Mild operating conditions are crucial for several reasons: 1. Energy Efficiency: Lower temperatures and pressures mean less energy consumption, which translates to reduced operational costs and a smaller carbon footprint. 2. Safety: Operating under milder conditions reduces the likelihood of dangerous reactions and explosions, enhancing the overall safety of the process. 3. Selectivity: Certain catalytic reactions are more selective under mild conditions, leading to higher yields of the desired product with fewer by-products. 4. Compatibility: Some substrates and products are sensitive to harsh conditions. Mild conditions ensure that these sensitive compounds are not degraded or altered.
