Mokhoa oa ho sebetsa

Mokhoa oa ho lokisa tris(hydroxymethyl)aminomethane, mehato e khethehileng ea ho itokisa ke e latelang:

(1) Eketsa trimethylolmethane ho tharollo ea metsi a methanol, mocheso ho 50-70 ° C 'me u hlohlelletse ho qhibiliha, moo tekanyo ea boima ba trimethylolmethane ho tharollo ea metsi a methanol e leng 8: 3-7 ka g/ml. tharollo ea metsi a methanol e lokiselitsoe ka ho kopanya metsi a hloekileng le methanol ka tekanyo ea boholo ba 2: 3;

(2) Eketsa carbon activated carbon ho tharollo, moo tekanyo ea boima ba carbon activated carbon ho trimethylolmethane e leng 0.5-2: 100, e boloke ho 45-55 ° C bakeng sa metsotso ea 20-40, e sefa ha Chemicalbook e chesa. , le ho bokella filtrate;

(3) Tsepamisa maikutlo ho filtrate tlas'a khatello e fokotsehileng mocheso oa mahloriso oa 70-80 ° C, ho fihlela likristale li hlaha, li lumelle hore li pholile;

(4) Ka mor'a hore likristale li arohane ka ho suction filtration, hlatsoa ka ethanol e feletseng 'me u omelle ka 40-60 ° C bakeng sa lihora tse 3-5 ho fumana.

Mokhoa o boletsoeng ka holimo oa ho itokisa oa tris, tris e fumanoeng e na le bohloeki bo phahameng, e finyellang tlhokahalo ea reagent ea benchmark bakeng sa bohloeki ba tris, 'me ts'ebetso e tsitsitse ebile e utloahala, e loketseng ka ho khetheha bakeng sa tlhahiso ea lihlahisoa tsa batch ea lik'hilograma.Ts'ebetso e bonolo ebile e utloahala, 'me sekhahla sa ho tšoaneleha ha sehlahisoa se phahame, se loketseng litlhoko tsa tlhahiso e kholo ea indasteri.
