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.
Some new chelating agents were synthesized from ethylenediamine‐tetraacetic acid dianhydride and long chain alcohols. The equivalent reactions between the chelating agents and several metal ions gave the corresponding chelates in good yields. Surface‐and interfacial tensions, dispersing power and emulsifying power of these chelates were determined. These chelates showed excellent surface activities, especially the dispersing and emulsifying powers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
