Preparation method of tetraphenylborate

The invention discloses a preparation method of tetraphenylborate. Sodium tetraphenylborate reacts with a quaternary salt compound under the synergistic effect of water and an organic solvent to prepare a tetraphenylborate product, and the organic solvent is an organic solution which can dissolve the quaternary salt compound and does not participate in the reaction. According to the method, the process of almost quantitatively reacting sodium tetraphenylborate with the quaternary salt compound in a mixed reaction system consisting of water and an organic solution to obtain an organic quaternary tetraphenylborate product is realized, the product purity is high, and the byproduct sodium salt is completely dissolved in water, so that interference byproducts are avoided, the method is suitable for efficient and high-purity large-scale preparation and production of organic tetraphenylborate.

Medical devices having improved antimicrobial/antithrombogenic properties

An enhanced antimicrobial antithrombogenic medical device is formed by using an oligodynamic metal and a noble metal with a polymer, and forming the mixture into a device. By using low concentrations of conductive polymers or ionophoric compounds, non-conductive, or highly plasticized polymers can be likewise blended into an iontophoretic-capable composition. The surface of the device may be treated with a solvent to remove the top surface of the polymer and create surface voids in the composition in order to expose previously encapsulated iontophoretic materials. This surface treatment results in a larger reaction area of the iontophoretic capable composition that produces larger yields of bacteriostatic oligodynamic ions for a longer duration thereby increasing the antimicrobial effectiveness of the composition. The surface of the antimicrobial composition may be treated with an anticoagulant such as heparin or heparin complexed with a quaternary ammonium salt for an added bacteriostatic effect.

[MPh4][BPh4], M = P, As and Sb

The structures of [MPh4][BPh4], M = P, As and Sb, crystallize in a superstructure (I4, Z′ = 1/2) of the P421 c, Z′ = 1/4, structure known for MPh4, M = C, Si, Ge, Sn and Pb. The arrangement of the ions is the same as for CaWO4 (scheelite; I41/a, Z′ = 1/4), which is typical of many other ionic XYO4 structures. Crystals of [MPh4][BPh4] turn a pinkish amber when exposed to UV light; ESR spectra confirm that free radicals are generated.
