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

Uhlobo lwekhemikhali

I-Triethanolamine lulwelo olunamafutha olungenambala olunevumba le-ammonia. Kulula ukufunxa amanzi kwaye luya kuba mdaka xa luvezwa emoyeni nasekukhanyeni. Xa kushushu, luya kuba yikristale ye-cubic engenambala okanye etyheli ekhanyayo. Ixutywa namanzi, i-methanol kunye ne-acetone. Iyanyibilika kwi-benzene, i-ether, iyanyibilika kancinci kwi-carbon tetrachloride, i-n-heptane. Luhlobo lwe-alkaline enamandla, edityaniswe neeprotons, kwaye ingasetyenziselwa ukusabela kwe-condensation.

Izicelo

Kwikhemistri yohlalutyo, i-triethanolamine ingasetyenziswa njengesigaba esisisigxina se-gas liquid chromatography (ubushushu obuphezulu yi-75 ℃ apho i-solvent iyi-methanol kunye ne-ethanol), isetyenziselwa ukwahlula i-pyridine kunye ne-methyl substitutes. Kwi-complexometric titration kunye nolunye uhlalutyo, ingasetyenziswa njenge-masking agent yee-ion eziphazamisayo. Umzekelo, kwisisombululo se-pH = 10, xa sisebenzisa i-EDTA kwi-titration ye-magnesium, i-zinc, i-cadmium, i-calcium, i-nickel kunye nezinye ii-ion, i-reagent ingasetyenziselwa ukufihla i-titanium, i-aluminium, i-iron, i-tin kunye nezinye ii-ion. Ukongeza, inokuthiwa yi-hydrochloric acid ibe yisisombululo se-buffer sexabiso elithile le-pH.

I-Triethanolamine isetyenziswa kakhulu ekwenziweni kwezinto ezibangela ukurhawuzelelwa, izicoci zolwelo, izinto zokuthambisa njl. Lelinye lamacandelo okusika ulwelo kunye nolwelo olulwa nokuqandisa. Ngexesha le-polymerization yerabha ye-nitrile, ingasetyenziswa njenge-activator, njenge-activator ye-vulcanization yerabha yendalo kunye nerabha yokwenziwa. Ingasetyenziswa njenge-emulsifiers yeoyile, i-wax kunye nezibulala-zinambuzane, i-moisturizer kunye ne-stabilizer yezinto zokuthambisa, izithambisi zelaphu kunye nezongezo ze-anti-corrosion zezinto zokuthambisa. I-Triethanolamine ikwakwazi ukufunxa i-carbon dioxide kunye ne-hydrogen sulfide kunye nezinye iigesi. Ngexesha lokucoca igesi ye-coke oven kunye nezinye iigesi zoshishino, ingasetyenziselwa ukususa iigesi ze-asidi. Ikwayi-arhente yokufihla esetyenziswa rhoqo kwi-EDTA titration assay.

Imo ebonakalayo
