Rate constants for reactions of chlorine atoms with a series of alcohols by relative rate method

摘要：在292±1K温度和1.01×10⁵Pa压力下,以丙烷为参照物,采用相对速率方法测定了一系列醇与氯原子在气相中的反应速率常数,这些醇与氯的反应速率常数分别为(单位:10⁷m³·mol^-1·s^-1):甲醇k₁=3.29,乙醇k₂=6.14,正丙醇k₃=8.97,异丙醇k₄=4.00,正丁醇k₅=11.7,异丁醇k₆=12.5,叔丁醇k₇=2.05,正戊醇k₈=15.8,异戊醇k₉=12.3.

Abstract：The rate constants for reactions of chlorine atoms with a series of alcohols in gas-phase have been measured at 292±1K and1.01×10⁵Paby a competitive technique. The alcohols include methanol(k₁), ethanol(k₂), n propanol(k₃), iso propanol(k₄), n butanol(k₅), iso butanol(k₆), tert butanol(k₇), n pentanol(k₈) and iso pentanol(k₉). The measured rate constants are k₁=3.29, k₂ =6.14, k₃ =8.97, k₄=4.00,k₅=11 7,k₆=12.5,k₇=2.05,k₈=15.8, and k₉ =12.3, respectively (in units of 10 ⁷m³·mol^-1 ·s^-1 ).
