Kusanthula Mwatsatanetsatane kwa Boiling Point ya Triethylamine
Triethylamine (TEA mwachidule) ndi mankhwala wamba omwe ali m'gulu la amine la mankhwala. Amagwiritsidwa ntchito kwambiri m'mafakitale ambiri monga mankhwala, mankhwala ophera tizilombo, utoto, zosungunulira ndi zina zotero. Monga mankhwala omwe amagwiritsidwa ntchito nthawi zambiri, zinthu zakuthupi za Triethylamine, makamaka kuwira kwake, ndizozigawo zomwe ziyenera kumveka bwino ndikuwongolera muzinthu zambiri zamakina. Mu pepala ili, tikambirana za kuwira kwa triethylamine mwatsatanetsatane, kusanthula zifukwa za physicochemical kumbuyo kwake, ndi kufunikira kwake pakugwiritsa ntchito.
Chidule cha kuwira kwa triethylamine
Kuwira kwa triethylamine ndi 89.5 ° C (193.1 ° F), komwe ndi kutentha kwake kowira pamtunda wokhazikika wa mumlengalenga (1 atm). Malo otentha ndi kutentha komwe mpweya wamadzimadzi umakhala wofanana ndi kuthamanga kwa kunja, kutanthauza kuti pa kutentha uku triethylamine amasintha kuchoka ku madzi kupita ku gaseous state. Kuwira ndi chinthu chofunikira kwambiri chakuthupi ndipo ndikofunikira kuti timvetsetse momwe triethylamine imagwirira ntchito munthawi zosiyanasiyana.
Zomwe zimakhudza kuwira kwa triethylamine
Kuwira kwa triethylamine kumakhudzidwa makamaka ndi kapangidwe kake ka maselo ndi mphamvu za intermolecular. Triethylamine ndi tertiary amine yomwe mawonekedwe ake a molekyulu amakhala ndi atomu ya nayitrogeni yolumikizidwa ndi magulu atatu a ethyl. Chifukwa pali ma elekitironi amodzi okha pa atomu ya nayitrogeni mu molekyulu ya triethylamine, sikophweka kuti triethylamine ipange ma hydrogen bond. Izi zimapangitsa mphamvu za intermolecular za triethylamine makamaka mphamvu za van der Waals, zomwe zimakhala zofooka. Zotsatira zake, kuwira kwa triethylamine kumakhala kochepa.
Unyolo wa hydrocarbon mu molekyulu ya triethylamine ndi hydrophobic, yomwe imakhudzanso kuwira kwake. Triethylamine ili ndi kulemera kwake kwa mamolekyulu poyerekeza ndi ma amines ena ofanana, omwe amafotokoza pang'ono kuwira kwake. Kuphatikizika kwa ma cell ndi mphamvu za intermolecular za triethylamine kumatsimikizira kuwira kwake kwa 89.5 ° C. Malo otentha a triethylamine ndi ntchito ya maselo a amine.
Kufunika kwa malo otentha a triethylamine mu ntchito zamafakitale
Ndikofunika kumvetsetsa ndikuwongolera kuwira kwa triethylamine popanga mankhwala. Popeza kutentha kwa triethylamine kuli pafupi ndi 90 ° C, kulekanitsa bwino ndi kuyeretsedwa kwa triethylamine kungapezeke mwa kusintha kutentha panthawi yochita ndi kupatukana. Mwachitsanzo, panthawi ya distillation, kuwongolera bwino kutentha pafupi ndi malo otentha a triethylamine kumatha kulekanitsa bwino ndi mankhwala ena okhala ndi mfundo zowira zosiyanasiyana. Kudziwa kuwira kwa triethylamine n'kofunikanso kuti munthu agwire bwino ntchito kuti apewe kuwonongeka kosafunikira kapena ngozi chifukwa cha kutentha kwambiri.
Mapeto
Triethylamine ili ndi kuwira kwa 89.5 ° C. Katunduyu amatsimikiziridwa ndi kapangidwe kake ka maselo ndi mphamvu za intermolecular. M'makampani opanga mankhwala, kuwongolera bwino kwa malo otentha a triethylamine ndikofunikira kuti pakhale zokolola komanso chitetezo. Kumvetsetsa kuwira kwa triethylamine sikumangothandiza kukhathamiritsa njira yopangira, komanso kumapereka chitsogozo chofunikira pakuchita bwino.
