Paraffin wax is a mixture of advanced alkanes in the solid state. The molecular formula of the main component is CnH2n+2, where n=17~35. The main groups are straight-chain alkanes, and a small number of alkanes with individual branch chains and single ring cycloalkanes with long side chains; The main straight-chain alkanes are n-doxane (C22H46) and n-doxoctane (C28H58).
Paraffin does not react with common chemicals, but it can burn. Industrial can be catalytic cracking
