C-Alkylation has been utilized in the solubilization of various coals. Low rank, high oxygen Illinois No. 6 coal was alkylated with different alkylating agents under different conditions to determine the most suitable reaction conditions. A new method of alkylating coal with n-butyl lithium and potassium tertiary butoxide in refluxing heptane has been studied. The influence of the solvent for alkylation on the pyridine solubility of the product was studied. The pyridine solubility of the products obtained with n-butyl iodide ranged from 39% for the reaction in heptane to 5l% for the reaction in tetrahydropyran. Tetrahydrofuran, in contrast, produced only 33% pyridine soluble product. The reactivity pattern for alkylation was determined by deuterium and carbon NMR spectroscopy of the products that were obtained with deuterium and carbon-13 labelled alkylating agents.
