Low temperature oxidation of linseed oil: a review | Fire

The thermal decomposition of raw linseed oil analysed by DSC consisted of three steps, an exothermic process related to oxidation between 150 and 250°C, the first stage of oxidative decomposition between 250 and 400°C and the main processes of decomposition above 400°C (Lazzari & Chiantore 1999).
