Tsanangudzo yeruzivo
18-korona-6is cyclic ether inoumbwa nemakemikari formula c12H24O6. Iyo inonzi "18-korona-6" nekuti ine chindori chematanho matanhatu eokisijeni, kugadzira korona-chimiro, uye ine 18 kabhoni maatomu mune yakazara. Iyo isina ruvara, crystalline yakasimba iyo inonyungudika mune organic soles asi kusanzwisisika mumvura.
Iro zita rekuti "korona" rinotorwa kubva kuyakagadzirwa Ichi chimiro chakasarudzika chinopa 18-korona-6 zvikamu zvina zvakakosha uye zvinoita kuti iwanikwe zvakanyanya mukushandisa kwakasiyana siyana.
Chimwe chehunhu hwakakosha hwe 18-korona-6 kugona kwayo kuomarara nesimbi ion. Maatomu eokisijeni ari mumhete yekorona anogona kuronga pamwe nezvirungu zvevasimbi, senge potassium, sodium, kana calcium, kugadzira yakagadzikana yekudyidzana. Ichi chivakwa chinoita 18-korona-6 iyo inoshandiswa zvakanyanya munzvimbo yemunda wekurambidza kemikistry.
Application
Kuomarara kwesimbi ion ne 18-korona-6 kunogona kuve neye akati wandei maficha:
Phase kuendesa catalyst:SaBenzyltrimetimmemonium chloride, 18-korona-6 inogonawo kuita sechiitiko chekutamisa cheshanduko. Iyo inobatsira pakutamisa mhuka dzakapomedzerwa, dzakadai sesimbi ion, pakati pekusavimbika zvikamu, zvichikurudzira maitiro ayo angave akaoma kana kuti zvisingaite. Iyo korona inosimbisa cavity inogona kusimbisa zvesimbi, kuvabvumira kupfuudza kuburikidza nememberani kana kuendesa pakati peakasiyana sol.
Metal ion kubviswa uye kupatsanurwa:18-korona - Kugona kwayo kusunga pamwe nezvimwe zvataurwa zvesimbi kunobvumira kuzviparadzanisa nekucheneswa kweiyi ion kubva musanganiswa.
Ion kuzivikanwa uye kunzwa:Iko kuoma kwesimbi ioni 18-korona-6 kunogona kushandiswa mukugadzirwa kwemakemikari sensors uye ion-anosarudza electrodes. Nekubatanidza 18-korona-6 kuita sensor masystems, zvinokwanisika kuona uye kuyera chaiyo simbi ion zvichienderana nehukama hwavo kune korona yambiro yekorona.
Masisitimu anodhaka:Iko kugona kwegumi nemasere-korona-6 kuumba zvakaoma neesimbi ion inogona kushandiswa mune zvinodhaka zvinodhaka. Nekuchinja kwesimbi ioni mukati mekorona inoshamisira cavity, zvinokwanisika kuchengetedza simbi ion panguva yekufambisa uye kuvasunungura nenzira inodzorwa panzvimbo yekutarisirwa.
ZVAKAWANDA, Yayo yakasarudzika korona ether chimiro uye kuomarara zvivakwa zvinoita chishandiso chakakosha muminda dzakasiyana siyana emakemikari uye zvigadzirwa zvesainzi.
