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&#xb0; C. and pressure the range of approximately 0 to approximately 250 psi; the product obtained is cooled and recrystallized from ethanol.

Process for obtaining ionic amino acid esters

A process allows working with viscous petroleum referred to as 'heavy and extra heavy crudes' such as 20 to 6&#xb0; API by adding an appropriate biosurfactant to an aqueous phase containing a biosurfactant active compound. The surfactant can be alkyl glycosides, glycerol esters and alkyl betaines. The result is the formation of a stable crude/water emulsion even with salt present therein.
