Preparation of N-Methyl Linseed Oil Fatty Acid Amide

Preparation of N-Methyl Linseed Oil Fatty Acid Amide 

Ten grams of linseed oil and 10 g. of methylamine are stirred in an autoclave at room temperature for 240 hours. 

After the reaction is over, the reaction mixture is poured into a mixture of 1 N hydrochloric acid and ice, and subjected to extraction with ethyl ether. 

The ether layer is washed successively with 5% hydrochloric acid, 5% sodium carbonate aqueous solution and water, and then dried over sodium sulfate. Upon evaporation of ether, the residue is subjected to fractional distillation in vacuo, thereby to yield 8.9 g. of N-methyl linseed oil fatty acid amide, B.P. 178-190° C./0.03 mm. Hg, I.R. 1,650 cm.-l. (I.R. means wave number of the infrared absorption spectrum.)
