Tetraethylenepentamine, tseem hu ua tritetraethylenediamine, lossis TEPA, yog cov kua dej daj lossis txiv kab ntxwv-liab uas muaj ntau yam ntxwv. Nws yooj yim yaj hauv dej, ethyl cawv, thiab feem ntau cov kuab tshuaj organic, tab sis tsis yaj hauv benzene thiab quintessence. Cov tshuaj no muaj peev xwm nqus dej thiab carbon dioxide los ntawm huab cua, ua rau nws alkaline hauv xwm. TEPA feem ntau siv rau hauv ntau yam kev siv xws li roj chromatography stationary solution rau kev khaws cia thiab sib cais ntawm ntau yam tshuaj xws li cawv, amine, pyridine, quinoline, piperazine, thiols, thiab dej. Nws kuj siv rau hauv anion exchange resin, roj nplua nyeem additive, roj roj additive, thiab ua haujlwm ua epoxy resin hardening agent thiab roj hmab vulcanization accelerators.

Lub Hom Phiaj:Tetraethylenepentamine nrhiav pom nws siv rau hauv kev titration nyuaj ntawm cov khoom siv hlau xws li tooj liab, zinc, thiab nickel siv txoj kev xaus tam sim no. Nws kuj tseem siv rau hauv saponification ntawm cov tshuaj acidic, roj purification, dehydration agent, synthetic roj hmab, thiab resin daim ntawv thov. Tsis tas li ntawd, TEPA yog siv ua additive, hardening agent, thiab accelerator hauv ntau yam lag luam.

Kev tsim cov tetraethylenepentamine muaj ntau theem thiab yog cov pa roj carbon monoxide-khoom lag luam ntawm ethylenediamine, diethylenetriamine, triethylenetetramine, thiab polyethylenepolyamine. Cov txheej txheem tsim khoom suav nrog thermal amination thiab ammonolysis tshuaj lom neeg tshuaj lom neeg, neutralization, thiab distillation nyob rau hauv txo qhov siab. Cov txheej txheem refining suav nrog dehydration, fractionation nyob rau hauv txo qhov siab, thiab recrystallization rau tau txais ntshiab tetraethylenepentamine hydrochloride. Nrog rau qhov hnyav molecular ntawm 189.3 thiab calcium tus lej 112-57-2, TEPA teev lub kaum sab xis ntawm 340 ° degree centigrade, qhov ceev ntawm 0.998g / milliliter ntawm 25 ° degree centigrade, thiab qhov flash point ntawm 365 ° F.

kev nkag siabxov xwm lag luamyog qhov tseem ceeb rau cov tub ua lag luam, cov neeg ua lag luam, thiab cov kws tshaj lij hauv ntau yam kev lag luam. Los ntawm kev paub txog kev lag luam, kev lag luam, thiab kev hloov tshiab ntawm lub tuam txhab, tus neeg tuaj yeem txiav txim siab zoo txog kev nqis peev, kev koom tes, thiab kev lag luam. tshuaj xyuas cov ntaub ntawv, kwv yees kev hloov pauv ntawm kev lag luam, thiab nkag siab txog qhov cuam tshuam ntawm cov xwm txheej thoob ntiaj teb rau kev lag luam tuaj yeem pab tus neeg taug kev mus rau lub zog ntawm lub ntiaj teb kev lag luam zoo. paub txog kev hloov tshiab tshiab hauv xov xwm lag luam kom nyob ua ntej hauv kev sib tw ua lag luam.
