| Abstract: | 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. |
