실험 절차

Esterification of the crude 3,6-dioxaoctanedioic acid was accomplished as follows: To the reaction flask containing 36 g of the crude diacid, was added 110 ml of methanol. This was stirred for 3 days at room temperature after which 15 g of sodium bicarbonate was added and stirred overnight. The mixture was filtered to remove solids. To the liquor was added an additional 10 g of sodium bicarbonate; this mixture was stirred overnight. The mixture was again filtered; the liquor was fractionally distilled.
