| Abstract: | This paper introduces the synthesis of ascorbic palmitate from palmitic acid and ascorbic acid. At first, palmitic acid is esterified and methyl palmitate is obtained. Then ascorbyl palmitate is prepared through methyl palmitate with ascorbic acid. The IR and the refractivity power are identified. The yield of L ascorbic palmitate is 73 %. |
