Processing Method
Nzira yekugadzirira tris(hydroxymethyl)aminomethane, iwo chaiwo matanho ekugadzirira ndeaya anotevera:
(1) Wedzera trimethylolmethane kune methanol aqueous solution, kupisa kusvika 50-70 ° C uye fambisa kuti inyunguduke, umo huwandu hwehuwandu hwehuwandu hwe trimethylolmethane kune methanol aqueous solution ndeye 8: 3-7 mu g/ml, The methanol aqueous solution inogadzirwa nekusanganisa mvura yakachena uye methanol muhuwandu hwehuwandu hwe2: 3;
(2) Wedzera marasha activated kabhoni kune mhinduro, umo chiyero chehuremu chemarasha activated kabhoni kune trimethylolmethane iri 0.5-2: 100, chengeta pa45-55 ° C kwemaminitsi makumi maviri-40, sefa iyo Chemicalbook ichipisa. , uye unganidza iyo filtrate ;
(3) Simbisa iyo filtrate pasi pekudzvinyirira kwakaderedzwa pane tembiricha ye70-80 ° C, kusvikira makristasi achionekwa, rega itonhorere pasi;
(4) Mushure mokunge makristasi aparadzaniswa nekusveta filtration, shenesa neabsolute ethanol uye woma pa40-60 ° C kwemaawa 3-5 kuti uwane.
Iyo yakataurwa pamusoro nzira yekugadzirira yetris, iyo yakawanikwa tris ine kuchena kwakakwira, iyo inosangana nezvinodiwa zvebhenji reagent yekuchena kwetris, uye iyo nzira yakagadzikana uye inonzwisisika, iyo inonyanya kukodzera kugadzirwa kwe kilogram batch zvigadzirwa.Iyo nzira iri nyore uye inonzwisisika, uye chiyero chekufanirwa kwechigadzirwa chakakwira, icho chakakodzera kune zvinodiwa zvemaindasitiri makuru ekugadzira.
Chinangwa
Inonyanya kushandiswa mumishonga yepakati uye biochemical reagents.Pakati pefosfomycin, inoshandiswawo sevulcanization accelerator, cosmetics (kirimu, lotion), mineral oil, parafini emulsifier, biological buffer, biological buffer Agent.
Kuchengeta Nzira
Chengetedza muimba yekuchengetera inotonhorera, yakaoma uye ine mhepo yakanaka.Ramba kure nemoto nekupisa.
