Aminopolycarboxylates, process for producing the same and use thereof

摘要

An aminopolycarboxylate is described, which is represented by the following formula (1): <CHEM> wherein M<1>, M<2>, M<3> and M<4> independently represent each an alkali metal ion. A process for producing the aminopolycarboxylate; a biodegradable chelating agent which comprises as the active component the aminopolycarboxylate; and a sequestering agent which comprises as the active component the aminopolycarboxylate are also described.
