Abstract
CW CO2 laser (the P(34) line, 6.5 W output) induced and SF6 (2.4 kPa)-sensitized decomposition of n-heptane (7.2 kPa) gives mainly ethylene. Propene, butene, ethane and methane are produced as well together with minor amounts of vinylacetylene, 1,3-butadiene, allene, n-butane, 1,4-pentadiene, pentene, and cyclopentadiene. The product distribution corresponds to that obtained in conventional thermolysis of n-heptane performed at temperatures higher than 1 000 °C. The inferences on the size and shape of the hot reaction zone are drawn on the basis of the measurement of temperature profiles in reaction cell.
