摘　　要：以褐煤为原料、亚硫酸铵为磺化试剂,制备水溶性沥青。实验探索了反应时间、反应温度、亚硫酸铵用量、甲醛用量、氨水浓度对水溶性沥青产率及其性能的影响。结果表明:3g原料沥青、1g亚硫酸铵、1mL甲醛、30mL 40%氨水,反应时间1.5h,反应温度75℃条件下制备的沥青水溶物为59%。Water-soluble pitch was made with lignite as raw and ammonium sulfite as sulfonating agent. The effects of reaction time and temperature,the amounts of ammonium sulfite, formaldehyde and the concentration of ammonia on the yield and properties of the water-solluble pitch were researched. The results show that ： under the condition of 3g raw asphalt, lg ammonium sulfate, lmL formaldehyde, 30mL 40% ammonia,reacting for 1.5h at 75℃,the water-soluble pitch can dissolved 59 % in water.
