Using sodium fluoborate or ammonium fluoborate,1 boric oxide, and sulfuric acid, the yields are good, little silicon fluoride is produced, and the residue is water soluble. [Pg.21]

This product is pure enough for use in preparing boron trifluoride. If a clean, pure preparation of ammonium fluoborate is required for another purpose, the best way to make it is to mix the theoretical amounts of ammonium acid fluoride and boric acid in aqueous solution in a plastic dish, and evaporate to crystallization on a steam bath. ...

The generating flask A has a volume of 500 ml. The test tubes P, C, and D are 25 X 200 mm. B is empty and used as a trap C contains some 30 ml of sulfuric acid saturated with boric acid, to absorb hydrogen fluoride from the gas stream. In A, place the entire product of ammonium fluoborate, well mixed with 6 grams of finely powdered boric oxide. In D, place 30 ml of diethyl ether, and cool the tube in ice. Arrange for the gas passing out of D to be sucked away by the draft or to be absorbed in caustic soda as in Experiment 1. [Pg.101]

BF3MEA is extremely water soluble and will readily absorb water on exposure to moist air, slowly forming ethyl ammonium fluoborate and hydroxyfluoborates. Hence, it is advisable to store in small containers, which will need to be opened only once or twice. Butanone-2 (MEK) is a preferred solvent since acetone generally contains water. [Pg.518]

Cyclic voltammetry can be used to estimate the charge transfer rate and also evaluate how this rate depends on parameters such as morphology and the chemical structure. The cyclic voltammetric examination of electroactive polymers is usually done in monomer-free solutions containing only the solvent and supporting electrolyte. In order to avoid the complication of mixed electrolytic equilibria, the supporting electrolyte and the solvent are usually the same as employed for the polymerization. Figure 3 shows the cyclic voltammogram (CV) of a polypyrrole film prepared in acetonitrile/tetra-w-butyl ammonium fluoborate medium. The anodic peak corresponds to polypyrrole oxidation, while the cathodic one corresponds to the reduction of this species. [Pg.109]
