| Research Abstract |
It was proved that fatty acid esters and hydroxylated alkyl aromatics are the important basic constituents of coal structure. They produced n-paraffines and alkyl aromatics. during mild hydrogenation. The n-hexane extraction residue of mild hydrogenation product was again hydrogenated and extracted by n-hexane. Its residue was repeated by hydrogenation and extraction. Those three n-hexane extracts were then fractionated to acid, base, saturate, aromatic, distillable polar neutral and undistillable polar neutral. Eich corresponding fractions were analyzed and compared. All the corresponding fractions have the similar components except the increase of heavier components in the latter hydrogenation product and the increase of shorter paraffins. The conclusion was drawn that coal composes of fatty acid and hydroxylated aromatics and its structure in homogeneous. The hypothesis that alkyl phenol was produced from the reaction between lignin and lipid was proved by the model reaction between phenol and C_<18> fatty acid. The reaction produced alkyl phenol. alkyl tetralin alkyl naphthaleng, alkyl phenanthrene etc. Lignin also produced alkyl phenols by the reaction with C_<14> alcohol.
