||Under certain conditions, potassium hydroxide is known to ignite acetylene, leading to the explosive decomposition of acetylene to soot and hydrogen. In certain chemical production processes acetylene and potassium hydroxide occur together at high pressure and temperature. Therefore, the ignition of acetylene and of mixtures of acetylene and nitrogen by potassium hydroxide in the temperature range of 100 to 200°C and at pressures of 0 to 20bar was studied in the laboratory. Potassium hydroxide was found to ignite the mixture of acetylene and nitrogen at temperatures between 150 and 200°C and an acetylene partial pressure of 7bar. Pure acetylene ignited in this temperature range at a pressure of 2bar.
