ABSTRACT:
Amino-polyacetic acids such as ethylenediaminetetraacetic acid, diethylene triaminepentaacetic acid and nitrilotriacetic acid are reacted with alkanols and then with hydrazine to form the hydrazides which may be converted to carboxyhydrazides, i.e. carbazic acids. The products perform well as chelants and sequestering agents.
