| 摘要 |
Spherical agglomerates of dihalodimethylhydantoins and dimethylhydantoins are prepared by feeding a mixture of the hydantoins together to the surface of an agglomerating disc in conjunction with a spray of water, and subsequently drying the agglomerates. These agglomerates possess a hard structural integrity and exhibit a uniform and controlled dissolution when placed in an aqueous environment, thereby rendering them suitable for a variety of applications including automatic dishwashing detergents, industrial bleaches, as well as disinfectants for cooling towers, swimming pools and spa waters.
