Tetrabutylammonium bromide (TBAB),MF is C16H36BrN, is a quaternary ammonium salt. Inowanzoshandiswa sechikamu chekufambisa catalyst uye mune organic synthesis. TBAB iwhite crystalline poda ine CAS nhamba 1643-19-2. Nekuda kwehunhu hwayo hwakasiyana, iyo yakakosha reagent mune akasiyana makemikari maitiro. Mubvunzo wakajairika maererano neTBAB kunyungudika kwayo mumvura. Pamusoro pezvo, pane kazhinji kunetseka nezve TBAB ine chepfu here? Muchikamu chino, tichaongorora kunyungudika kweTBAB mumvura uye TBAB ine muchetura here?
Chekutanga, ngatitarisei kunyungudika kweTBAB mumvura.Tetrabutylammonium bromideinonyungudika zvishoma mumvura. Nekuda kweiyo hydrophobic hunhu, ine yakaderera solubility mu polar solvents, kusanganisira mvura. Nekudaro, TBAB inonyungudika zvakanyanya muorganic solvents senge acetone, ethanol, uye methanol. Ichi chivakwa chinoita kuti ive yakakosha musanganiswa mune organic synthesis uye akasiyana makemikari maitiro anoda chikamu chekufambisa catalysts.
TBABinoshandiswa zvakanyanya sechikamu chekufambisa chinokonzeresa mune organic chemistry, ichibatsira kuendesa mareactants kubva kune chimwe chikamu kuenda kune chimwe. Iyo inosimudzira maitiro pakati peimmiscible reactants nekufambisa ions kana mamorekuru kubva kune chimwe chikamu kuenda kune chimwe, nekudaro kuwedzera maitiro ekuita uye goho. Pamusoro pezvo, TBAB inogona zvakare kushandiswa mukubatanidza zvinodhaka, makemikari ekurima uye mamwe makemikari akanaka. Kukwanisa kwayo kuwedzera maitiro ekuita uye kusarudzwa kunoita kuti ive chinhu chinokosha chekugadzirwa kwemhando dzakasiyana-siyana.
Zvino, ngatikurukurei ndizvoTBABzvine chepfu? Tetrabutylammonium bromide inoonekwa seine chepfu kana ikanwiwa, ikafemerwa, kana kusangana neganda. Izvo zvakakosha kubata iyi komputa nekuchenjerera uye nekutevera kuchengetedzwa kwakaringana kana uchiishandisa. Kufema kweTBAB kunogona kukonzera kushatirwa kwekufema, uye kubata kweganda kunogona kukonzera kushatirwa uye dermatitis. Kunwa kweTBAB kunogona kukonzera gastrointestinal kutsamwa uye zvimwe zvinokanganisa. Naizvozvo, kushandiswa kwemidziyo yekudzivirira yakafanira (semuenzaniso, magirovhosi nemajasi erabhoritari) kwakakosha pakubata TBAB.
Uyezve,TBABinofanira kuraswa maererano nemitemo yemarara ine ngozi yemunharaunda uye mazano. Nzira dzakakodzera dzekuchengeta uye dzekurasa dzinofanirwa kuteverwa kudzivirira kusvibiswa kwezvakatipoteredza uye kukuvadza kungangoita hutano hwevanhu.
Muchidimbu,tetrabutylammonium bromide (TBAB)inonyungudika zvishoma mumvura asi inonyungudika zviri nyore muzvinonyungudutsa, zvichiita kuti ive komboni yakakosha muorganic synthesis uye phase transfer catalysis. Kushandiswa kwayo muorganic chemistry, kugadzirwa kwezvinodhaka uye mamwe maitiro emakemikari anosimbisa kukosha kwayo mumunda wemakemikari ekutsvagisa nekugadzira. Nekudaro, zvakakosha kuti uzive huturu hunogona kuitika hweTBAB uye kutora matanho anodiwa pakubata nekurasa komisheni iyi. Kutevedzera zvirevo zvekuchengetedza uye nhungamiro kwakakosha kuti uve nechokwadi chekushandiswa kwakachengeteka kweTBAB uye kuderedza chero njodzi dzine chekuita.
