Intshayelelo

I-2-(i-chloromethyl) -5- (trifluoromethyl) -1,3,4-oxadiazole i-organic compound kunye ne-formula C4H2ClF3N2O.

 

Indalo:

I-2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole ngulwelo olungenambala ukuya kumthubi oluluthuthu okanye oluqinileyo lwecrystalline. Inozinzo oluphezulu lwe-thermal kunye ne-inertness yekhemikhali. Ayinyibiliki emanzini kwiqondo lobushushu begumbi, inyibilika kwezinye izinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-ether. Ikhompawundi inokubonakaliswa ngobuchule obufana neresonance yemagnethi yenyukliya kunye nemass spectrometry.

 

Sebenzisa:

I-2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole inexabiso elithile lesicelo kwintsimi ye-chemistry. Ihlala isetyenziswa njengendawo ephakathi kwi-organic synthesis yokwenziwa kwezinye iikhompawundi. Ukongeza, ikwasetyenziswa njenge-reagent yophando kwicandelo lokubulala izitshabalalisi kunye neyeza.

 

Indlela yokulungiselela:

I-2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole inokwenziwa ngeendlela ezahlukeneyo. Oku kulandelayo yindlela eqhelekileyo yokulungiselela:

 

1. Yongeza i-catalyst (efana ne-triethylamine) kwi-anhydrous organic reaction solvent system.

2. Yongeza inani elithile le-methyl 3-chloropropionate kunye ne-methyl trifluoroformate kwinkqubo ye-solvent.

3. I-reaction iqhutyelwa kwiqondo lokushisa elifanelekileyo phantsi kwe-inert atmosphere, kwaye ngokuqhelekileyo kuyimfuneko ukutshisa umxube wokuphendula.

4. Ukucoca okanye ukuxutywa kwe-distillation ukufumana imveliso, emva kokucocwa okufanelekileyo kunye nokomisa ukufumana imveliso ecocekileyo.

 

Ulwazi ngoKhuseleko:

I-2-(chloromethyl) -5-(trifluoromethyl) -1,3,4-oxadiazole ngokuqhelekileyo ikhuselekile xa isetyenziswe kwaye igcinwe ngokuchanekileyo. Nangona kunjalo, njengekhompawundi ephilayo, inokubangela ingozi ethile kwimpilo yabantu kunye nokusingqongileyo. Ekusetyenzisweni nasekuphatheni, kufuneka kulandele iinkqubo ezichanekileyo zokhuseleko, kwaye ugweme ukudibana ngokuthe ngqo. Imiyalelo yokhuseleko efanelekileyo yekhompawundi kufuneka ifundwe ngononophelo kwaye ilandelwe. Ukuba kuyimfuneko, umsebenzi kufuneka wenziwe phantsi kwesikhokelo sabasebenzi abaqeqeshiweyo.
