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

Imiterere y'ibinyabutabire

Triethanolamine ni amazi adafite ibara kandi afite impumuro ya ammonia. Yoroshye kwinjiza amazi kandi azahinduka ibara ry'umukara iyo ashyizwe mu kirere n'urumuri. Iyo ubushyuhe buri hasi, azahinduka kristu y'umuhondo cyangwa iy'umuhondo wijimye. Ashobora kuvangwa n'amazi, methanol na acetone. Ashongeshwa muri benzene, ether, ashongeshwa gato muri tetrachloride ya karuboni, n-heptane. Ni ubwoko bwa alkaline ikomeye, ivanze na proton, ishobora gukoreshwa mu gukora ihinduka ry'umukungugu.

Porogaramu

Mu buhanga bwo gusesengura, triethanolamine ishobora gukoreshwa nk'igice cyo guhagarara cya chromatography y'amazi ya gaze (ubushyuhe ntarengwa ni 75 ℃ aho solvent ari methanol na ethanol), ikoreshwa mu gutandukanya pyridine na methyl substituts. Mu buryo bwa complexometric titration n'ubundi buryo bwo gusesengura, ishobora gukoreshwa nk'ikintu gikingira iyoni. Urugero, mu gisubizo cya pH = 10, iyo dukoresheje EDTA mu gisubizo cya manyeziyumu, zinc, cadmium, calcium, nickel n'izindi iyoni, reagent ishobora gukoreshwa mu gupfuka titanium, aluminium, icyuma, tin n'izindi iyoni. Byongeye kandi, ishobora kandi kwitwa aside hydrochloric mu gisubizo cy'ubufasha gifite agaciro runaka ka pH.

Triethanolamine ikoreshwa cyane cyane mu gukora ibintu bigabanya ubushyuhe, isabune y'amazi, amavuta yo kwisiga n'ibindi. Ni kimwe mu bigize gukata amazi n'amazi arwanya ubukonje. Mu gihe cyo gukoresha polymerization ya nitrile rubber, ishobora gukoreshwa nk'ikintu gitera imbaraga, ikaba ikintu gitera imbaraga vulcanization ya rubber karemano na rubber ya sintetike. Ishobora kandi gukoreshwa nk'ibintu bitera imbaraga amavuta, ishashi n'imiti yica udukoko, itera imbaraga n'imiti irinda ubushyuhe, ifasha mu gutunganya imyenda ndetse n'ibindi bikoresho birwanya ingese. Triethanolamine kandi ishobora kwinjiza dioxyde de carbone na hydrogen sulfide n'indi myuka. Mu gihe cyo gusukura gaze ya coke furne n'indi myuka yo mu nganda, ishobora gukoreshwa mu gukuraho gaze ya aside. Ni kandi ikintu gikoreshwa cyane mu gupfuka mu isuzuma rya EDTA.

Igihe cyo kubika

Dukurikije ubunararibonye bwacu, ibicuruzwa bishobora kubikwa mu gihe cy'iminsi 12amezi uhereye igihe cyo gutanga iyo bibitswe mu bikoresho bifunze neza, birinzwe urumuri n'ubushyuhe kandi bikabikwa ku bushyuhe buri hagati ya 5 -30°C.
