The ozonolysis of ethene in dry synthetic air at atmospheric pressure and room temperature (298 ± 2) K was investigated in a 6065-L reaction chamber by in situ analysis of stable species by FTIR and of total peroxy radicals PO2 (PO2 = HO2 + RO2) by a chemical amplifier instrument. The yields of radical production were determined based on steady state concentrations of the peroxy radicals and the partitioning between HO2 and RO2 derived from model simulations. The radical yield is 0.38 ± 0.02 for HO2 and 0.45 ± 0.03 for PO2.

The ozonolysis of vinyl ethers (1a, b) in the presence of thioadamantan-2-one (4a) gave in each case the corresponding thio-ozonide (5a, b) in around 70percent yield, whilst ozonolysis of a mixture of vinyl ethers (1a-c) and thiobenzophenone derivatives (4b-d) gave the corresponding thione-S-oxides (8b-d) in 15-30percent yields, together with the benzophenones (6b-d).

The flash photolysis-ultraviolet absorption technique was used to measure the rate constants for the reaction CH3O2 + CH3O2 -> products (1) over the temperature range 248-417 K and the pressure range 60-700 torr of N2.Rate constants were measured by observing the second-order disappearance of CH3O2 radicals.The measured Arrhenius expression is k1 = (1.40 +/- 0.20) x 1E-13 expcm3 molecule-1 s-1, where the rate constant is defined by the expression -d/dt = 2k12.
