Abstract: Tetraphenylborates are obtained in an industrially advantageous grade by spray drying an organic, aqueous or organic-aqueous extract of the tetraphenylborates obtainable in the tetraphenylborates synthesis. It is advantageous to treat the specified extract prior to spray drying with pH-controlling auxiliaries and adsorbents to remove byproducts or to limit their formation. The process gives tetraphenylborates in a homogeneous technical grade, i.e. in a narrow particle size distribution and in a particular particle shape, which improves the dispersibility in the medium to be used.
