الإجراء التجريبي

Behenic acid manufactured by Henkel Co. (trade name: Edenor C22-85R) in an amount of 100 kg was admixed with 1200 kg of isopropyl alcohol, and dissolved at 50° C. The mixture was filtrated through a 10 μm filter, and cooled to 30° C. to allow recrystallization. Cooling speed for the recrystallization was controlled to be 3° C./hour. The resulting crystal was subjected to centrifugal filtration, and washing was performed with 100 kg of isopropyl alcohol. Thereafter, the crystal was dried. The resulting crystal was esterified, and subjected to GC-FID analysis to give the results of the content of behenic acid being 96 mol %, lignoceric acid 2 mol %, and arachidic acid 2 mol %. In addition, erucic acid was included at 0.001 mol %.
