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.
