BRIDGED IMIDAZOLINES AS ENVIRONMENTALLY FRIENDLY CORROSION INHIBITORS

Abstract: environmentally-friendly corrosion-inhibiting compositions and methods of use thereof for corrosion inhibition of metal surfaces used in oil and gas operations are disclosed. corrosion-inhibiting compositions include a mono (meth)acrylated and/or bridged imidazoline corrosion inhibitor, namely a mono (meth)acrylated and/or bridged imidazoline corrosion inhibitor with a molecular weight of at least about 700 da and therefore does not bioaccumulate according to cefas regulations and provides suitable biodegradability.
