The atmospheric fate of a series of Methyl Saturated Alcohols (MSA) has been evaluated through the 11 kinetic and reaction product studies with the main atmospheric oxidants. Rate coefficients (in cm3 molecule-1 s-1 12 unit) measured at 298K and atmospheric pressure ( 740 Torr) were as follows: (3.71 ± 0.53) × 10-10, (1.91 ± -11 -15 13 0.65) × 10 and (2.92 ± 1.38) × 10 for reaction of E-4-methyl-cyclohexanol with Cl, OH and NO3, respectively. 14 (2.70 ± 0.55) × 10-10 and (5.57 ± 0.66) × 10-12 for reaction of 3,3-dimethyl-1-butanol with Cl and OH radical 15 respectively and (1.21 ± 0.37) × 10-10 and (10.51 ± 0.81) × 10-12 for reaction of 3,3-dimethyl-2-butanol with Cl 16 and OH radical respectively. The main detected products were 4-methylcyclohexanone, 3,3-dimethylbutanal and 17 3,3-dimethyl-2-butanone for the reactions of E-4-methyl-cyclohexanol, 3,3-dimethyl-1-butanol and 3,3-dimethyl- 18 2-butanol respectively with the three oxidants.
