Introduction
Acid is an organic compound with the chemical formula C7H7NO2. It is a colorless crystalline solid, soluble in water and organic solvents.
Acid has a variety of uses. It can be used as an intermediate in organic synthesis for the preparation of other compounds. It can also act as a ligand for organometallic complexes and participate in catalytic reactions. In addition, it can also be used in the synthesis of certain pharmaceuticals.
There are many ways to prepare the ICT. One common method is synthesis by treatment and oxidation of toluene. Specifically, toluene is first reacted with acetaldehyde in the presence of an oxidizing agent to produce 3-methyl-4-picolinic acid ester, which is then subjected to acid hydrolysis to obtain the target product.
The safety of acid is high, but some safety matters still need to be paid attention. Wear appropriate protective equipment such as goggles and gloves during operation. Avoid inhaling the resulting dust and gas and avoid contact with the skin. During storage and transportation, attention should be paid to moisture-proof, fire-proof and explosion-proof measures. In case of accidental ingestion or contact, seek medical advice immediately and bring the safety data sheet of this product to the hospital.
