The starting materials used in the production of 1,3,5-Tri(m-pyrid-3-ylphenyl)benzene are aniline and acetic anhydride.
Aniline is an aromatic amine that is readily available in the market and is used as a starting material for the production of a variety of chemicals.
Acetic anhydride is an acidic compound that is used as a coupling agent in the reaction process.

The next step in the production process of 1,3,5-Tri(m-pyrid-3-ylphenyl)benzene is the reaction process.
In this step, the aniline and acetic anhydride are reacted in the presence of a solvent, such as CHCl3, to form the desired product.
The reaction is catalyzed by a strong acid catalyst, such as sulfuric acid, and is typically carried out at a temperature of 80-100°C.
The reaction process is exothermic and requires careful monitoring to avoid excessive heat buildup.

After the reaction process is complete, the resulting product is purified to remove any impurities that may have been introduced during the reaction.
This is typically done by washing the product with a solvent, such as water, and then drying it using a desiccant, such as sodium sulfate.
The purified product is then further processed to remove any remaining impurities, such as volatile organic compounds, using techniques such as distillation or crystallization.

The final step in the production process of 1,3,5-Tri(m-pyrid-3-ylphenyl)benzene is the packaging and distribution of the final product.
The product is typically packaged in drums or plastic containers, depending on the intended use, and is then shipped to the customer.
The customer may further process the product to meet their specific requirements, such as purification or formulation.

In conclusion, the production process of 1,3,5-Tri(m-pyrid-3-ylphenyl)benzene involves the preparation of the starting materials, the reaction process, and the purification of the final product.
The process is typically carried out in a well-ventilated area, using appropriate safety measures to ensure the safety of the workers and the environment.
The purified product is then further processed and packaged for distribution to the customer.
The production of 1,3,5-Tri(m-pyrid-3-ylphenyl)benzene is a complex process that requires careful attention to detail and the use of specialized equipment and techniques to ensure the highest quality product.
