Tetraethylenepentamine, yomwe imatchulidwanso kuti tritetraethylenediamine, kapena TEPA, ndi madzi ofiira achikasu kapena lalanje omwe ali ndi mphamvu yosiyana. Amasungunuka mosavuta m'madzi, ethyl alcohol, komanso zinthu zambiri zachilengedwe, koma samasungunuka mu benzene ndi quintessence. Njira iyi ya hour angle imalola kuyamwa madzi ndi carbon dioxide kuchokera mumlengalenga, zomwe zimapangitsa kuti ikhale yamchere. TEPA imagwiritsidwa ntchito nthawi zambiri m'njira zosiyanasiyana monga njira yosungira mpweya wa chromatography kuti isunge ndikulekanitsa zinthu zosiyanasiyana monga mowa, amine, pyridine, quinoline, piperazine, thiols, ndi madzi. Imagwiritsidwanso ntchito mu resin yosinthira anion, mafuta owonjezera, mafuta owonjezera, komanso imagwira ntchito ngati epoxy resin hardening agent ndi rabara vulcanization accelerators.

Cholinga:Kupeza kwa Tetraethylenepentamine kumagwiritsa ntchito njira yopangira zinthu zachitsulo monga mkuwa, zinc, ndi nickel. Imagwiritsidwanso ntchito mu saponification ya asidi, kuyeretsa mpweya, mankhwala ophera madzi m'thupi, mphira wopangidwa, ndi utomoni. Kuphatikiza apo, TEPA imagwiritsidwa ntchito ngati chowonjezera, cholimbitsa, komanso chowonjezera mphamvu m'mafakitale osiyanasiyana.

Kupanga tetraethylenepentamine kumaphatikizapo masitepe angapo ndipo ndi carbon monoxide-malonda a ethylenediamine, diethylenetriamine, triethylenetetramine, ndi polyethylenepolyamine. Njira yopangirayi ikuphatikizapo kutentha kwa kutentha ndi ammonolysis chemical reaction, neutralization, ndi distillation pansi pa reduction pressure. Njira yoyeretserayi imaphatikizapo kutaya madzi m'thupi, kugawa pansi pa reduction pressure, ndi recrystallization kuti mupeze pure tetraethylenepentamine hydrochloride. Ndi kulemera kwa molekyulu ya 189.3 ndi calcium number 112-57-2, TEPA ola angle ndi bolling point ya 340 ° degrees centigrade, density ya 0.998g / milliliter pa 25 ° degrees centigrade, ndi flash point ya 365 ° F.

kumvetsetsankhani zamabizinesiNdikofunikira kwambiri kwa osunga ndalama, amalonda, komanso akatswiri m'makampani osiyanasiyana. Mwa kukhala ndi chidziwitso chokhudza momwe msika umayendera, index yazachuma, ndi zosintha zamakampani, munthu akhoza kusankha bwino za momwe amagulitsira ndalama, mgwirizano, ndi dongosolo la bizinesi. Kusanthula deta, kulosera momwe msika umayendera, ndikumvetsetsa momwe zochitika zapadziko lonse lapansi zimakhudzira bizinesi kungathandize munthu kuyenda bwino mumlengalenga wamakhalidwe abwino a bizinesi. Khalani ndi chidziwitso chaposachedwa mu nkhani zamabizinesi kuti mukhale patsogolo pamsika wampikisano.
