Summary: | Azacycloalkane-2,2-diphosphonic acids having the formula OO HO PARALLEL PARALLEL OH ANGLE PP ANGLE HOOH ANGLE C ANGLE (CH2n--N-R wherein R is a member selected from the group consisting of hydrogen and alkyl having from 1 to 3 carbon atoms and n is an integer from 3 to 5; as well as their water-soluble salts. The azacycloalkane-2,2-diphosphonic acids are excellent sequestering agents especially for alkaline earth metal ions. They are stabilizers for percompounds and are useful in the delaying of the setting times for gypsum. |
