| titleOfInvention | IMPROVED PROCESS FOR THE OBTAINING OF ESTERS OF IONIC AMINO ACIDS |
| abstract | A process of synthesis of ionic amino acid esters, using a pressure reactor that is nothing more than a glass or steel reactor with a venting attachment. And that allows to develop chemical reactions under pressure without risk of explosion giving high yields compared to conventional methods of synthesis such as pressurized flasks, ultrasound and microwaves. These compounds are of great interest for having a wide variety of applications, and in particular although not exclusively, they can be used as biotensoactive for the breakdown of emulsions oil in water, water in oil, mixed; or in the washing of the crude oil contained in contaminated soils. Ionic amino acid esters can be obtained in a single stage or one pot reaction by simultaneous esterification and protonation of the amino group to generate an ammonium group cation. Additionally, a minimum amount of waste is generated, since all reagents are part of the product, its purification being simpler or unnecessary since it has an economy of atoms between 88-95% according to the principles of Green chemistry. Claim 1: An improved process for obtaining ionic amino acid esters, characterized by the synthesis route [1] wherein: R¹ and R² represent aliphatic or branched chains of functionalized alkyl, alkoxy or alkyl groups: R¹ represents an aromatic or heterocyclic group from 1 to 10 carbon atoms, preferably from 1 to 6 carbon atoms giving the corresponding amino acid, R² represents an aromatic, heterocyclic, branched or aliphatic chain of 6 to 20 carbon atoms with or without unsaturations, preferably from 8 to 18 carbon atoms, X represents a fragment of the organic acid type carboxylate, mesylate, sulfonate or tosylate among others, preferably mesylate and tosylate; and consisting of a single reaction stage: a) reacting an unprotected natural or synthetic amino acid (1) with an aromatic or aliphatic fatty alcohol (2) of odd or even number of 6 to 20 carbon atoms, in stoichiometric amounts , in the presence of an organic acid (HX) carboxylate, mesylate, sulfonate or tosylate type among others, used as a catalyst, under conventional heating (CC) for 1 to 3 hours, at a temperature of 60 to 150 ° C and pressure of 0 to 250 psi; The product obtained is allowed to cool and recrystallized from ethanol. |
