1,2-双(4-吡啶基)乙烷 - Introduction
1,2-Bis(4-pyridyl)ethane is an organic compound with the chemical formula C12H12N2. The following is a description of its nature, use, preparation and safety information:
Nature:
1,2-Bis(4-pyridyl)ethane is a colorless crystal that can be dissolved in most organic solvents, such as ethanol, acetone and benzene. It has a lower melting point and boiling point.
Use:
1,2-Bis(4-pyridyl)ethane has a wide range of applications in coordination chemistry. It can be used as a ligand to form coordination compounds with transition metal ions for catalytic reactions, fluorescence analysis, and synthesis of porous materials.
Preparation Method:
The method for preparing 1,2-Bis(4-pyridyl)ethane is relatively simple and is generally carried out through the following steps:
1. First, 4-pyridinecarboxaldehyde is reacted with ethylenediamine in a suitable solvent to generate 1,2-bis (4-pyridine) ethanol.
2. Next, 1,2-bis (4-pyridyl) ethanol and pyrophosphoric acid under acidic conditions are subjected to condensation reaction to obtain 1,2-Bis(4-pyridyl)ethane.
Safety Information:
1,2-Bis(4-pyridyl)ethane is relatively safe under general conditions, but the following matters still need to be paid attention:
1. Avoid contact with skin, eyes and respiratory tract. Wear appropriate personal protective equipment, such as safety glasses, gloves and protective masks.
2. avoid inhaling gas, fly ash or steam. Good ventilation equipment and environment should be ensured during operation.
3. Store away from fire and oxidizing agents, store in a sealed container, and avoid exposure to direct sunlight.
4. Follow local safety procedures and laws and regulations during use or disposal.
Please note that the correct laboratory operation methods should be followed when using chemicals, and do not try to synthesize or handle toxic or dangerous substances without professional guidance.
