New chelating agents were synthesized from long‐chain amines and ethylenediaminetetraacetic acid (EDTA) monoanhydride which was prepared by partial hydrolysis of EDTA anhydride. The equivalent reactions between the chelating agents and several metal ions gave the corresponding 1:1 metal chelates in good yield. These chelates and the sodium salts of the chelating agents were found to have good surface active properties, especially dispersing power and emul‐sifying power.
