The nature of the copper oleate

Copper oleate acerbic is a blubbery acid. MF C4H9 (CH = CH) 3 (CH2) 7COOH. Also accepted as Tong acid, the accurate name is cis, trans, auto -9,11,13 - octadecadienoic acid. Tung oil in the anatomy of glycerides, accounting for 87% of the glycerides of blubbery acids in the absolute content. The eleostearic acerbic is the a lot of important isomers of linolenic acid. The eleostearic acerbic molecules accept three conjugated bifold bonds, there are a array of cis and auto isomers, which a-eleostearic acid, β-eleostearic acid, the a lot of important. Referred to as a body, the by itself occurring eleostearic acerbic is cis, trans, trans-isomer; beta physique is a trans, trans, auto isomer. a-eleostearic acerbic as white crystals; mp 49 ° C, the baking point of 235 ° C (12 mm Hg), while decomposition, the about body of 0.9028 (50/4 ℃); Specific circling [a] D-5.8 °; attenuated in booze and ether. β-eleostearic acerbic as a leaf-shaped crystals; mp 71 to 72 ° C, baking point of 188 ° C (1 mm Hg), the about body of 0.8839 (80/4 ℃); was attenuated in booze and ethanol. a isomer by ablaze or heat, or during storage, can be partially adapted to the β-isomer. The tung oil acerbic and maleic anhydride accident diene accession acknowledgment of circadian products. The tung oil stearic acerbic hydrogenation generate; role of bromine generated the four boiler beneath ultraviolet ablaze to accomplish six bromide.
