Abstract

L'invention concerne un inhibiteur de corrosion adapté à une acidification à 200 °C et son utilisation. L'inhibiteur de corrosion pour acidification comprend un composant A. Le composant A comprend, en pourcentages en poids : un produit de condensation aldéhyde-cétone-amine, un sel de quinoléine ammonium quaternaire, un acide organique, un dérivé d'alcynol, un synergiste organique, un solvant alcoolique, un dispersant et de l'eau, le sel de quinoléine ammonium quaternaire étant synthétisé par une réaction quaternaire d'au moins un composé parmi le chlorure de benzyle, l'alcool phénétylique, le phénylbutanol et le chlorure de cétyléthyl benzyle ammonium avec la quinoléine.
