| description | The present invention relates to highly concentrated, anhydrous amine salts of hydrocarbon polyalkoxy sulfates, wherein the salts are selected from the group of substituted amines, preferably alkanolamines. The products obtained are of low viscosity and pumpable at room temperature. Due to the absence of water, the salts are highly resistant to hydrolysis, even at high temperatures. The invention further relates to the use of the compositions according to the invention in an aqueous dilution for use in oil reservoirs with the aim of achieving enhanced oil production, or for the recovery of hydrocarbons from tar sands or other surfaces or materials provided with hydrocarbon.
L'invention concerne des sels d'amines anhydres, très concentrés, de polyalkoxysulfates d'hydrocarbures, les sels étant choisis dans le groupe des amines substituées, de préférence des alcanolamines. Les produits obtenus sont peu visqueux et pompables à température ambiante. En raison de l'absence d'eau, les sels sont très stables à l'hydrolyse, même à des températures élevées. L'invention concerne également l'utilisation des compositions selon l'invention sous forme diluée aqueuse pour un usage dans des gisements pétrolifères, avec pour but d'obtenir une meilleure extraction du pétrole ou d'extraire des hydrocarbures de sables bitumineux ou d'autres surfaces ou matières contenant des hydrocarbures. |
