Abstract

The invention provides a preparation method of a silica gel immobilized quaternary phosphonium salt. A silica gel type inorganic material is taken as a carrier, and the surface of the carrier is grafted with a quaternary phosphonium salt type sterilization group so as to synthesize a water-insoluble quaternary phosphonium salt. The quaternary phosphonium salt has good sterilization performance, isinsoluble in water, is easy to separate after sterilization, does not have residual poisons, and can be reused after being treated by hydrochloric acid. Furthermore, because an inorganic material such as silica gel is taken as a microcarrier, the defect that an organic polymer serving as the carrier is easily affected can be overcome; the prepared quaternary phosphonium salt has the advantages ofrigid structure, wide carrier source, low cost and better thermal stability; and the prepared quaternary phosphonium salt can be widely applied to sterilization and disinfection of fluid mediums suchas various industrial and civil water as well as preparation of antibacterial materials.

Description

technical field

[0001] The invention relates to a preparation method of a silica gel-loaded quaternary phosphonium salt, which belongs to the field of fungicides, in particular to an insoluble quaternary phosphonium salt. Background technique

[0002] Quaternary phosphonium salt is a new type of cationic fungicide. Since phosphorus is a third-period element, it has a large ionic radius, strong polarization, and strong electropositivity, so quaternary phosphonium salt has good antibacterial properties, broad-spectrum, low toxicity, and stability. It has been widely used as a bactericide and algicide in industrial circulating water systems, a fungicide for oilfield water injection and an agricultural pesticide. Because of its low foam, strong slime stripping ability and wide pH range, it is used as a substitute for traditional quaternary ammonium fungicides in industrial circulating water and oilfield water injection systems.
