Definitions

  • Tetrafluoroborate is an anion.
  • Example 2 The title compound was analogous to Example 2 from 4-methoxyphenacylpyridinium bromide and sodium tetrafluoroborate in a yield manufactured by 85%.
  • the toner was almost completely removed from the carrier particles by means of a strong air flow (approx. 4,000 cm 3 / min) and simultaneous suction, the latter remaining in the measuring cell.
  • the charge on the carrier was registered on the electrometer. It corresponded to the amount of charging of the toner particles, but with the opposite sign. The amount of q with the opposite sign was therefore used to calculate the q / m value.
  • the mass of blown-off toner was determined by weighing the measuring cell back and the electrostatic charge q / m was calculated therefrom.
