摘要
Experiment of synthesizing a disperser for coal water slurry (CWS) by using fractions of anthracene oilfrom high-temperature coal tar was performed. The orthogonal test was used to investigate the influence oftemperature, time, quantity of sulfonation agent and condensation agent and the interaction of these factors onproperties of the disperser. The result shows that the influence of temperature, time, quantity of sulfonation agentand condensation agent, and the interaction of sulfonation time and sulfonation agent has a significant influence onthe properties of disperser.The optimal condition of synthesis is that in 150g of the fractions of anthracene oil, 40mL of sulfonation agent is added and sulfonated for 3 h at 130℃, then, 10 mL of condensing agent is added andcondensated for 1. 5 h at 115℃.
