9-Octadecenoic acid, anhydride, (E,E)-

Description:
9-Octadecenoic acid, anhydride, (E,E)-, also known as elaidic anhydride, is a chemical compound derived from oleic acid. It is characterized by its long carbon chain, consisting of 18 carbon atoms with a double bond in the trans configuration at the 9th position. This structure contributes to its unique physical and chemical properties, including its relatively high melting point compared to saturated fatty acids. The anhydride form indicates that it is a derivative formed by the dehydration of the corresponding acid, resulting in a cyclic structure that can participate in various chemical reactions, such as esterification and polymerization. It is typically a colorless to pale yellow liquid with a characteristic fatty odor. This compound is used in various applications, including the synthesis of surfactants, lubricants, and as an intermediate in organic synthesis. Its reactivity and stability make it a valuable substance in both industrial and research settings. Safety data should be consulted for handling and exposure guidelines, as with all chemical substances.
