Paragraph 0051; 0054-0056, (2020/08/09)
The invention discloses methacrylate modified organosilicon quaternary ammonium salt as well as a preparation method and application thereof. The methacrylate modified organosilicon quaternary ammonium salt disclosed by the invention simultaneously has a siloxane group, a cationic quaternary ammonium group and a methacrylate group, can achieve functions of a silane coupling agent, enhances the bonding strength and durability of the prosthesis, and can endow the bonding interface with an antibacterial function through the cationic quaternary ammonium group, thereby effectively avoiding secondary caries and obviously improving the long-term treatment effect of bonding repair. The methacrylate-modified organosilicon quaternary ammonium salt comprises the following structure shown in the specification.
Integrated approach to surfactant environmental safety assessment: Fast atom bombardment mass spectrometry and liquid scintillation counting to determine the mechanism and kinetics of surfactant biodegradation

Fast atom bombardment man spectrometry and liquid scintillation counting have been used to study the biodegradation of a novel cationic surfactant In live sludge. The rates of primary biodegradation and the extent of complete miner allzation were determined. Furthermore, an Intermediate degradation product was Identified and Its rates of formation and subsequent removal have been established. These data find utility In assessing the environmental safety of the surfactant and the accuracy of various environmental fate models.
