Habka habaynta
Habka diyaarinta tris (hydroxymethyl) aminomethane, tillaabooyinka diyaarinta gaarka ah waa sida soo socota:
(1) Ku dar trimethylolmethane xalka aqueous methanol, kuleyl ilaa 50-70 ° C oo walaaq si aad u milmaan, halkaas oo saamiga mugga trimethylolmethane ee xalka methanol aqueous waa 8: 3-7 g / ml, Xalka aqueous methanol waxaa lagu diyaariyaa isku dhafka biyo saafi ah iyo methanol ee saamiga mugga 2: 3;
(2) Ku dar kaarboonka firfircoon ee dhuxusha ee xalka, halkaas oo saamiga miisaanka dhuxusha kaarboonka firfircoon ee trimethylolmethane uu yahay 0.5-2:100, ku hay 45-55 ° C ilaa 20-40 daqiiqo, sifee inta uu kimikadu kulul yahay. , oo ururi shaandhada;
(3) Xooga saar shaandhaynta cadaadiska hoos u dhaca heerkulka fiirsashada ee 70-80 ° C, ilaa ay ka soo baxaan crystals, ha qaboojiso;
(4) Ka dib markii kirismaska ay kala soocaan sifeynta nuugista, ku raaci ethanol dhammaystiran oo ku qallaji 40-60 ° C 3-5 saacadood si aad u hesho.
Habka diyaarinta ee kor ku xusan ee tris, tris la helay ayaa leh nadiif sare, kaas oo buuxinaya shuruudaha reagent ee nadiifnimada tris, iyo geeddi-socodku waa mid deggan oo macquul ah, kaas oo si gaar ah ugu habboon wax soo saarka kiilogaraamyada bacaha.Nidaamku waa mid fudud oo macquul ah, iyo heerka shahaadooyinka alaabadu waa sarreeyaa, kaas oo ku habboon baahida wax soo saarka warshadaha ballaaran.
Ujeedo
Inta badan loo isticmaalo dhexdhexaadiyeyaasha dawooyinka iyo reagents biochemical.Dhexdhexaadiyaha fosfomycin, oo sidoo kale loo isticmaalo dardar-geliyaha vulcanization, waxyaabaha la isku qurxiyo (kareemka, lotion), saliidda macdanta, emulsifier paraffin, baayoloji, wakiilka kaydinta noolaha.
Habka Kaydinta
Ku kaydi bakhaar qabow, qalalan oo hawo fiican leh.Ka fogow dabka iyo ilaha kulaylka.
