ABSTRACT:
Bis(alkylphenyl)pentaerythritol diphosphite is produced by forming a reaction mass from phosphorous trichloride, pentaerythritol, a chlorinated hydrocarbon solvent and a heterocyclic tertiary amine catalyst followed by the addition of an alkylphenol to the reaction mass. The process further features the use of mild conditions.
