Instantaneous feedback is crucial for several reasons: 1. Optimization of Reaction Conditions: By having real-time data, adjustments can be made promptly to maintain optimal conditions, improving reaction efficiency. 2. Safety Enhancements: Real-time monitoring can help detect any hazardous conditions early, reducing risks associated with high-pressure or high-temperature reactions. 3. Cost Reduction: By optimizing reactions in real-time, the amount of wasted materials and energy is minimized, leading to significant cost savings. 4. Product Quality: Ensuring that the reaction conditions are optimal at all times can lead to higher purity and yield of the desired product.
