Reaktionsschritte
Mixed with 120 kg of isopropyl alcohol was 100 kg of behenic acid (trade name Edenor C22-85R), manufacture by Henkel Co., dissolved at 50° C. and filtered employing a 10 μm filter. Thereafter, the temperature was lowered to 30° C. and recrystallization was performed. The cooling rate during recrystallization was controlled to be 3° C./hour. The resulting crystals were subjected to centrifugal filtration, were washed with 100 kg of isopropyl alcohol, and subsequently dried. The resulting crystals then underwent esterification. Subsequently, GC-FID was performed, resulting in a silver behenate proportion of 99 percent and a lignoceric acid proportion of 0.5 percent, and an arachidic acid proportion of 0.5 percent as other products.
