Thermal Degradation Products of <i>α</i>-Pinene in a Tubular Furnace in the Temperature Range from 300°C to 900°C: Contribution to Wildfire Flashovers

“…Wildfire flashovers are forms of sudden fire eruptions hosted primarily by Mediterranean climate wildlands [1] [2] and have been previously reported by firefighters who were overwhelmed by their occurrences in wildfires [3] [4]. They are also referred to by the scientific community as Accelerated Forest Fires (AFFs) [5], eruptive fires [6], or generalized blaze fires (GBFs) [4]. Flashovers in wildfires [7], occur when an accumulated mixture of plants emissions composed of biogenic volatile organic compounds (BVOCs) and their degradation products, combusts rapidly.…”

“…Therefore, for example, when pyrolyzing plants in a wildfire emit α-pinene, its higher density relative to air allows it to migrate downwind at ground level and concentrate in nearby confined topographies such as canyons [14]. If accumulated, α-pinene will degrade under the thermal stresses of the approaching fire front [5]. Normally, the thermal degradation products of BVOCs (e.g.…”
