Sample interview questions: How do you evaluate and select appropriate catalyst loading for specific organic reactions?
Sample answer:
Catalyst Loading Evaluation and Selection
-
Reaction scale and efficiency: Determine the appropriate catalyst loading based on the reaction scale and desired efficiency. Smaller reactions may require lower catalyst loadings, while larger reactions may benefit from higher loadings.
-
Catalyst activity: Consider the intrinsic activity of the catalyst. More active catalysts require lower loadings to achieve the same reaction rate.
-
Substrate concentration: The catalyst loading should be proportional to the substrate concentration. Higher substrate concentrations require higher catalyst loadings to ensure sufficient catalytic turnover.
-
Reaction kinetics: Understand the reaction kinetics to determine the optimal catalyst loading for a given reaction rate. For first-order reactions, doubling the catalyst loading will double the reaction rate.
-
Catalyst cost and availability: Consider the cost and availability of the catalyst. Lower catalyst loadings can reduce costs, but also need to meet the reactivity requirements.
-
Ligand effects: If ligands are used in the reaction, their effects on catalyst activity a… Read full answer
