摘　　要：The effects of temperature,stabilizer,the percentage of heptane in toluene heptane asphaltene solution on stabilization of petroleum asphaltene in the solution were examined with spectrophotometric method.The results showed that the stability of petroleum asphaltene in the solution increases with the increase of temperature and headgroup polarity of stabilizer.Petroleum asphaltene starts to precipiate evidently in toluene heptane asphaltene solution when the composition of heptane in the solution reaches 30%～40%(v).The effects of temperature,stabilizer,the percentage of heptane in toluene heptane asphaltene solution on stabilization of petroleum asphaltene in the solution were examined with spectrophotometric method.The results showed that the stability of petroleum asphaltene in the solution increases with the increase of temperature and headgroup polarity of stabilizer.Petroleum asphaltene starts to precipiate evidently in toluene heptane asphaltene solution when the composition of heptane in the solution reaches 30%～40%(v).
