Methylation of humic acid derived from outcrop coal by two different methods gave products with methoxyl contents which did not agree with values expected from earlier functional group analyses. The discrepancies can be explained by postulating the presence in the humic acid of activated hydroxyl gr

The dielectric properties of both raw and beneficiated fractions of a Jharia coal sample were measured in the frequency range 100 kHZ-12 MHZ. It has been observed that as ash yield increases, dielectric constant also increases. An empirical relation A = ae3 + b has been proposed, where A is the ash
