摘要
Process for producing an alkali and/or alkaline earth metal hydroxide adduct of a triarylborane from the amine adduct thereof which comprises reacting an aqueous mixture of said amine adduct with an alkali and/or alkaline earth metal hydroxide at elevated temperature, e.g., 60-130 DEG C, removing substantially all of the amine liberated during the reaction, e.g., by stripping with an inert gas and thereby forming the metal hydroxide adduct of said borane. The process is preferably applied to the ammonia adduct of triphenylborane which adduct is generated in the treatment of a waste stream from the hydrocyanation process. Sodium is the preferred metal because the sodium hydroxide adduct is an intermediate in the production of triarylboranes which are useful as catalyst promoters.
