Zusammenfassung:PCT No. PCT/JP96/02881 Sec. 371 Date Feb. 17, 1998 Sec. 102(e) Date Feb. 17, 1998 PCT Filed Oct. 6, 1996 PCT Pub. No. WO97/13808 PCT Pub. Date Apr. 17, 1997A liquid amine compound which can be applied to various uses such as emulsification for bitumens since it has as high surface activity as those of solid amines and is more excellent in workability as compared with the solid amines, and an emulsifier for bitumens produced by using the amine compound. Furthermore, a process for producing an emulsifier a bituminous emulsion by reacting an aliphatic amine having at least one hydrocarbon group having not less than 8 carbon atoms with a carbonyl compound and adding an acid thereto to adjust the pH of the amine compound so as to be not more than 5, and a process for producing a bituminous emulsion composition by using the amine compound.
