trans,trans-2,4-Heptadienal Usage And Synthesis

Description	2,4-Heptadienal retards or prevents the development of "off-flavors" in auto-oxidizing fats and oils. May be prepared by reduction with LiAlH4 of the dienoic acid prepared by the Doebner synthesis, followed by oxidation with Mn02 of the resulting dienol to the corresponding dienol; by the method of Marshall and Whiting.
Chemical Properties	2,4-Heptadienal has a fatty, green odor In auto-oxidizing fats and oils, it retards or prevents the development of “off-favors ”.
Chemical Properties	clear yellow liquid
Chemical Synthesis	By reduction with LiAlH4 of the dienoic acid prepared by the Doebner synthesis, followed by oxidation with MnO2 of the resulting dienol to the corresponding dienol; by the method of Marshall and Whiting.
