The properties of the quinoline insoluble material in coal tar pitch and the stability of its determination method were investigated by orthogonal experiment using modified pitch as raw. The experiments were conducted according to GB/T2293-1997. The effect of three factors including the vacuum degree, the volume of toluene used and the temperature was evaluated systematically in terms of repeatability of test results. The test results were correlated to the experimental parameters, which leads to the determination of the optimum experimental conditions. The results show that the stability or repeatability of test results tends to be affected, to higher degree, by the vacuum degree and the volume of toluene used in the experiment. The optimum conditions are as follows: the vacuum degree is 0.060 MPa and the toluene volume used is 80 mL.
