Qhov sib txawv tseem ceeb ntawm phosgene thiab diphosgene yog tias phosgene muaj ib qho carbon atom, ib qho oxygen atom thiab ob lub chlorine atoms whereas diphosgene muaj ob npaug ntawm tag nrho cov atoms.
Phosgene thiab diphosgene yog cov organic tebchaw. Ob lub tebchaw no muaj carbon, oxygen thiab chlorine atoms. Tus naj npawb ntawm txhua hom atoms hauv diphosgene molecule yog raws nraim ob npaug ntawm cov atoms hauv phosgene molecule.
Phosgene yog dab tsi?
Phosgene yog cov organic compound uas muaj cov tshuaj formula COCl 2 Nws yog cov roj tsis muaj xim, thiab nws muaj ntxhiab tsw zoo ib yam li cov nyom tshiab. Txawm hais tias nws yog insoluble hauv dej, nws tuaj yeem ua rau dej. Ntxiv mus, nws muaj trigonal planar geometry, thiab Cl-C-Cl daim ntawv cog lus lub kaum sab xis yog 111.8 °. Cov tshuaj no yog ib qho yooj yim acyl chloride uas tsim los ntawm carbonic acid.
Daim duab 01: Cov Qauv Tshuaj ntawm Phosgene Molecule
Hauv kev lag luam, peb tsim phosgene los ntawm kev dhau cov pa roj carbon monoxide thiab cov tshuaj chlorine los ntawm cov pa roj carbon activated. Ntawm no, activated carbon yog lub catalyst. Tsis tas li ntawd, cov tshuaj tiv thaiv no yog exothermic, thiab peb yuav tsum txias lub reactor thaum cov tshuaj tiv thaiv. Thaum xav txog kev siv phosgene, peb tuaj yeem siv nws hauv kev tsim cov isocyanates, hauv kev sib txuas ntawm carbonates, thiab lwm yam.
Diphosgene yog dab tsi?
Diphosgene yog cov organic compound uas muaj cov tshuaj formula C2O2Cl4Nws yog cov kua uas tsis muaj xim nyob rau hauv chav tsev kub. Nws yog ib qho tseem ceeb reagent nyob rau hauv cov organic synthesis tshuaj. Piv txwv li, diphosgene muaj toxicity tsawg tshaj phosgene. Txawm li cas los xij, cov kua no yuav tsum tau ua tib zoo saib xyuas dua li phosgene, uas yog roj.
Daim duab 02: Cov Qauv Tshuaj ntawm Diphosgene Molecule
Peb tuaj yeem npaj diphosgene hauv chav kuaj los ntawm radical chlorination ntawm methyl chloroformate. Cov tshuaj tiv thaiv no yuav tsum muaj cov khoom siv hluav taws xob UV. Tsis tas li ntawd, radical chlorination ntawm methyl formate tuaj yeem tsim diphosgene. Ntxiv mus, diphosgene hloov mus rau hauv phosgene thaum rhuab los yog raws li cov tshuaj tiv thaiv nrog charcoal.
Dab tsi yog qhov zoo sib xws ntawm Phosgene thiab Diphosgene?
- Phosgene thiab diphosgene yog cov organic tebchaw.
- Ob lub tebchaw no muaj cov pa roj carbon, oxygen thiab chlorine atoms.
- Cov tshuaj no yog insoluble hauv dej.
Qhov txawv ntawm Phosgene thiab Diphosgene yog dab tsi?
Phosgene yog cov organic compound uas muaj cov tshuaj formula COCl2 hos Diphosgene yog cov organic compound uas muaj cov tshuaj formula C2O 2Cl4. Qhov sib txawv tseem ceeb ntawm phosgene thiab diphosgene yog tias phosgene muaj ib qho carbon atom, ib qho oxygen atom thiab ob lub chlorine atoms whereas diphosgene muaj ob npaug ntawm tag nrho cov atoms.
Phosgene tshwm sim raws li cov roj tsis muaj xim nrog cov ntxhiab tsw zoo ib yam li cov nyom tshiab tshiab thaum diphosgene tshwm sim ua kua tsis muaj xim ntawm chav tsev kub. Piv txwv li, diphosgene tsis muaj tshuaj lom ntau dua li phosgene, tab sis nws yuav tsum tau ua tib zoo saib xyuas vim tias diphosgene muaj lub siab vapor siab thiab decomposes tsim phosgene ntawm qhov kub thiab txias. Ntxiv mus, phosgene yog tsim los ntawm kev dhau cov pa roj carbon monoxide thiab chlorine roj los ntawm cov pa roj carbon activated thaum diphosgene yog tsim los ntawm radical chlorination ntawm methyl chloroformate nyob rau hauv lub xub ntiag ntawm ib tug UV hluav taws xob qhov chaw.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm phosgene thiab diphosgene.
Summary – Phosgene vs Diphosgene
Phosgene thiab diphosgene yog cov organic tebchaw. Ob lub tebchaw no muaj carbon, oxygen thiab chlorine atoms. Qhov sib txawv tseem ceeb ntawm phosgene thiab diphosgene yog tias phosgene muaj ib qho carbon atom, ib qho oxygen atom thiab ob chlorine atoms whereas diphosgene muaj ob npaug ntawm tag nrho cov atoms.
