N2 - The crystal structure of single and mixed long chain n-paraffins from the melts and from solution in decane was investigated using X-ray diffraction. Model waxy oil samples were prepared by dissolving C28, C32, C36 or their binary mixtures in decane. One-dimensional X-ray diffraction images were collected at room temperature from samples of paraffin crystals in the reflection mode. The results showed that the paraffin crystals from rapidly cooled solutions showed less short range lateral order and correspondingly shorter layer spacings due to altered packing angles and some coiling of the chains.
