The choice of raw materials can influence the selection of the catalyst in several ways: - Chemical Compatibility: The catalyst must be chemically compatible with the raw materials to avoid unwanted side reactions. - Reaction Conditions: Some raw materials require specific conditions (temperature, pressure) that only certain catalysts can withstand. - Environmental and Safety Concerns: Catalysts that minimize environmental impact and are safe to handle are preferred, especially when dealing with toxic or hazardous raw materials.
