Abstract
Official abstract text for this publication.
Base compounds including 1,3-oxazinan-6-one derivatives of N-alkyl or N-alkenyl or N-cycloalkyl or N-aryl propionic acids and paraformaldehyde, and their application as corrosion inhibitors with multifunctional properties serving as inhibitory/dispersant of asphaltene in production processes, transportation, refining and storage of crude oil and derivatives. The corrosion inhibitor with inhibitory/dispersant of asphaltenes properties comprises an active substance base of 1,3-oxaninan-6-ones and hydrocarbon solvents such as benzene, toluene, mixed xylenes, o-xylene, m-xylene and p -xylene, diesel, kerosene, jet fuel, alcohols, aliphatic branched and unbranched alcohols containing from 3 to 10 carbon atoms, such as isopropanol, butanol and pentanol, and mixtures of hydrocarbon solvents with aliphatic branched or unbranched liquid fuels. In addition, a process for obtaining 1,3-oxazinan-6-ones derivatives of N-alkyl or N-alkenyl or N-cycloalkyl or N-aryl propionic acids and paraformaldehyde is described.
First claim
Opening claim text (preview).
What is claimed is: 1. A multifunctional corrosion inhibiting composition comprising a 1,3-oxazinan-6-one with corrosion inhibitory properties and capable of dispersing heavy organic compounds in crude oil, said 1,3-oxazinan-6-one present in an amount of 10 to 90% by weight, and a hydrocarbon solvent in an amount of 10 to 90% by weight, where said amounts are based on the total weight of said composition; wherein the 1,3-oxazinan-6-one has the following molecular structure:…
