Cephalosporin, i whakamahia hei takawaenga mo Cefbutan me Cefazoxime.
Ko te waikawa sulfuric uaua (104.3ml, 1.92mol) i honoa ki te waikawa (40g, 0.24mol te 60%, 0.36mol) te mana o te tohu whakaterenga. Tāpiri i roto i te 2 haora. I muri i te taapiri, te tauhohenga wera i te 60 ℃ mo te 2 haora. Kia pai ki raro iho i te 50 ° C, ka tapirihia te 100ml wai. I whakamataoatia te rauemi ki te pāmahana o te rūma, ka ringihia ki te tango i te waikawa paru, ka horoia te keke ki te wai, ko te hua ma te 6,6% te hua.
20kg ranei 25kg ranei, peere, peere kaata, kua kapi ki te apa ma me te putea polyethylene pango. 2 ℃ -8 ℃ Te waahi maroke, te wahi raumati, i tawhiti atu i te rokiroki maama, he tika mo te 2 tau.
