Qhov sib txawv tseem ceeb ntawm phosphine thiab phosgene yog phosphine yog ib qho inorganic compound, whereas phosgene yog ib qho organic compound.
Ob leeg phosphine thiab phosgene yog cov roj tsis muaj xim. Txawm hais tias lawv lub npe zoo sib xws, lawv yog ob qho sib txawv.
Phosphine yog dab tsi?
Phosphine yog ib qho inorganic compound uas muaj cov tshuaj PH 3Nws yog cov roj uas tsis muaj xim thiab nplaim taws muaj cov ntxhiab tsw me ntsis. Cov ntxhiab tsw tsis zoo tshwm sim vim muaj qhov hloov pauv phosphine thiab diphosphane. Tsis tas li ntawd, qhov sib xyaw no yog cov pa roj lom. Thiab, cov roj no spontaneously burns nyob rau hauv cov huab cua, ua ib tug luminous nplaim. Tsis tas li ntawd, nws hlawv, tsim phosphoric acid raws li huab cua ntom ntom.
Daim duab 01: Cov qauv ntawm Phosphine
Cov molar loj ntawm cov tshuaj no yog 33.99 g / mol. Lub melting point yog -132.8 ° C thaum lub boiling point - 87.7 ° C. Thaum xav txog cov qauv, nws yog trigonal pyramidal molecule. Lub kaum sab xis ntawm H-P-H daim ntawv cog lus yog 93.5 °. Ntxiv mus, nws muaj ib lub sij hawm dipole vim muaj ib leeg electron khub; Lub sijhawm dipole ntawm cov molecule no nce nrog kev hloov ntawm methyl pawg, thaum nws txo qis nrog kev hloov ntawm ammonia.
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. Tsis tas li ntawd, nws yog insoluble hauv dej tab sis tuaj yeem ua rau dej. Nws muaj trigonal planar geometry, thiab Cl-C-Cl daim ntawv cog lus lub kaum sab xis yog 111.8 °. Ntxiv mus, cov tshuaj no yog ib qho yooj yim acyl chloride uas tsim los ntawm carbonic acid.
Daim duab 02: Cov qauv ntawm Phosgene
Nyob rau hauv kev lag luam nplai, peb tsim phosgene dhau los ntawm cov pa roj carbon monoxide ntshiab 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 lub sij hawm 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.
Qhov txawv ntawm Phosphine thiab Phosgene yog dab tsi?
Txawm hais tias lub npe phosphine thiab phosgene suab zoo sib xws, lawv yog ob qho sib txawv. Qhov sib txawv tseem ceeb ntawm phosphine thiab phosgene yog tias phosphine yog ib qho inorganic compound, hos phosgene yog ib qho organic compound. Tsis tas li ntawd, phosphine tshwm sim raws li cov xim tsis muaj xim, flammable thiab toxic gas nrog ib tug me ntsis tsis kaj siab tsw thaum phosgene tshwm sim raws li ib tug tsis muaj kob roj nrog cov tsw ntawm freshly txiav nyom. Thaum xav txog cov qauv, lub geometry ntawm phosphine molecule yog trigonal pyramidal, thaum lub geometry ntawm phosgene yog trigonal planar. Tsis tas li ntawd, phosphine tsis zoo nyob rau hauv dej, tab sis phosgene yog insoluble, thiab yog tias peb ntxiv rau hauv dej, nws tuaj yeem hnov mob nrog dej es tsis yog soluble xwb.
Hauv qab infographic qhia txog qhov sib txawv ntawm phosphine thiab phosgene, sib piv.
Summary – Phosphine vs Phosgene
Txawm hais tias lub npe phosphine thiab phosgene suab zoo sib xws, lawv yog ob qho sib txawv. Feem ntau, qhov sib txawv tseem ceeb ntawm phosphine thiab phosgene yog tias phosphine yog ib qho inorganic compound, whereas phosgene yog ib qho organic compound.
