A comparison of results from the oxidation of normal and isopropylbenzene

A comparison of results from the oxidation of normal and isopropylbenzene. Litzinger, T. A.; Brezinsky, K.; Glassman, I. (Dep. Mech. Aerosp. Eng., Princeton Univ., Princeton, NJ 08544, USA). Chem. Phys. Processes Combust., 90/1-90/4 (English) 1984. CODEN: CPPCD9. ISSN: 0277-1128. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) In the oxidn. of propylbenzene (I) [103-65-1] and isopropylbenzene (II) [98-82-8] under lean and rich conditions with approx. const. fuel concns. at 1000 K and 1060 K, both fuels disappeared in a pseudo-1st-order manner, with II reacting faster than I. Styrene [100-42-5] is a major product for both fuels; however, a-methylstyrene [98-83-9] is found in significant concns. only in the case of II. PhMe [108-88-3], PhEt [100-41-4], and benzaldehyde [100-52-7] are formed in much greater concns. from I, even though less fuel had reacted than for II. Possible mechanisms are discussed. In view of the greater complexity of the results for I, the II data are more likely to give reasonable information on the overall selectivity of radicals for the benzylic H compared with primary H.
