N-alkyl, N-alkenyl, N-cycloalkyl, N-aryl amino or imino propionic acids with an alkyl chain ranging from 6 to 18 carbons, or alkenyl chain from 8 to 30 carbons, are obtained from a reaction process in the absence of solvent at a temperature range from 30 to 180&#xb0; C. and a time of 1 to 10 hours at atmospheric pressure. Formulations composed of N-alkyl or N-alkenyl or N-cycloalkyl or N-aryl amino or imino propionic acids, polyethers derived from propylene oxide or ethylene oxide or copolymer thereof and a solvent consisting of aromatic compounds such as toluene or xylene, diesel or gasoline or alcohols such as isopropanol and ethanol, or mixtures thereof, are obtained inhibit ferrous metal corrosion of pipelines and storage tanks and transport crude oil and liquid fuels. A method inhibiting corrosion of ferrous metals adds an effective amount of the corrosion inhibitor to a petroleum based material such as crude oil and liquid fuels such as gasoline, diesel fuel, and aviation fuel.

Amino and imino propionic acids, process of preparation and use

The present invention relates to demulsifying and dehydrating formulations of heavy crude oil based block copolymers amine bifunctionalized with low polydispersities. These formulations can contain solvents whose boiling point is in the range from 35 to 200&#xb0; C., preferably: dichloromethane, chloroform, toluene, xylenes, turbosine, naphtha or mixtures thereof.
