544-71-8 - Introduction
trans,trans-9,11-Octadecadienoicacid, chemical name trans,trans-9, 11-octadecenoic acid, is a polyunsaturated fatty acid. The following is a brief introduction to the nature, use, formulation and safety information of trans,trans-9, 11-octadecadienoic acid:
Nature:
- trans,trans-9, 11-octadecadienoic acid is a colorless to pale yellow oily liquid.
-Its chemical formula is C18H32O2, and its molar mass is 280.44g/mol.
- trans,trans-9,11-Octadecadienoicacid has two conjugated double bonds, and a single bond is separated in the structure, so it has a "twisted" shape.
-Its melting point is about -54°C and its boiling point is about 229°C.
- trans,trans-9, 11-octadecadienoic acid is insoluble in water and soluble in organic solvents such as ethanol and disulfide.
-It is stable in the air, but easily oxidized.
Use:
- trans,trans-9,11-Octadecadienoicacid is one of the essential fatty acids needed by the human body, which participates in regulating the body's metabolism and maintaining normal physiological functions.
-It is often used in the food industry to make food products rich in polyunsaturated fatty acids, such as vegetable oils, dairy products, baking, etc.
- trans,trans-9,11-Octadecadienoicacid can also be used to make products such as antioxidants, emulsifiers, medicines and cosmetics.
Preparation Method:
- trans,trans-9, 11-octadecadienoic acid can be prepared by hydrogenation reaction.
-A common preparation method is to subject the oil to hydrogen catalytic hydrogenation reaction to partially or completely saturate the unsaturated double bonds, thereby obtaining trans,trans-9,11-Octadecadienoicacid.
Safety Information:
- trans,trans-9,11-Octadecadienoicacid is relatively safe under normal circumstances.
-But in high concentrations, it may cause irritation to the skin and eyes.
-Long-term excessive intake of trans,trans-9,11-Octadecadienoicacid may increase the risk of cardiovascular disease and other health problems.
-When using or handling trans,trans-9,11-Octadecadienoicacid, it is recommended to wear suitable protective equipment and avoid inhalation, intake or contact.
Please note that the above information is for reference only, and the specific use and operation should be carried out according to the actual situation and relevant safety guidelines.
