Destructive distillation is a chemical process involving the decomposition of organic material by heating to a high temperature in the absence of air or in the presence of other reagents such as steam, or solvents such as phenols or catalysts. The process breaks up or 'cracks' large molecules into a complex mixture of hundreds of different compounds smaller, more volatile, components together with a range of more heat-stable molecules; some materials react to produce only a few products and other reactions polymerise small molecules into tars and chars.
