29640-98-0 - Introduction
acid is an organic compound whose chemical formula is C8H6FNO4. The following is a description of its nature, use, preparation and safety information:
Nature:
-acid is a white crystalline solid with a pungent odor.
-Its melting point is 112-116 degrees Celsius.
-At room temperature, it is in a solid state.
Use:
-must acid can be used as a synthetic intermediate in organic synthesis.
-It can be used to prepare other organic compounds, such as pesticides, drugs and dyes.
Method:
-The preparation method of acid is to react 2-nitrophenylacetic acid with hydrofluoric acid.
-First, dissolve 2-nitrophenylacetic acid in anhydrous hydrofluoric acid and place it at low temperature.
-Then, add nickel fluoride as a catalyst, and continue the low-temperature stirring reaction for a period of time.
-After completion of the reaction, dilute the mixture with water and neutralize hydrofluoric acid.
-Finally, separate and dry by crystallization to obtain white crystals of acid.
