Hard surface cleaners, potential

Imidazolidinones. Several mono and dichloro isomers have been prepared and tested as disinfectants (157) 1-ch1oro-4,4,5,5-tetramethylimidazo1idin-2-one [58816-19-6] l,3-dichloro-4,4,5,5-tetramethylimidaZohdin-2-one [58816-20-9] (5), mp 102—104°C l-chloro-2,2,5,5-tetramethylimidazohdin-4-one [38951-95-8] mp 157—158°C and l,3-dichloro-2,2,5,5-tetramethylimidazohdin-4-one [128780-87-0] (6), mp 69—71°C (158). In water, these compounds are somewhat less stable but better disinfectants than the oxazoUdinones. They have potential for water disinfection and in hard surface cleaners. l-Bromo-3-chloro- [108602-19-3] mp 102—104°C, and 1,3-dibromo- [108602-18-2] mp 119—121°C, derivatives of 4,4,5,5-tetramethylimidazohdin-2-one have been prepared.
