摘要
A new method was developed for solubilizing a brown coal in a conventionally used solvent at room temperature. The coal pretreated with hydrogen peroxide in liquid phase at 60 degrees C for 2 h was extracted by solvent mixtures of methanol and a nonpolar solvent by the conventional method. In the solvent consisting of methanol and 1-methyl-naphthalene (0.54:0.46 volumetric ratio), surprisingly, 84 wt% of the pretreated coal were extracted.
