The response surface diagrams of the interaction between the four factors from Catalytic synthesis of N-butyl carboxylate with immobilized ionic liquid based on response surface methodology optimization

Interactions exist among reaction time (A), molar ratio of acid to alcohol (B), reaction temperature (C) and catalyst dosage (D). Response surface analysis of the interaction between the four factors was performed, and response surface diagrams were drawn as shown in Figure S1 - Figure S6
