture of helium and acetylene requires a minimum of 90% helium by volume. At 1000 psig the helium concentration should be at least 85%, at 500 psig - 82%, and at 200 psig - 73%. (Author)
