Two Polish brown coals and two low-rank bituminous coals were subjected to low-temperature rapid pyrolysis to obtain tars. The reactive (phenolic, carbonyl and carboxyl) oxygen groups in the oils, asphaltenes and preasphaltenes of the tars were quantified. The amount of reactive oxygen groups in the
