Process for preparing a 5,5'-methylenebis(2-hydroxy-4-alkoxybenzophenone)

A novel process is provided for preparing 5,5'-methylenebis(2-hydroxy-4-alkoxybenzophenone), comprising forming a novel 2-hydroxy-4-alkoxy-5-aminomethylbenzophenone by a reaction of a 2-hydroxy-4-alkoxybenzophenone with an amine and formaldehyde, and causing the 2-hydroxy-4-alkoxy-5-aminomethylbenzophenone to react with a 2-hydroxy-4-alkoxybenzophenone or to dimerize. Both the aminomethylhydroxyalkoxybenzophenone and the methylenebis (2-hydroxy-4-alkoxybenzophenone) which are prepared according to this invention are useful to prevent photo-degradation of organic materials, particularly as light stabilizers for synthetic resins.
