ABSTRACT:
A novel process is provided for preparing a methylenebis(2-hydroxy-4-alkoxybenzophenone), comprising forming a novel 2-hydroxy-4-alkoxyacyloxymethylbenzophenone by a reaction of a 2-hydroxy-4-alkoxybenzophenone with a carboxylic acid and formaldehyde, and causing the 2-hydroxy-4-alkoxyacyloxymethylbenzophenone to react with a 2-hydroxy-4-alkoxybenzophenone in the presence of an acid catalyst.
Both the acyloxymethylhydroxyalkoxybenzophenone and methylenebis(2-hydroxy-4-alkoxybenxophenone) which are prepared according to this invention are useful to prevent-degradation of organic materials, particularly as light stabilizers for synthetic resins.
