Qhov sib txawv tseem ceeb ntawm acetonitrile thiab acetone yog tias acetonitrile yog nitrile compound, whereas acetone yog ketone.
Ob leeg acetonitrile thiab acetone yog cov organic tebchaw. Qhov ntawd txhais tau tias; Ob lub tebchaw no muaj carbon thiab hydrogen atoms nrog C-H bonds thiab C-C bonds. Cov tebchaw no poob rau hauv ob pawg nyob ntawm cov qauv tshuaj; lawv muaj ntau pab pawg ua haujlwm.
Acetonitrile yog dab tsi?
Acetonitrile yog cov organic compound uas muaj cov tshuaj formula CH3CN. Nws tshwm sim raws li cov kua uas tsis muaj xim, thiab nws muaj ib qho faint, txawv tsw. Nws yog qhov yooj yim tshaj plaws organic nitrile compound. Cov compound no tsuas yog tsim los ntawm cov khoom siv thaum lub sij hawm tsim cov acrylonitrile.
Daim duab 01: Cov qauv ntawm Acetonitrile
Cov molar loj ntawm cov tshuaj no yog 41 g / mol. Nws yog miscible nrog dej thiab qee cov organic solvents zoo li. Acetonitrile muaj cov tshuaj toxicity nruab nrab ntawm cov koob tshuaj me me, tab sis hauv peb lub cev, acetonitrile tuaj yeem ua rau cov txheej txheem metabolic sib txawv, uas ua rau tsim cov hydrogen cyanide, uas yog cov tshuaj lom neeg lom zem heev.
Thaum xav txog cov ntawv thov ntawm acetonitrile, peb tsuas yog siv nws ua cov kuab tshuaj. Thaum lub sij hawm purification ntawm butadiene hauv refineries, acetonitrile yog cov kuab tshuaj uas peb siv. Vim tias qhov sib xyaw no muaj cov dielectric siab tas li, thiab nws muaj peev xwm ua kom yaj cov electrolytes, acetonitrile tseem ceeb hauv kev tsim cov roj teeb thiab. Tsis tas li ntawd, nws muaj txiaj ntsig zoo li cov kuab tshuaj hauv kev siv tshuaj thiab.
Acetone yog dab tsi?
Acetone yog cov organic compound uas muaj cov tshuaj formula (CH3)2CO. Nws tshwm sim raws li ib tug tsis muaj kob thiab flammable kua uas yog volatile heev. Nws yog qhov yooj yim tshaj plaws thiab tsawg tshaj plaws ketone. Nws qhov hnyav yog 58 g / mol. Nws muaj pungent tsw, irritating tsw, thiab miscible nrog dej. Cov compound yog ib txwm ua raws li cov kuab tshuaj polar. Lub polarity yog vim qhov siab electronegativity sib txawv ntawm carbon thiab oxygen atoms ntawm carbonyl pawg. Txawm li cas los xij, nws tsis yog ntau polar; Yog li, nws tuaj yeem yaj ob qho lipophilic thiab hydrophilic tshuaj.
Daim duab 02: Cov qauv tshuaj ntawm Acetone
Peb lub cev tuaj yeem tsim cov acetone hauv cov txheej txheem metabolic, thiab nws raug tshem tawm ntawm lub cev los ntawm cov txheej txheem sib txawv. Hauv kev lag luam nplai, txoj kev tsim khoom suav nrog kev tsim khoom ncaj qha lossis tsis ncaj los ntawm propylene. Cov txheej txheem ntau yog txheej txheem cumene.
Qhov txawv ntawm Acetonitrile thiab Acetone yog dab tsi?
Ob leeg acetonitrile thiab acetone yog cov organic tebchaw. Qhov sib txawv tseem ceeb ntawm acetonitrile thiab acetone yog acetonitrile yog nitrile compound, hos acetone yog ketone. Acetonitrile yog cov organic compound uas muaj cov tshuaj formula CH3CN thaum Acetone yog cov organic compound uas muaj cov tshuaj formula (CH3) 2CO. Ntxiv mus, molar mass ntawm acetonitrile yog 41 g / mol, thaum molar loj ntawm acetone yog 8 g / mol.
Thaum xav txog atomic muaj pes tsawg leeg ntawm txhua qhov sib xyaw, acetonitrile muaj carbon, hydrogen thiab nitrogen atoms whereas acetone muaj carbon, hydrogen thiab oxygen atoms. Tsis tas li ntawd, acetonitrile yog ib qho tseem ceeb raws li cov kuab tshuaj thaum lub sij hawm purification ntawm butadiene nyob rau hauv refineries, raws li ib tug hnyav nyob rau hauv kev lag luam tshuaj, thiab yog tseem ceeb nyob rau hauv manufacturing roj teeb, thiab lwm yam. Acetone yog ib qho tseem ceeb raws li ib tug polar solvent. Tsis tas li ntawd, Acetonitrile yog tshuaj lom me me ntawm koob tshuaj me me thiab muaj kuab lom heev tom qab cov metabolism thaum acetone yog me me toxicity ntawm koob tshuaj ntau.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm acetonitrile thiab acetone.
Summary – Acetonitrile vs Acetone
Ob leeg acetonitrile thiab acetone yog cov organic tebchaw, tab sis lawv muaj cov qauv tshuaj sib txawv thiab sib txawv tshuaj thiab lub cev. Qhov sib txawv tseem ceeb ntawm acetonitrile thiab acetone yog tias acetonitrile yog nitrile compound, hos acetone yog ketone.
