Reaction Steps

In one specific embodiment of the present disclosure, 20 ml of 1-heptanol, 1 mmol of galactaric acid, 0.05 mmol of methyltrioxorhenium catalyst, and 0.05 mmol of para-toluenesulfonic acid were poured into a 50 cc reactor. The temperature in the reactor was then raised to 150° C. and the reaction was performed for 12 hours, maintaining the reactor temperature at 150° C. to obtain diheptyl galactarate.
