They were synthesized N-alkyl or N-alkenyl or N-cycloalkyl or 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, from reaction in absence of solvent in a temperature range from 30 to 180 °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, which inhibit ferrous metal corrosion of pipelines and storage tanks and transport crude oil and liquid fuels. Des acides synthétisés N-alkyle, N-alcényle, N-cycloalkyle ou N-aryle amino ou imino propioniques avec une chaîne alkyle possédant de 6 à 18 atomes de carbone ou une chaîne alcényle possédant de 8 à 30 atomes de carbone, à partir dune réaction en labsence dun solvant dans une plage de températures de 30 à 180 °C et une durée de 1 à 10 heures à la pression atmosphérique. Des formulations composées dacides N-alkyle, N-alcényle, N-cycloalkyle ou N-aryle amino ou imino propioniques, de polyéthers dérivés de loxyde de propylène, de loxyde déthylène ou dun copolymère de ceux-ci et un solvant consistant en des composés aromatiques comme du toluène ou du xylène, du diesel, de lessence ou des alcools comme de lisopropanol et de léthanol ou des mélanges de ceux-ci, qui inhibent la corrosion de métaux ferreux des réservoirs de stockage et des pipelines transportant du pétrole brut et des combustibles liquides.
