✦ Synopsis

A study was conducted to measure the hydroxyl radical rate constants using a relative rate procedure in which the photolysis of methyl nitrite was the source of OH. During the course of this study, the OH rate constant was measured for a number of chlorinated solvents for which measurements have not previously been reported or for which there are f2w reliable measurements.

Room temperature OH rate constants are presented for six chlorinated hydrocarbons (ally1 chloride, henzyl chloride, chlorobenzene, epichlorohydrin, trichloroethylene, and vinylidene chloride) and four oxygenated hydrocarbons (acrolein, methacrolein, methyl ethyl ketone. and propylerie oxide). Also included are OH rate constants for alkanes (ethane. propane, isobutane. and cyclohexane), alkenes (trans-2-butene and isoprene), and aromatic hydrocarbons (benzene, toluene, 0-, m-, and p-xylene). Rate constants for compounds not previously reported include vinylidene chloride (1.49 t 0.21 x lo-'' cm3 molecule-' s-') and benzyl chloride (2.96 ? 0.15 x lo-'' cm' molecule-' s-'). The analysis for chlorinated hydrocarbons included a correction for possible chlorine atom reactions.
