Versuchsvorschrift
In an exemplary embodiment, 20 mmol ethanolamine was reacted with 1 mmol vinyl stearate at 80° C. for 1 hour in the presence of 1% sodium methoxide. N-stearoylethanolamine with 96% purity was obtained after the removal of excess ethanolamine without further purification. In another exemplary embodiment, 20 mmol ethanolamine was reacted with 1 mmol vinyl palmitate at 60° C. for 1.5 hours in the presence of 1% sodium methoxide. N-palmitoylethanolamine with 98% purity was obtained after the removal of excess ethanolamine without further purification. More examples of reacting the alkanolamine and the vinyl ester of the fatty acid to prepare the high-purity fatty acid N-acylalkanolamine in a high yield are described in Examples 1-8.
