I-Cephalosporin, esetyenziswa njengendawo ephakathi ye-cefbutan kunye ne-cefazoxime.
I-asidi ye-sulfuric egxininisiweyo (104.3mL, 1.92mol) yongezwa kwiibhotile ezintathu, emva koko isophthalic acid (40g, 0.24mol) yongezwa, ixutywe kwaye ishushu kwi-60 ℃, ibanjwe i-0.5h, kunye ne-60% ye-nitric acid (37.8g, 0.36) mol) yongezwa ukulawula iqondo lokukhawulezisa amathontsi.Yongeza kwiiyure ze-2.Emva koko, ukusabela kokugcina ubushushu kwi-60 ℃ kwiiyure ezi-2.Phola ukuya ngaphantsi kwe 50 ° C, emva koko wongeze i-100mL yamanzi.Izinto eziphathekayo zipholile kwiqondo lokushisa, zithululelwe kwisihlunu, zixutywe ukuze zisuse i-asidi yenkunkuma, ikhekhe lokucoca lihlanjwe ngamanzi, lihlanjululwe ukuze lihlaziye, kwaye imveliso emhlophe yayiyi-34.6 grams, isivuno sasiyi-68.4%.
I-20Kg okanye i-25Kg / ibhakethi, ibhakethi yekhadibhodi, efakwe umaleko omhlophe kunye nengxowa emnyama ye-polyethylene.I-2℃-8℃ eyomileyo, indawo epholileyo, kude nendawo yokugcina ukukhanya, isebenza iminyaka emi-2.
