3,6-di-t-butyl-2-naphthyl catechol phosphite is readily prepared by the reaction of catechol phosphorodichloridite and 3,6-di-t-butylnathphol in the presence of a trialkyl amine in a solvent. The 3,6-di-t-butyl-2-naphthyl catechol phosphite is an excellent stabilizer for polymers, including polypropylene, and forms synergistic combinations with hydroxyphenylalkyleneyl isocyanurates that provide excellent resistance to polymer breakdown during processing.
