The 2-alkyl-6-t-butyl-4-(pentamethylbenzyl)phenols in which the 2-alkyl group is t-butyl or methyl are novel compounds having melting points sufficiently low to make them attractive as antioxidants for low melting polymers such as polyethylene, polypropylene, and polystyrene.

Phenolic antioxidants and stabilized organic compositions

Antioxidant compounds having the structure: ##STR1## in which p is 1 or 2 and + is a tert-butyl group provide excellent oxidation stability, melt flow index and yellow index, especially in polypropylene.

Antioxidant

A process for preparing unsaturated organic compounds by reacting an allylic alcohol and a ketone or aldehyde, in the presence of carbon monoxide and a Group VIII metal salt/germanium or tin salt combination catalyst is described. The unsaturated organic compounds are principally unsaturated alcohols having a molecular weight greater than the allylic alcohol reactant.
