It was shown that, after the addition of NHPI to the autoxidation of isopropylbenzene
(cumene), the [O.sub.2] consumption is increased because PINO radicals react with RH faster than RO[O.sup.*].
crassifolia were investigated by monitoring of oxygen uptake rate in a universal gasometric system with 2,2'-azobisisobutyronitrile (AIBN)-initiated oxidation of isopropylbenzene
. Most pronounced effect was observed for crude ethanol (70%) extract of green leaves (Shilova et al., 2006).
([dagger]) Anthracene, chlorpyrifos, diazinon, isopropylbenzene
, 2,6-dimethylnaphthalene, 1,4-dichlorobenzene, bromacil, 3-t-butyl-4-hydroxyanisole, isopropylbenzene
, 4-cumylphenol, and 4-n-octylphenol were not detected in samples.
In the present study, data on density, viscosity, refractive index and speed of sound of binary mixture dimethylsulfoxide (DMSO) + isopropylbenzene
at 298.15, 303.15, 308.15, and 313.15K have been measured experimentally.
The addition reaction between C = C and the isopropylbenzene
oxygen radical is considered to represent the curing reaction of methyl vinyl SR (26), (29).
