Indlela yokuqhuba
Indlela yokulungiselela i-tris(hydroxymethyl)aminomethane, amanyathelo akhethekileyo okulungiselela alandelayo:
(1) Yongeza i-trimethylolmethane kwisisombululo samanzi se-methanol, ukushisa kwi-50-70 ° C kwaye ugxobhoze ukunyibilika, apho umlinganiselo womthamo we-trimethylolmethane kwisisombululo samanzi se-methanol ngu-8: 3-7 kwi-g / ml, isisombululo se-methanol se-aqueous silungiswa ngokuxuba amanzi acocekileyo kunye ne-methanol kwi-volume ratio ye-2: 3;
(2) Yongeza i-charcoal activated carbon kwisisombululo, apho umlinganiselo we-charcoal activated carbon kwi-trimethylolmethane yi-0.5-2: 100, yigcine kwi-45-55 ° C imizuzu engama-20-40, ihluze ngelixa i-Chemicalbook ishushu. , kwaye uqokelele isihluzi;
3
(4) Emva kokuba iikristale zihlulwe ngokuhluzwa kwe-suction, hlambulula nge-ethanol epheleleyo kwaye uyomise kwi-40-60 ° C kwiiyure ezingama-3-5 ukufumana.
Indlela yokulungiselela ekhankanywe ngasentla ye-tris, i-tris efunyenweyo inobunyulu obuphezulu, ehlangabezana nemfuneko ye-reagent ye-benchmark yokuhlanjululwa kwe-tris, kwaye inkqubo izinzile kwaye ingqiqo, eyona nto ifanelekileyo ukuveliswa kweemveliso zebhetshi yeekhilogram.Inkqubo ilula kwaye inengqiqo, kwaye izinga lokufaneleka kwemveliso liphezulu, elilungele iimfuno zemveliso yemveliso enkulu.
Injongo
Isetyenziswa kakhulu kwi-pharmaceutical intermediates kunye ne-biochemical reagents.Umbindi wefosfomycin, ekwasetyenziswa njenge vulcanization accelerator, izinto zokuthambisa (cream, lotion), imineral oil, parafini emulsifier, biological buffer, biological buffer Agent.
Indlela yokugcina
Gcina kwindawo epholileyo, eyomileyo kwaye engenamoya.Zigcine kude nomlilo kunye nemithombo yobushushu.
