Novel compounds are described, being alkylated diphenylamine derivatives of triazole, wherein the alkyl group on at least one of the phenyl groups is C8 or higher, in an amount ranging from 0.001 to 5.0% by weight of the lubricating composition. In particular, the derivatives may be
1-[di-(4-octylphenyl)aminomethyl]triazole;
1-[di-(4-nonylphenyl)aminomethyl]triazole;
1-[(4-octylphenyl)(4-butylphenyl)aminomethyl]triazole; and
1-[(4-octylphenyl)(phenyl)aminomethyl]triazole.
A lubricating composition comprising the novel derivatives is also disclosed.
A highly efficient and practical oxidative dearomatization of phenols using sodium hypochlorite pentahydrate as an inexpensive, strong oxidant is reported for the first time. The oxidation reactions proceeded very rapidly in the presence of water to give the desired products in excellent yields, and sodium chloride and water were the only by-products derived from the oxidant.
A high-performance enantioselective quaternary ammonium hypoiodite catalysis was developed for the dearomatization of arenols using oxone as an environmentally benign oxidant. The oxidation of not only 1- and 2-naphthols but also phenols, which were hardly reactive using the previous hypoiodite catalysis, readily proceeded under mild conditions, and only inorganic wastes were generated from the oxidant

A mixture of a polyester or a polyamide, such as poly(ethylene terephthalate) PET, and a suitable stabilizer selected from the group consisting of certain Mannich base compounds, when extrusion compounded exhibits a lower residual acetaldehyde content than does PET or polyamide alone when similarly treated. The invention pertains to any polyester or polyamide used in the manufacture of molded articles, fibers, or films, for instance bottles or containers which are used to store consumer materials, for example food, beverages and water.

A phosphite of formula (I):
wherein R1, R2, R4 and R5 represent hydrogen atom, an alkyl group, a cycloalkyl group, an alkylcycloalkyl group, an aralkyl group or a phenyl group; R3 represents hydrogen atom or an alkyl group; X represents a direct bond, sulfur atom, or a -CHR6- group in which R6 represents hydrogen atom, an alkyl group or a cycloalkyl group; A represents an alkylene group having 2 to 8 carbon atoms or a *-COR7-group in which R7 represents a direct bond or an alkylene group, and * indicates the bond to the oxygen; and one of Y and Z represents a hydroxyl group, an alkoxy group or an aralkyloxy group and the other one represents hydrogen atom or an alkyl group, is suitably used as a stabilizer for an organic material.
