Abstract: | 18C6 Crown Complex of Amidosulfuric Acid The title compound ( 3 ) has been obtained from reaction of the crown ether 18C6 ( 1 ) with amidosulfuric acid ( 2 ) in water, methanol, and ethanol. The structure of the substance was elucidated with X-ray diffraction and IR data. The two constituents of 3 are connected through three oxygen-hydrogen bridges. 3 is ideally suited for the isolation and recovery of 1 from aqueous solutions. |
