Previous studies have reported on introducing fatty acids to the 6-position hydroxy group of 1,5-GL, but as far as we know, there are no reports on introducing fatty acids to all hydroxy groups of 1,5-GL. Therefore, we decided to introduce various linear saturated fatty acids of different lengths into 1,5-GL and compare their physical properties. The selected fatty acids were 10-carbon decanoic acid (capric acid), 12-carbon dodecanoic acid (lauric acid), 14-carbon tetradecanoic acid (myristic acid), 16-carbon hexadecanoic acid (palmitic acid), 18-carbon octadecanoic acid (stearic acid), and 22carbon docosanoic acid (behenic acid), and the acyl chlorides of each were used. However, because there is no commercially available acyl chloride of behenic acid, the acyl chloride was synthesized using thionyl chloride and then used.
