Abstract The addition of diethylhydroxylamine (DEHA) to the urban atmosphere had been suggested as a means of preventing photochemical smog. Smog chamber studies were carried out to investigate the photochemical smog formation characteristics of irradiated hydrocarbon-nitrogen oxides - DEHA mixtures. Propylene and n-butane were the hydrocarbons used. The effects of DEHA upon ozone formation, aerosol formation, peroxyacetyl nitrate formation, nitric oxide-to-NOx conversion, and hydrocarbon consumed are described. The rate constant for the reaction DEHA + OH yields to products was estimated as 4.1 + or - 3.4 X 10 to the 5th power/ppm/min. Possible reaction schemes for DEHA in the photochemical smog mechanism are discussed. The addition of DEHA to a HC/NOx system inhibits the conversion of NO to NO2 during the initial minutes of irradiation, but after continued irradiation accelerates this conversion.
