p style="margin: 0cm 0cm 0pt;">The rate constants for the reaction between chlorine atomsand either 5-methyl-2- hexanol, 2,2-dimethyl-3-hexanol, or2,4,4-trimethyl-1-pentanol at 298 K were determined using the relative methodwith 2-butanol and 1-pentanol as reference compounds. The values obtained for5-methyl-2-hexanol, 2,2-dimethyl-3-hexanol, and 2,4,4-trimethyl-1-pentanol (k ×1010 cm3 molec−1 s−1) were, respectively, (2.64 ±0.5), (2.72 ± 0.5), and (2.50± 0.4), in agreement with the values of the rate constants reported inbibliography for similar alcohols and the values estimated by structureactivityrelationship methods. The photooxidation products of 2,4,4-trimethyl-1-pentanol initiated by chlorine atoms were identified (formaldehyde,2-propanone,2,2-dimethyl propanal, 4,4,-dimethyl-2-pentanone, and3,3-dimethylbutanal), and thereaction mechanism was determined.
