| Hazard Information | Back Directory | [Uses]
Octamethylcyclononasiloxane is employed as a antibacterial agent. It is particularly effective against marine Bacillus cereus. | [Synthesis]
Hydrogen-containing double capsule (134.0g, 1mol) and octamethylcyclotetrasiloxane (519g,1.75mol) mixture was added dropwise to a vigorously stirred 10% solution of potassium hydroxide in water and toluene to control the temperature to within 50 degrees C |
