Imidazoline Specification

1.Removal in wastewater treatment of Imidazoline (CAS NO.504-75-6):
Total removal:1.87 percent
Total biodegradation:0.09 percent
Total sludge adsorption:1.76 percent
Total to air:0.03 percent
(using 10000 hr Bio P,A,S)
2. Imidazoline (CAS NO.504-75-6) is a nitrogen-containing heterocycle which is derived from imidazole.The ring contains an imine bond, and the carbons at the 4 and 5 positions are singly bonded, rather than doubly bonded for the case of imidazole.
