It is believed that the oxygen-containing functionality play very important roles to control of the physical and chemical properties of coal. Especially, carboxyl group and phenolic hydroxyl group seem to be a key functionality, because of their hydrogen bonding capability and chemical reactivity. In this study, a new chemical determination method, non-aqueous titration, to determine the acidic functionality such as carboxylic acid and phenolic hydroxyl functionality has been investigated, aming to veryfy the accuracy of the experimental data obtained by the boro-hydride chemical determination method developed by us, recently.
