Linseed oil fatty acid ethyl ester was heated at 190, 230, and 270°C for 25 hours in the stream of nitrogen. Volatile compounds produced were collected in the ice trap and dry ice-methanol trap.<BR>The volatile compounds were analyzed by gas-liquid chromatography. As a result, <I>n</I>-heptane, <I>n</I>-octane, <I>n</I>-nonane, <I>n</I>-decane, <I>n</I>-undecane, <I>n</I>-tridecane, valeric aldehyde, caproic aldehyde, pelargonic aldehyde, capric aldehyde and lauric aldehyde were detected.<BR>And these volatile compounds were observed about 8% in the residual ester in the case of 190°C heating and about 5% in the case of 230°C and 270°C heating.
