Ọna kan fun igbaradi tris (hydroxymethyl) aminomethane, awọn igbesẹ igbaradi pato jẹ bi atẹle:

(1). Ojutu olomi kẹmika ti pese sile nipasẹ didapọ omi mimọ ati kẹmika kẹmika ni ipin iwọn didun ti 2: 3;

(2) Fi erogba ti a mu ṣiṣẹ eedu si ojutu, ninu eyiti ipin iwuwo ti erogba ti a mu ṣiṣẹ si trimethylolmethane jẹ 0.5-2: 100, tọju rẹ ni 45-55 ° C fun awọn iṣẹju 20-40, ṣe àlẹmọ lakoko ti Kemikali gbona. , ati ki o gba awọn filtrate;

(3) Fi oju si filtrate labẹ titẹ ti o dinku ni iwọn otutu ti 70-80 ° C, titi awọn kirisita yoo fi han, jẹ ki o tutu;

(4) Lẹhin ti awọn kirisita ti yapa nipasẹ sisẹ afamora, fi omi ṣan pẹlu ethanol pipe ati ki o gbẹ ni 40-60 ° C fun awọn wakati 3-5 lati gba.

Ọna igbaradi ti a mẹnuba loke ti tris, tris ti o gba ni mimọ ti o ga, eyiti o pade ibeere ti reagent ala fun mimọ ti tris, ati pe ilana naa jẹ iduroṣinṣin ati ironu, eyiti o dara julọ fun iṣelọpọ awọn ọja ipele kilogram.Ilana naa rọrun ati oye, ati pe oṣuwọn iyege ọja jẹ giga, eyiti o dara fun awọn iwulo iṣelọpọ ile-iṣẹ nla.
