Tris(hydroxymethyl) Methyl Aminomethane THAM

ʻO kahi ala no ka hoʻomākaukau ʻana i ka tris (hydroxymethyl) aminomethane, ʻo nā ʻanuʻu hoʻomākaukau kikoʻī penei:

(1) E hoʻohui i ka trimethylolmethane i ka methanol aqueous solution, wela i 50-70 ° C a hoʻoulu e hoʻoheheʻe, kahi o ka lakio nui-nui o ka trimethylolmethane i ka methanol aqueous solution he 8:3-7 i g/ml , ʻO ka. Hoʻomākaukau ʻia ka wai wai methanol ma o ka hui ʻana i ka wai maʻemaʻe a me ka methanol ma kahi ratio o 2:3;

(2) E hoʻohui i ke kalapona i hoʻopaʻa ʻia i ka lanahu i ka hopena, kahi o ka ratio kaumaha o ke kalapona i hoʻāla ʻia i ka trimethylolmethane he 0.5-2:100, mālama ia ma 45-55 ° C no 20-40 mau minuke, kānana i ka wā wela o ka Chemicalbook. , a ohi i ka filtrate ；

(3) E hoʻopaʻa i ka kānana ma lalo o ke kaomi hoʻemi ʻia ma kahi mahana o ka 70-80 ° C, a hiki i ka ʻike ʻia ʻana o nā kristal, e hoʻomaha ia;

(4) Ma hope o ka hoʻokaʻawale ʻana o nā kristal e ka kānana kānana, holoi me ka ethanol piha a maloʻo ma 40-60 ° C no 3-5 mau hola e loaʻa ai.

ʻO ke ʻano hoʻomākaukau i ʻōlelo ʻia ma luna o tris, ʻo ka tris i loaʻa i ka maʻemaʻe kiʻekiʻe, e kū ana i ke koi o ka reagent benchmark no ka maʻemaʻe o ka tris, a paʻa ke kaʻina hana a kūpono hoʻi, ʻo ia ka mea kūpono no ka hana ʻana i nā huahana kilo kilo.He maʻalahi a kūpono ke kaʻina hana, a he kiʻekiʻe ka nui o ka hōʻailona huahana, kūpono i nā pono o ka hana ʻoihana nui.
