4021-08-3 - Introduction
Acid (acid) is an organic compound. Its chemical formula is C7H7NO2, and its chemical structure is composed of a pyridine ring and a formic acid group.
The following are some properties of acid:
-Appearance: White crystal or powder
-Melting point: 127-130°C
-Boiling point: 361.1°C
-Solubility: Soluble in water, ethanol, chloroform and other organic solvents
One of the main uses of m acid is as an intermediate compound in organic synthesis. It can be used to synthesize various valuable organic compounds, such as pesticides, drugs, dyes, etc. In addition, it can also be used as a reagent for biochemical research and laboratory analysis.
The preparation method of Li acid is usually obtained by oxidizing picoline. Specifically, picoline and potassium permanganate solution are first reacted, and then the reaction product is acidified to obtain the target product.
When using and handling acid, pay attention to the following safety information:
-It is an organic compound that can cause irritation and damage to the skin, eyes and respiratory tract. During operation, protective gloves, safety glasses and face mask should be worn to avoid contact with skin and inhalation of vapors.
-During storage and transportation, it should be kept in a cool, dry and well-ventilated place, away from fire and oxidizing agents.
-When disposing of waste, comply with local regulations to ensure proper disposal and avoid harm or pollution to the environment.
