Abstract and Summary High yields (85%) of 6‐fatty acid esters of l ‐ascorbic acid were obtained by reacting l ‐ascorbic acid (1.2 M) in 98~99% sulfuric acid for 36 hr at 20 C with 36% excess fatty acid. In concentrated sulfuric acid, l ‐ascorbic acid was rapidly sulfated to produce mainly l ‐ascorbyl 6‐sulfate, which slowly reacted with fatty acid to produce l ‐ascorbyl 6‐acylate.
