Measurements of the rate at which methane is formed in the pyrolysis of 1,3-hexadiene at temperatures over the range 694–759 K and pressures between 25 and 200 Torr show that the dissociation reaction CH3CH2CHCHCHCH2→ CH3·+·CH2CHCHCHCH2(1) is a homogeneous, first-order reaction under these conditions and the rate expression is log (k1/s–1)=(15.92 ± 0.17)–(66 390 ± 840)/θ where θ= 2.303RT/cal mol–1(1
在其上形成甲烷1,3-己二烯的热分解在温度超过所述范围694-759 K和25至200托的压力显示速率的测量值,该离解反应CH 3 CH 2 CH CHCH CH 2 →CH 3 ·+·CH 2 CH CHCH CH 2(1)在这些条件下是均相的一级反应,速率表达式为log(k 1 / s –1)=(15.92±0.17)–(66 390±840) / θ,其中θ= 2.303 R T / cal mol –1(1 cal = 4.18 J)。
