Indlela Yokucubungula
Indlela yokulungiselela i-tris(hydroxymethyl)aminomethane, izinyathelo ezithile zokulungiselela zimi kanje:
(1) Engeza i-trimethylolmethane kusisombululo samanzi se-methanol, ukushisa ku-50-70 ° C futhi ugovuze ukuze incibilike, lapho isilinganiso somthamo wevolumu ye-trimethylolmethane kusixazululo samanzi se-methanol singu-8:3-7 ku-g/ml, Isixazululo se-methanol se-aqueous silungiswa ngokuxuba amanzi ahlanzekile ne-methanol ngesilinganiso somthamo we-2: 3;
(2) Faka i-carbon activated carbon esixazululweni, lapho isilinganiso sesisindo sekhabhoni ecushiwe yamalahle ku-trimethylolmethane singu-0.5-2:100, sigcine ku-45-55°C imizuzu engu-20-40, sihlunge ngenkathi i-Chemicalbook ishisa. , bese uqoqa isihlungi ;
(3) Gxilisa i-filtrate ngaphansi kwengcindezi encishisiwe ekushiseni okuhlushwa kwe-70-80 ° C, kuze kube yilapho kuvela amakristalu, ake apholile;
(4) Ngemva kokuba amakristalu ehlukaniswe ngokuhlunga, hlambulula nge-ethanol ephelele futhi wome ku-40-60 ° C amahora angu-3-5 ukuze uthole.
Indlela yokulungiselela eshiwo ngenhla ye-tris, i-tris etholiwe inokuhlanzeka okuphezulu, okuhlangabezana nemfuneko ye-reagent yokuma yokuhlanzeka kwe-tris, futhi inqubo izinzile futhi inengqondo, efaneleka ngokukhethekile ukukhiqizwa kwemikhiqizo ye-kilogram ye-batch.Inqubo ilula futhi inengqondo, futhi izinga lokufaneleka komkhiqizo liphezulu, elifanele izidingo zokukhiqizwa kwezimboni ezinkulu.
Inhloso
Isetshenziswa kakhulu kuma-intermediate emithi kanye nama-reagents we-biochemical.Emaphakathi ye-fosfomycin, ebuye isetshenziswe njenge-vulcanization accelerator, izimonyo (ukhilimu, amafutha okugcoba), amafutha amaminerali, i-emulsifier kapharafini, i-biological buffer, i-biological buffer Agent.
Indlela Yesitoreji
Gcina endaweni epholile, eyomile futhi enomoya omuhle.Gcina kude nomlilo nemithombo yokushisa.
