20150118104 | CORROSION INHIBITION COMPOSITION FOR PIPELINES, PROCESS OF ELABORATION AND SYNTHESIS - Compounds and compositions are used as corrosion inhibitors for pipelines for crude oil containing water with high salt concentrations. The inhibitors are ionic liquids, imidazoles, benzotriazoles, and mixtures thereof. The composition includes two or more members of the inhibitors with a solvent. The inhibitors reduce corrosion of metallic surfaces of the pipelines containing crude oil having 0.2 and 40 wt % water, 10,000 to 70,000 ppm salt, and 9 to 600 ppm hydrogen sulfide. A synergic effect is provided by two or more different inhibitors. This synergy is derived from interactions with the metallic surface, among themselves or with the corrosive medium depending on the chain length, to inhibit the corrosion with decrease of the formulation dose. The composition can be a ternary formulation of the three families or two components of one family and a third component of a different family. | 04-30-2015 |
20160068471 | PROCESS FOR OBTAINING IONIC AMINO ACID ESTERS - Embodiments of the present invention provide for efficient methods and processes for preparing ionic amino acid esters from a specific synthesis route. The disclosed embodiments consist of a single reaction step: reacting a natural or synthetic unprotected amino acid with an aliphatic, branched or aromatic fatty alcohol of even or odd number of carbon atoms from 6 to 20 with or without unsaturation(s), in stoichiometric amounts, in the presence of an organic acid (HX) like carboxylate, mesylate, tosylate or sulfonate, employed as catalyst and under conventional heating (CC) of 1 to 3 hours at a temperature in the range of approximately 60 to 150° C. and pressure the range of approximately 0 to approximately 250 psi; the product obtained is cooled and recrystallized from ethanol. | 03-10-2016 |
