| titleOfInvention | A kind of catalyst for synthesizing cefoxitin |
| abstract | The invention discloses a catalyst for synthesizing cefoxitin. The carrier of the catalyst is magnesium aluminum hydrotalcite, and the composition of active components is Ca 1.0 P a O (2*1+5*a)/2 , wherein Ca is calcium element, P is phosphorus element, O is oxygen element. The present invention uses magnesium-aluminum hydrotalcite as a carrier, and uses excess impregnation method to load active components to prepare a catalyst, the method is simple, the conditions are controllable, the obtained catalyst is moderately alkaline, the reaction is mild, and the ring-opening of the cephalosporin product due to excessive alkalinity is avoided. Side reactions occur. In addition, the catalyst can simultaneously perform hydrolysis and carbamylation, thereby simplifying the production process and reducing the production cost. |
