Introduction
Acid (acid) is an organic compound. It has a chemical formula of C6H4FNO2 and a molecular weight of 141.1g/mol.
In terms of nature, acid is a white to yellowish solid. It has strong oxidation and corrosion, can be dissolved in some organic solvents such as alcohol and ether, but the solubility in water is poor.
One of the main uses of acid is as an intermediate in organic synthesis. It is commonly used in the preparation of pharmaceuticals, pesticides and other organic compounds. In addition, it can also be used as a ligand of an organometallic complex.
The preparation method of calcium is usually obtained by the following method: First, 2-fluoropyridine is reacted with acetone and aluminum trichloride in dichloromethane to produce 2-fluoropyridine-4-methanone. Subsequently, 2-fluoropyridine-4-methanone was converted to fluoracid via an acid-catalyzed reaction.
Regarding safety information, acid is an organic chemical that may cause harm to human health and the environment. Follow appropriate safety practices during handling and storage to avoid contact with skin, eyes and respiratory tract. Personal protective equipment such as lab gloves, goggles and protective masks should be worn when in use. In addition, it should be stored in a cool, dry place, away from fire and oxidizing agents. If necessary, operate in a well-ventilated environment. In terms of waste disposal, local laws and regulations should be followed.
