4,5-Difluorophthalonitrile - Introduction
4,5-Difluoro -1,2-benzonitrile is an organic compound with the chemical formula C8H3F2N. The following is a description of its nature, use, preparation and safety information:
Nature:
4,5-Difluoro -1,2-benzonitrile is a colorless crystal with a bitter almond taste. It is stable at normal temperature and pressure and is not volatile. Its solubility is low and its solubility in water is small.
Use:
4,5-Difluoro -1,2-benzonitrile plays an important role in organic synthesis. It can be used as an intermediate in the pharmaceutical industry to synthesize drugs, pesticides and other organic compounds. In addition, it can also be used as a synthetic raw material in the fields of coatings, dyes and plastics.
Preparation Method:
The preparation method of 4,5-difluoro -1,2-benzonitrile can be obtained by decarboxylation reaction of phthalic acid. First, phthalic acid is reacted with ferrous fluoride and anhydrous hydrofluoric acid to produce isophthalic acid. The isophthalic acid is then converted to 4,5-difluoro -1,2-phthalonitrile by cyanation.
Safety Information:
4,5-difluoro -1,2-benzonitrile has low toxicity, but it is still necessary to pay attention to safe use. During operation, contact with skin and eyes should be avoided to prevent irritation and damage. At the same time, it should be used in a well-ventilated area and use personal protective equipment, such as gloves, goggles and protective clothing. During storage and transportation, contact with oxidizing agents and strong acids should be avoided to avoid dangerous situations. In case of accidents, corresponding emergency measures shall be taken immediately and professional assistance shall be consulted.
