実験手順
Lysine stearate (35.0 g) was suspended in 300 ml of xylene using a 600-milliliter reaction vessel. The suspension was boiled through heating, and water formed through azeotropic distillation was removed outside the system. After it was identified that a stoichiometric amount of water was removed (reaction time 3 hours), the residue was cooled. Crystals precipitated were separated through filtration, and washed with 100 ml of a 50% ethanol solution. The crystals were recrystallized from a sulfuric acid aqueous solution to obtain 28.8 g of Nε-stearoyl lysine (yield 85.9%). This is designated Derivative A.
