Question

The article source and supplementary information compare p-toluenesulfonic acid and Amberlyst-15 as catalysts that can be used to synthesis Methyl Diantilis. In a paragraph please summarize and explain the differences between these two catalysts. This summary should include both differences of chemical principles and laboratory practicality.

Answer 1

Following are the solution to these questions:

Step-by-step explanation:

P-toluene sulfonic acid variations between Amberlyst-15

Acid p-Toluenesulfonic (PTSA)

• Organic acid Simple
• Aqua
• PTSA will be removed after a reaction from a difficult workflow
• Hard to recycle
• Environmental pollution conditions
• Composite single unit
• Toxic

Amberlyst 15

• Acid Polymer
• Solid
• Comfortably separated by simple filtration after the reaction.
• Easily recycle and reuse
• Not environmentally damaging
• ion exchange resin based on polystyrene.
• Nontoxic

P-toluene and Amberlyst-15 do have the same catalytic effect in the reaction as the mechanism is defined in the attached file. The Amberlyst 15 is always considered as best, given the better future for Amberlyst 15.
