Procedure

Dichloro pentaerythritol diphosphite (1 mol) was reacted with 2.05 mol of ABITOL in toluene using 2.1 mol of triethyl amine as an acid acceptor. The very viscous liquid product, bis abietyl pentaerythritol diphosphite, was obtained after filtering the triethylamine hydrochloride and stripping the toluene.
