Sigle-pulse shock-tube study on the decomposition of 1-pentyl radicals

摘要

1-Pentyl radicals have bene eomcposed in single-pulase shock-tube experiments.the precursor is n-pentyl iodide,and the reaction conditiosn are 850-1000 K and 1.5-5 bar pressur.With 1-pentyl radicals being released with the rate expression k(n-C_5H_11I = l-C_5H_11 +I)=4 x 10~14 exp (-25,820/T)s~-1 we find the branching ratios for the decomposition to form olefin products to be k(l-C_5H_11=2C_2H_4 + CH_3)/k(l-C_5H_11)=2.3 exp (2018/T) where k(l-C_5H_11) is the total rate ocnstant fro l-pentyl radical decomposition.
