Processing Njira

Njira yokonzekera tris(hydroxymethyl) aminomethane, njira zokonzekera ndi izi:

(1) Onjezani trimethylolmethane ku methanol amadzimadzi njira, kutentha kwa 50-70 ° C ndi kusonkhezera kupasuka, mmene misa-volume chiŵerengero cha trimethylolmethane kwa methanol amadzimadzi njira ndi 8:3-7 mu g/ml , The Methanol amadzimadzi njira anakonza ndi kusakaniza madzi oyera ndi methanol mu voliyumu chiŵerengero cha 2: 3;

(2) Onjezani makala opangidwa ndi kaboni ku yankho, momwe chiŵerengero cha kulemera kwa makala opangidwa ndi kaboni ku trimethylolmethane ndi 0.5-2: 100, sungani pa 45-55 ° C kwa mphindi 20-40, sefani pamene Chemicalbook ikutentha. , ndi kutolera zosefera;

(3) Yang'anani fyulutayo pansi pa kupanikizika kochepa pa kutentha kwapakati pa 70-80 ° C, mpaka makhiristo awonekere, alole kuti azizizira;

(4) Pambuyo pa makhiristo atasiyanitsidwa ndi kusefera kwa kuyamwa, yambani ndi ethanol mtheradi ndikuwuma pa 40-60 ° C kwa maola 3-5 kuti mupeze.

Njira yokonzekera yomwe tatchulayi ya tris, tris yomwe imapezeka imakhala ndi chiyero chachikulu, chomwe chimakwaniritsa zofunikira za benchmark reagent ya chiyero cha tris, ndipo ndondomekoyi ndi yokhazikika komanso yololera, yomwe ili yoyenera kwambiri popanga katundu wa kilogalamu.Njirayi ndi yophweka komanso yololera, ndipo chiwerengero cha kuyenerera kwa mankhwala ndipamwamba, chomwe chili choyenera pa zosowa za mafakitale akuluakulu.
