Abstract:
     The preparation method of this surface active agent is as follows: under the protection of inert gas, adding alkali metal in one time to the reaction vessel which contains organic solvent, then dropping organic solution of polycyclic aromatic hydrocarbon compound, to the previous solution under stirring, at temperature 0-50 deg.C. A stable complex solution is obtained. The available period is lengthened by adding of hydrophobic agent and some filler. the storage life is prolonged by using of suitable sealing technique.
