Kuongorora kwakadzama kweBoiling Point yeTriethylamine
Triethylamine (TEA kwenguva pfupi) inowanzoitika musanganiswa weamine wekirasi yemakemikari. Inoshandiswa zvakanyanya mumaindasitiri mazhinji akadai semishonga, mishonga yezvipembenene, madhayi, zvinonyungudutsa uye zvichingodaro. Sekemikari inowanzo shandiswa, izvo zvemuviri zveTriethylamine, kunyanya kubikira kwayo, zvimiro zvinoda kunyatso kunzwisiswa uye kudzorwa mumazhinji maitiro emakemikari. Mubepa rino, tichakurukura nezvekufashaira kwetriethylamine zvakadzama, kuongorora zvikonzero zve physicochemical shure kwayo, uye kukosha kwayo mumashandisirwo anoshanda.
Mhedziso yenzvimbo yekubikira ye triethylamine
Panofashaira yetriethylamine i89.5°C (193.1°F), inova tembiricha yayo yekufashaira payakajairwa atmospheric pressure (1 atm). Kuvira kwekushisa (boiling point) itembiricha apo mhute yemvura yakaenzana neyekunze, zvichireva kuti patembiricha iyi triethylamine inoshanduka kubva pamvura ichienda kune gasi. Boiling point chinhu chakakosha chemuviri wechinhu uye chakakosha pakunzwisisa maitiro e triethylamine pasi pemamiriro akasiyana.
Zvinhu zvinokanganisa nzvimbo yekubikira ye triethylamine
Iyo yekubikira poindi ye triethylamine inonyanya kupesvedzerwa neiyo molecular chimiro uye intermolecular masimba. Triethylamine is tertiary amine ine molecular chimiro chine atomu yenitrogen yakasungirirwa kumapoka matatu ethyl. Nekuti pane peya imwe chete yemaerekitironi paatomu renitrogen mumorekuru wetriethylamine, hazvisi nyore kuti triethylamine igadzire mabhondi ehydrogen. Izvi zvinoita kuti intermolecular forces ye triethylamine kunyanya van der Waals masimba, ayo asina kusimba. Somugumisiro, nzvimbo yekubikira ye triethylamine inenge yakaderera.
Iyo hydrocarbon cheni mu triethylamine molecule ine imwe hydrophobic, iyo inewo mhedzisiro pairi kuvira kwayo. Triethylamine ine huremu huri pakati nepakati kana ichienzaniswa nemamwe maamine akafanana, ayo anotsanangura zvishoma painofashaira. Iko kusanganiswa kweiyo molecular chimiro uye intermolecular masimba e triethylamine inosarudza kuvira kwayo kwe89.5 ° C. Iyo yekubikira poindi ye triethylamine zvakare basa reiyo molecular chimiro cheamine.
Kukosha kweiyo yekubikira poindi ye triethylamine mumaindasitiri ekushandisa
Izvo zvakakosha kuti unzwisise uye udzore iyo yekubikira poindi ye triethylamine mukugadzirwa kwemakemikari. Sezvo nzvimbo yekubikira ye triethylamine iri pedyo ne90 ° C, kupatsanurwa kwakanaka uye kucheneswa kwe triethylamine kunogona kuwanikwa nekugadzirisa kutonhora panguva yekuita uye kuparadzana. Semuenzaniso, panguva yedistillation, kunyatso kudzora tembiricha padyo nenzvimbo yekuvira ye triethylamine inogona kunyatsoiparadzanisa kubva kune mamwe makomisheni ane mapoinzi akasiyana. Kuziva pairi kufashaira yetriethylamine kwakakoshawo kuti ushande zvakachengeteka kudzivirira kurasikirwa kusingaite kana njodzi dzekuchengetedza nekuda kwekunyanya kupisa.
Mhedziso
Triethylamine ine poindi yekuvira ye89.5°C. Ichi chivakwa chemuviri chinotemerwa neyakaomesesa chimiro uye intermolecular masimba. Muindasitiri yemakemikari, kunyatso kudzora kweinofashaira yetriethylamine kwakakosha pakubudirira nekuchengetedza. Kunzwisisa nzvimbo yekubikira ye triethylamine haingobatsiri kukwidziridza maitiro ekugadzira, asi zvakare inopa nhungamiro yakakosha mukushanda kunoshanda.
