Tetraethylenepentamine, tseem hu ua tritetraethylenediamine, abbreviated li TEPA, yog ib tug daj los yog txiv kab ntxwv-liab viscous kua. Yooj yim soluble hauv dej, ethanol thiab feem ntau cov organic solvents, insoluble nyob rau hauv benzene thiab ether.Nws yooj yim absorbs dej thiab carbon dioxide nyob rau hauv cov huab cua. Alkaline. Nws yog tau los ntawm thermal amination thiab ammonolysis cov tshuaj tiv thaiv ntawm dichloroethane thiab ammonia, neutralizing nrog alkali thiab tom qab ntawd distilling nyob rau hauv lub siab txo. Siv los ua cov roj chromatography nyob ruaj ruaj rau kev xaiv khaws cia thiab Cov Tshuaj Siv Tshuaj cais cov cawv, amines, pyridine, quinoline, piperazine, thiols thiab dej. Siv nyob rau hauv anion pauv resins, lubricating roj additives, roj roj additives, thiab kuj siv raws li epoxy resin curing agents, roj hmab vulcanization accelerators, thiab lwm yam.

Lub hom phiaj

: Tetraethylene pentamine tuaj yeem siv rau kev sib tw ntawm tooj liab, zinc thiab npib tsib xee los ntawm txoj kev xaus tam sim no, saponification ntawm acidic tshuaj, hluavtaws roj hmab thiab resin gas purification thiab dehydration agent. Kuj tseem siv los ua additives, curing agents, accelerators, thiab lwm yam.

Txoj kev tsim khoom:

Cov khoom no yog cov khoom sib xyaw ntawm ethylenediamine, diethylenetriamine, triethylenetetramine, thiab polyethylenepolyamine. Rau cov qauv tsim thiab kev ua haujlwm, thov xa mus rau ethylenediamine. Txawm li cas los xij, qhov kub ntawm cov tshuaj ammonolysis yuav tsum yog 160 txog 250 ° C, thiab lub siab yuav tsum siab tshaj 4.0MPa. Distilled cov khoom nyoos polyamine nyob rau hauv lub siab txo, sau cov feem ntawm 160-210 ° C nyob rau hauv ib tug siab ntawm 1.3kPa, thiab tau cov tiav cov khoom Chemicalbook ntawm tetraethylpentamine tom qab txias. Refining txoj kev: Dehydrate nrog hlau sodium los yog anhydrous calcium sulfate thiab ces fractionate nyob rau hauv txo siab. Koj tuaj yeem yaj 150g ntawm tetraethylenepentamine hauv 300mL ntawm 95% ethanol, thiab maj mam poob hauv 180mL ntawm cov concentrated hydrochloric acid thaum txias, ua kom kub hauv qab 20 ° C. Lim tawm cov dawb precipitate, recrystallize nws peb zaug nrog ib tug sib tov ntawm ethanol thiab dej, ntxuav nrog ether, thiab qhuav nyob rau hauv lub nqus tsev vacuum kom tau cov ntshiab tetraethylenepentamine hydrochloride.
