AI Technical Summary
Existing methods for synthesizing amoxicillin suffer from problems such as high raw material consumption, severe equipment corrosion, difficulties in environmental protection, unstable product yield, and high production costs.
Zirconium-containing biochar material was prepared using straw as raw material and mixed with ammonium phosphomolybdate as a solid acid catalyst for the catalytic synthesis of D-p-hydroxyphenylglycine methyl ester. Subsequently, it was enzymatically synthesized with 6-APA to synthesize amoxicillin, avoiding the use of hazardous chemicals and simplifying the production process.
It improves the catalytic performance and lifespan of the catalyst, reduces production costs, simplifies the process, enhances safety, reduces energy and equipment consumption, and increases the yield and purity of amoxicillin.
