THE STRUCTURE OF LINEAR POLYMERS LOWER N-HYDROCARBONS
Abstract
Final refinements of the crystal structures of n octane, n hexane, and n pentane were carried out. In the case of n pentane the space group proved to be Pbcn. Further refinements of the (yz)-projection of the n heptane structure were performed, including several cycles of least squares. This structure was also basically solved in the (xz)-projection and so the mode of packing was elucidated. In addition, a redetermination of the unit cell dimensions was performed, based on Debye-Scherrer diagrams. Finally it was shown that the space group is Pl, and refinements on this basis were undertaken. The crystal system and the unit cell dimensions were determined for n nonane, n decane, n undecane, n dodecane, n tridecane, n tetradecane, and n hexadecane. The crystal data for these compounds are listed. From the study of mixtures of n C8H18 and n CloH22, and of n C8H18 and n C9H2o, it is concluded that additions of other n paraffins have no influence on the crystal structure of the main component and that no solid solutions are formed.
