Various kinds of aliphatic alcohol esters of gallic acid were synthesized, especially two new compounds, decyl. ester (mp. 81-83°) and cetyl ester (mp. 84-84.50°). The protective effects on the oxidation of fat by these esters were compared on the basis of quantities of peroxide produced and the weight increased. Some differencies between the quantities of peroxide produced were recognized even in the same ester applied to one sort of fat as the material but, generally, all the esters indicated considerable protective effects. In gravimetry, decrease of weight was found in some esters. All esters indicated the excellent effect. It was summarized on the basis of the effects by both the methods that the protective effect has no particular relation to number of carbons in alcohols C2 to C18, but that iso-type seems to indicate a more powerful effect than normal-type. Generally, ethyl-, isopropyl- and isobutyl ester indicated the fairly excellent effect.
