ABSTRACT:
N-Monosubstituted 2'- or 4'-amino-4-alkoxy-diphenyl ethers, where the N-substituent is an arylmethyl group, are effective antioxidants in a wide variety of petroleum products and petroleum related products. Within the class of arylmethyl groups, heteroaryl groups are especially desirable, as exemplified by pyridinylmethyl and thienylmethyl.
