摘要:

AbstractThe isomer distribution for the homogeneous sulphonation of toluene at 25.0° in 82.3 ± 0.3 wt‐% aqueous sulphuric acid has been determined by the inverse isotope dilution method as 65.1%para. 2.9%metaand 32.0%ortho. Combining these data with the relative reactivity of toluene to benzene (kt/kb) = 66.1)1the partial rate factors were calculated as fpMe258; fmMe5.7 and foMe6
