I-Triethanolamine (2-[Bis-(2-hydroxy-ethyl)-amino]-ethano)

Imvelo yamakhemikhali

I-Triethanolamine iwuketshezi olunamafutha olungenambala olunephunga le-ammonia. Kulula ukumunca amanzi futhi luzophenduka umbala onsundu uma luvezwa emoyeni nasekukhanyeni. Uma izinga lokushisa liphansi, luzoba yikristalu eliphuzi eliphuzi elingenambala noma elikhanyayo. Luxubene namanzi, i-methanol kanye ne-acetone. Luncibilika kancane ku-benzene, i-ether, luncibilika kancane ku-carbon tetrachloride, i-n-heptane. Luhlobo lwe-alkaline enamandla, ehlanganiswe nama-proton, engasetshenziswa ekuphenduleni kokuqina.

Izicelo

Kumakhemikhali okuhlaziya, i-triethanolamine ingasetshenziswa njengesigaba esimile se-gas liquid chromatography (izinga lokushisa eliphakeme lingu-75 ℃ kanti i-solvent iyi-methanol ne-ethanol), esetshenziselwa ukuhlukaniswa kwe-pyridine kanye ne-methyl substitutes. Ku-complexometric titration kanye nokunye ukuhlaziya, ingasetshenziswa njenge-masking agent yama-ion aphazamisayo. Isibonelo, kusisombululo se-pH = 10, lapho sisebenzisa i-EDTA ye-titration ye-magnesium, i-zinc, i-cadmium, i-calcium, i-nickel kanye namanye ama-ion, i-reagent ingasetshenziswa ekufihleni i-titanium, i-aluminium, i-iron, i-tin kanye namanye ama-ion. Ngaphezu kwalokho, ingabizwa nangokuthi i-hydrochloric acid ibe yisisombululo se-buffer senani elithile le-pH.

I-Triethanolamine isetshenziswa kakhulu ekwenziweni kwama-surfactants, ama-detergents aketshezi, izimonyo njalo njalo. Ingenye yezingxenye zokusika uketshezi kanye noketshezi oluvimbela ukuqandisa. Ngesikhathi sokwenziwa kwe-polymerization yerabha ye-nitrile, ingasetshenziswa njengesiqalisi, njenge-activator ye-vulcanization yerabha yemvelo kanye nerabha yokwenziwa. Ingasetshenziswa futhi njenge-emulsifiers yamafutha, i-wax kanye nezibulala-zinambuzane, i-moisturizer kanye ne-stabilizer yezimonyo, izithambisi zendwangu kanye nezithasiselo zokulwa nokugqwala kwezithambisi. I-Triethanolamine iyakwazi futhi ukumunca i-carbon dioxide kanye ne-hydrogen sulfide kanye namanye amagesi. Ngesikhathi sokuhlanza igesi ye-coke oven kanye namanye amagesi ezimboni, ingasetshenziswa ukususa amagesi e-acid. Iphinde ibe yi-ejenti yokufihla esetshenziswa kakhulu ekuhlolweni kwe-EDTA titration.

Ifomu elibonakalayo

uketshezi oluphuzi olungenambala/oluphuzi ngokukhanyayo

Isikhathi sokuphelelwa yisikhathi

Ngokusho kokuhlangenwe nakho kwethu, umkhiqizo ungagcinwa izinsuku ezingu-12.izinyanga kusukela osukwini lokulethwa uma zigcinwe ezitsheni ezivalwe kahle, zivikelwe ekukhanyeni nasekushiseni futhi zigcinwe emazingeni okushisa aphakathi kuka-5 -30°C.
