Research on Improvement in Hydroscopicity of Ammonium Nitrate with Surfactants

Surface of ammonium nitrate was modified with surfactants.Its hydroscopicity was measured.The results showed that surfactants can effectively lower the hydroscopicity of ammonium nitrate.Hydroscopicity of modified ammonium nitrate was about 30% lower than that of common ammonium nitrate.Appropriate surfactants for ammonium nitrate modification were obtained.
