“…For 1 mol of pentene cracked, approximately 2 mol of product were formed. This is in excellent agreement with the values reported by Gorin, et al (1946), and Hepp and Frey (1949). The variation of some of the products with residence time at 700°is shown in Figure 4 and the typical distribution is listed in Table I.…”

“…They concluded that Rice's theory (1935) would have to be modified to account for all the primary reactions observed. Hepp and Frey (1949) pyrolyzed 2pentene between 778 and 850°in a quartz reactor and found the first-order decomposition rate constant at 780°to be 13 sec-1. They also found the main products to be methane, butadiene, butene, propylene, and ethylene.…”

The thermal reaction of 8-pentene (cis or trans) has been performed in a static system over the temperature range of 470°-535"C a t low extent of reaction and for initial pressures of 20-100 torr. The main products of decomposition are methane and 1,3-butadiene. Other minor primary products have been monitored: trans-2-pentene, trans-and cis-2-butenes, ethane, 1,3-pentadienes, 3-methyl-l-butene, propylene, 1-butene, hydrogen, ethylene, and I-pentene. The initial orders of formation, 0.8-1.1 for most of the products and 1.5-1.8 for 1-pentene, increase with temperature. The formation of the products and the influence of temperature on their orders can be essentially explained by a free radical chain mechanism. But cis-trans or trans-cis isomerization and hydrogen elimination from cis-2-pentene certainly involve both molecular and free radical processes. The formation of 1-pentene mainly occurs from the abstraction of the hydrogen atom of 2-pentene by resonance stabilized free radicals (C5Hg.).
