FIELD: chemistry.
SUBSTANCE: described is a method of preparing spherical particles of solid triphenyl boron-pyridine (TPBP) by separately feeding into an intensely stirred reaction zone (i) a stream of pyridine, and (ii) a stream containing a solution of a sodium hydroxide-triphenyl-boron adduct (TPBA), as a result of which total concentration of TPBA in the merged streams ranges from 1 wt % to 6 wt %, and simultaneously removing the product stream from said reaction zone and extracting TPBP particles.
EFFECT: method can be used on an industrial scale.
