Abstract
A hydrocarbonaceous liquid stream is modified to contain a minor amount of the amide reaction product of a polyalkylene polyamine and a neo-acid having 5 to 20 carbon atoms, the neo-acid having three alkyl groups on the carbon atom which is in the alpha position relative to the carboxylic group, whereby corrosion of iron and other metals contacted by said stream is significantly reduced.
