Disclosed are selected N,1-disubstituted hydrazinecarboxamides having the formula
wherein R1 is selected from the group consisting of alkyl containing from 1 to about 20 carbon atoms, aromatic containing from about 6 to about 12 carbon atoms, and cycloalkyl containing from about 5 to about 10 carbon atoms, and wherein R2 is selected from the group consisting of alkyl containing from 1 to about 20 carbon atoms and hydroxyalkyl containing from 2 to about 20 carbon atoms. These compounds have utility as antioxidants for a variety of organic compounds subject to oxidative degradation, including functional fluids such as petroleum fuels and lubricants. Selected hydrazinecarboxamides having the aforesaid formula are also novel compounds.
