Abstract: The present invention relates to an integrated process for synthesizing dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate and a process for impregnating the dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate on to inert carrier granules. The process involves adding dimethyl phosphite to a reaction mixture containing chloral under anhydrous, inert conditions. The molar ratio of chloral to dimethyl phosphite used in the reaction mixture is from about 1.0:1.0 to about 1.1:1.0. The impregnation process involves transferring molten dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate into a process vessel and discharging weighed aliquots into a formulation vessel to form a granular product containing dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate.

Abstract: The preparation of .alpha.-carbonylphosphine oxides by oxidizing an .alpha.-hydroxyalkyl phosphine oxide with an organic hydroperoxide or of an organic peroxy acid in the presence of a compound of a Group IV to Group VIII metal in the periodic table, and novel .alpha.-hydroxybenzyl phosphine oxides..alpha.-Carbonylphosphine oxides are used as photoinitiators for polymerizable compositions.
