To a stirred solution of 567 g. (2.1 mols) of octadecyl alcohol and 212 g. (2.1 mols) of triethyl amine in 1800 ml. of toluene, at 30° C., there is added a solution of 265 g. (1.0 mol) of dichloropentaerythritol diphosphite in 600 ml. of toluene; the addition is made portionwise over a period of one hour, then the mixture is warmed with continued stirring at 45°-50° C. The cooled mixture is filtered to separate the triethylamine hydrochloride and the filtrate is stripped of toluene to a final temperature of 85° C./20 mm. The solid residue consitutes a quantitative yield of distearyl pentaerythritol diphosphite, M.P., 68°-70° C.
