Txoj kev ua
Ib txoj hauv kev npaj tris (hydroxymethyl) aminomethane, cov txheej txheem tshwj xeeb yog raws li hauv qab no:
(1) Ntxiv cov trimethylolmethane rau hauv cov tshuaj methanol aqueous, kub rau 50-70 ° C thiab do kom yaj, nyob rau hauv qhov sib piv loj ntawm trimethylolmethane rau cov tshuaj methanol aqueous yog 8: 3-7 hauv g / ml, methanol aqueous tov yog npaj los ntawm kev sib xyaw cov dej ntshiab thiab methanol hauv qhov sib piv ntawm 2: 3;
(2) Ntxiv charcoal activated carbon rau cov tshuaj, nyob rau hauv qhov hnyav piv ntawm charcoal activated carbon rau trimethylolmethane yog 0.5-2: 100, khaws cia ntawm 45-55 ° C rau 20-40 feeb, lim nws thaum lub Chemicalbook kub. , thiab sau cov filtrate;
(3) Ua kom pom tseeb hauv qhov txo qis ntawm qhov kub thiab txias ntawm 70-80 ° C, kom txog thaum cov muaju tshwm sim, cia nws txias;
(4) Tom qab cov crystals sib cais los ntawm kev nqus pom, yaug nrog ethanol kiag li thiab qhuav ntawm 40-60 ° C rau 3-5 teev kom tau txais.
Txoj kev npaj tau hais los saum toj no ntawm tris, qhov tau txais tris muaj siab purity, uas ua tau raws li qhov yuav tsum tau ua ntawm cov qauv ntsuas reagent rau purity ntawm tris, thiab cov txheej txheem yog ruaj khov thiab tsim nyog, uas yog tshwj xeeb tshaj yog haum rau zus tau tej cov kilogram batch khoom.Cov txheej txheem yog yooj yim thiab tsim nyog, thiab cov khoom tsim nyog tus nqi yog siab, uas yog haum rau cov kev xav tau ntawm loj-scale industrial ntau lawm.
Lub hom phiaj
Feem ntau siv nyob rau hauv kws tshuaj intermediates thiab biochemical reagents.Intermediate ntawm fosfomycin, kuj tseem siv los ua vulcanization accelerator, tshuaj pleev ib ce (cream, lotion), ntxhia roj, paraffin emulsifier, lom tsis zoo, tshuaj lom neeg tsis zoo.
Txoj kev khaws cia
Khaws rau hauv qhov chaw txias, qhuav thiab zoo-ventilated warehouse.Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
