Green chemistry yakawana kutariswa kwakakosha mumakore achangopfuura nekuda kwekutarisa kwayo kune yakagadzikana uye ine hushamwari maitiro.Imwe nzvimbo yakaona kufambira mberi kukuru kusimudzira uye kushandiswa kwezvinokonzeresa zvinogona kusimudzira maitiro eco-hushamwari.Tetrabutylammonium iodide (TBAI) yakabuda seimwe inokonzeresa, iine yakasarudzika zvimiro ichiita kuti ive mumiriri akakodzera kusimudzira shanduko yegirinhi kemikari.
TBAI, ine nhamba yeCAS 311-28-4, inonzi quaternary ammonium munyu inoumbwa ne tetraalkylammonium cation uye anion iodide.Iyo chena crystalline yakasimba inonyungudika zvakanyanya mune zvakajairika organic solvents.TBAI yakadzidzwa zvakanyanya uye yakashandiswa sechinhu chinokonzeresa mune akasiyana organic maitiro, ichiratidza kushanda kwayo uye kuita kwakasiyana-siyana mukusimudzira girinhi chemistry.
Imwe yemabhenefiti akakosha ekushandisa TBAI kugona kwayo kukurumidza kuita maitiro uku ichideredza kudiwa kwehasha maitiro mamiriro.Traditional organic synthesis inowanzoda kupisa kwakanyanya uye kumanikidzwa, pamwe nekushandiswa kwechepfu uye zvine njodzi reagents.Mamiriro aya haangokonzeri njodzi kune zvakatipoteredza asiwo anotungamirira kukugadzirwa kwemarara akawanda.
Kusiyana neizvi, TBAI inogonesa maitiro kuti aenderere mberi zvine hunyoro mumamiriro ezvinhu akapfava, kuderedza kushandiswa kwesimba uye kuderedza kugadzirwa kwemarara.Izvi zvinonyanya kubatsira kune maindasitiri-scale maitiro, uko kutorwa kwegirinhi chemistry nheyo kunogona kutungamira kune yakakosha mari yekuchengetedza uye mabhenefiti ezvakatipoteredza.
TBAI yakashandiswa zvakabudirira mune dzakasiyana siyana dzegirinhi chemistry shanduko.Yakashandiswa sechinhu chinokonzeresa mukugadzirwa kweakasiyana organic komisheni, kusanganisira mishonga yepakati uye yakanaka makemikari.Pamusoro pezvo, TBAI yakaratidza chivimbiso chikuru mukusimudzira maitiro ane hushamwari kwezvakatipoteredza sekushandurwa kwebiomass kuita biofuel yakakosha uye yakasarudzika oxidation yeorganic substrates.
The unique properties ofTBAIizvo zvinoita kuti ive inokonzeresa mugirini kemikari shanduko iri mukukwanisa kwayo kuita sesese chikamu chekufambisa catalyst uye nucleophilic iodide sosi.Sechikamu chekufambisa chinokonzeresa, TBAI inofambisa kufambisa kwezvinoita pakati pezvikamu zvakasiyana, kuwedzera maitiro ekuita uye nekusimudzira kuumbwa kwezvigadzirwa zvinodiwa.Yayo nucleophilic iodide sosi inoshanda inoibvumira kutora chikamu mukutsiva kwakasiyana uye kuwedzera maitiro, kuunza maatomu ayodhine muma organic molecules.
Uyezve, TBAI inogona kudzoserwa nyore uye kudzokororwa, ichiwedzera kusimudzira kwayo.Mushure mekupedzwa kwekuita, TBAI inogona kupatsanurwa kubva musanganiswa wekuita uye kushandiswazve kune dzinotevera shanduko, kuderedza iyo yose inokonzeresa mutengo uye kuderedza nyaya dzekurasa marara.
Kushandiswa kweTBAI sechinhu chinokonzeresa shanduko yegreen chemistry ingori muenzaniso wekuti vaongorori nenyanzvi dzemaindasitiri vari kuramba vachishanda mukusimudzira maitiro akasimba.Nekushandisa macatalyst anoshanda, anoshanda, uye ane hushamwari kwezvakatipoteredza, tinogona kuderedza zvakanyanya kukanganiswa kwezvakatipoteredza kwemakemikari maitiro, tichiita kuti ive yakasimba uye irambe yakasimba.
Mukupedzisa,Tetrabutylammonium iodide (TBAI)yabuda sechinhu chine simba chinokonzeresa mukushandurwa kwakawanda kwekemikisi yegirini.Kugona kwayo kukurumidzira maitiro ekuita, kusimudzira maitiro eco-hushamwari, uye kudzoreredzwa nyore nyore uye kudzokororwa kunoita kuti ive mumiriri akakodzera wekusimudzira maitiro akasimba uye ane hushamwari.Sezvo vaongorori nenyanzvi dzemaindasitiri vachiramba vachiongorora nekugadzirisa masisitimu anokonzeresa, tinogona kutarisira kuona kufambira mberi kwakatokura mumunda wekemikari yegirinhi, kushandura nzira yatinosvika nayo organic synthesis tichideredza kukanganisa kwezvakatipoteredza.
