Tetraethylenepentamine, tseem hu ua tritetraethylenediamine, luv ua TEPA, yog cov kua daj lossis txiv kab ntxwv-liab viscous. Yooj yim yaj hauv dej, ethanol thiab feem ntau cov organic solvents, insoluble hauv benzene thiab ether. Nws yooj yim nqus dej thiab carbon dioxide hauv huab cua. Alkaline. Nws tau txais los ntawm thermal amination thiab ammonolysis reaction ntawm dichloroethane thiab ammonia, neutralizing nrog alkali thiab tom qab ntawd distillation nyob rau hauv txo qhov siab. Siv ua roj chromatography stationary solution rau kev khaws cia xaiv thiab Chemicalbook sib cais ntawm cawv, amines, pyridine, quinoline, piperazine, thiols thiab dej. Siv rau hauv anion pauv resins, lubricating roj additives, roj roj additives, thiab kuj siv ua epoxy resin curing agents, roj hmab vulcanization accelerators, thiab lwm yam.

Lub Hom Phiaj

Tetraethylene pentamine siv tau rau kev titration ntawm tooj liab, zinc thiab nickel los ntawm txoj kev xaus tam sim no, saponification ntawm cov kua qaub, roj hmab hluavtaws thiab cov roj hmab roj hmab purification thiab dehydration agent. Kuj siv tau ua cov additives, curing agents, accelerators, thiab lwm yam.

Txoj kev tsim khoom:

Cov khoom no yog cov khoom sib koom ua ke ntawm ethylenediamine, diethylenetriamine, triethylenetetramine, thiab polyethylenepolyamine. Rau cov ntsiab cai tsim khoom thiab kev ua haujlwm, thov saib ethylenediamine. Txawm li cas los xij, qhov kub ntawm cov tshuaj ammonolysis yuav tsum yog 160 txog 250 ° C, thiab qhov siab yuav tsum siab dua 4.0MPa. Distill cov khoom polyamine nyoos hauv qab qhov siab txo qis, sau cov feem ntawm 160-210 ° C hauv qab qhov siab ntawm 1.3kPa, thiab tau txais cov khoom tiav Chemicalbook ntawm tetraethylpentamine tom qab txias. Txoj kev ua kom zoo: Dehydrate nrog cov hlau sodium lossis anhydrous calcium sulfate thiab tom qab ntawd fractionate hauv qab qhov siab txo qis. Koj tuaj yeem yaj 150g ntawm tetraethylenepentamine hauv 300mL ntawm 95% ethanol, thiab maj mam poob rau hauv 180mL ntawm concentrated hydrochloric acid thaum txias, khaws qhov kub hauv qab 20 ° C. Lim cov av dawb tawm, rov ua dua peb zaug nrog cov ethanol thiab dej sib xyaw, ntxuav nrog ether, thiab ziab hauv qab lub tshuab nqus tsev kom tau txais tetraethylenepentamine hydrochloride ntshiab.
