2-Fluorocinnamic acid - Reference Information
| solubility | insoluble in water, soluble in organic solvents such as ethanol and ethyl acetate |
| Use | O-fluorocinnamic acid is used as a research compound. |
| There are many methods for preparing | to synthesize o-fluorocinnamic acid, such as Perkin method, Knoevenagel method, o-fluorobenzaldehyde-acetone method, o-fluorobenzaldehyde-ketene method, o-fluorobenzaldehyde-acetic acid method, styrene-carbon tetrachloride method, styrene-carbon monoxide method, Styrene-carbon dioxide method, phenylchloromethane-anhydrous sodium acetate method, halogenated benzene-acrylic acid method, cinnamaldehyde oxidation method, etc. Most of the above methods have no practical industrial application value due to factors such as high energy consumption, heavy pollution, high cost, and low yield, or have been eliminated. At present, the methods of producing o-fluorocinnamic acid in industry are mainly Perkin method and styrene-carbon tetrachloride method. Based on the classification of reaction materials, the synthesis progress of o-fluorocinnamic acid was reviewed and evaluated. |
| storage method | o-fluorocinnamic acid should be stored separately from oxidants and edible chemicals, and should not be mixed storage. Store in a cool, ventilated warehouse. |
