Methyl octadecatrienoate was isolated by fractional precipitation of the brominated glycerides and its methyl esters in organic solvents, and by fractional distillation of the methyl esters.
This methyl octadecatrienoate had d254 0.9072, n25D 1.4745, M.RD. 90.53, S.V. 191.7, I.V. (Wijs) 261.7.
Oxidation of methyl octadecatrienoate in acetone with KMnO4 gave monomethyl adipate, butyric acid and succinic acid. This indicates following formula for octadecatrienoic acid.
CH3 (CH2) 2CH=CH (CH2) 2CH=CH (CH2) 2CH=CH (CH2) 4COOH.
