Second generation (2G) biofuels are produced from non-edible ligno-cellulosic biomass providing sustainable alternatives for fossil fuels. The OH reaction rate constant has been determined for the 2G biofuel ethyl levulinate (CH 3 C(O)CH 2 CH 2 C(O)OCH 2 CH 3 , ELA) (1) for the first time. The direct reaction kinetic technique of pulsed laser photolysis (PLP) coupled with resonance fluorescence (RF) detection of OH radicals has been used to determine the rate constant value of k 1 = (3.43 ± 0.36) × 10 -12 cm 3 molecule -1 s -1 (298 K), where the error given designates 2σ accuracy. Implications for atmospheric chemistry have been discussed.
