Qhov sib txawv tseem ceeb ntawm acetamide thiab benzamide yog tias acetamide muaj cov methyl pawg txuas nrog cov pab pawg amide, thaum benzamide muaj lub nplhaib benzene txuas rau amide pawg.

Acetamide thiab benzamide yog cov organic tebchaw uas muaj cov pab pawg ua haujlwm amide. Cov tshuaj formula ntawm amide pawg yog -C(=O)-NH2. Cov pa roj carbonyl carbon atom ntawm pab pawg ua haujlwm no tuaj yeem khi nrog cov tshuaj sib txawv xws li aliphatic pawg thiab cov ntxhiab tsw.

Acetamide yog dab tsi?

Acetamide yog cov organic compound uas muaj cov tshuaj formula CH3CONH2. Nws tseem muaj npe hu ua ethanamide vim muaj cov pab pawg ethane txuas nrog cov pab pawg ua haujlwm amide. Qhov no yog cov tswv cuab yooj yim tshaj plaws ntawm pawg amide ntawm cov tebchaw. Nws yog tsim los ntawm acetic acid. Cov molar loj ntawm cov tshuaj no yog 59 g / mol. Nws yog xim tsis muaj xim, hygroscopic khoom uas tsis muaj ntxhiab thiab. Txawm li cas los xij, muaj qee qhov impurities tuaj yeem ua rau tus nas zoo li tsw hauv cov khoom no.

Daim duab 01: Cov Qauv Tshuaj ntawm Acetamide

Muaj ob txoj hauv kev tsim cov acetamide: txoj kev kuaj thiab txoj kev lag luam. Nyob rau hauv txoj kev kuaj ntau lawm, peb tuaj yeem tsim cov tshuaj no los ntawm ammonium acetate ntawm lub cev qhuav dej. Nws muab acetamide thiab dej ua cov khoom. Hauv txoj kev tsim khoom lag luam, peb tuaj yeem tsim cov tshuaj no los ntawm dehydrating ammonium acetate los yog los ntawm hydration ntawm acetonitrile.

Muaj ntau yam kev siv acetamide, suav nrog kev siv acetamide ua cov yas yas thiab ua cov kuab tshuaj. Tsis tas li ntawd, molten acetamide yog ib qho tseem ceeb ua kuab tshuaj rau ntau daim ntawv thov. Lub dielectric tas li ntawm acetamide yog ntau dua li lwm cov organic solvents, uas ua rau nws muaj peev xwm yaj ntau inorganic tebchaw uas muaj solubility nyob ze ntawm cov dej.

Benzamide yog dab tsi?

Benzamide yog cov organic compound uas muaj cov tshuaj formula C6H5C(O)NH2. Nws yog xim dawb-xim khoom thiab yog qhov yooj yim amide ntawm aromatic amides. Cov tshuaj no tau txais los ntawm benzoic acid.

Daim duab 2: Cov Qauv Tshuaj ntawm Benzamide

Benzamide yog me ntsis dej-soluble tab sis heev soluble nyob rau hauv ntau cov organic solvents. Cov molar loj ntawm cov tshuaj no yog 121.1 g / mol.

Derivatives ntawm benzamide muaj ntau daim ntawv thov hauv kev lag luam kws tshuaj vim lawv cov khoom siv tshuaj xws li tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tiv thaiv kab mob, tshuaj tiv thaiv kab mob, mob plawv, thiab lwm yam khoom..

Hauv chav kuaj, peb tuaj yeem tsim benzamide los ntawm kev sib xyaw benzonitrile nrog cov tshuaj sulfuric acid. Tom qab sib tov ob lub ntsiab lus no, peb tuaj yeem tau txais kev daws teeb meem sai sai. Tom qab ntawd peb yuav tsum tau ua kom sov cov tshuaj ntshiab no nyob rau hauv reflux li ntawm 20 feeb kom tau benzamide.

Qhov txawv ntawm Acetamide thiab Benzamide yog dab tsi?

Acetamide thiab benzamide yog cov organic tebchaw. Acetamide yog cov organic compound uas muaj cov tshuaj formula CH3CONH2 hos Benzamide yog cov organic compound uas muaj cov tshuaj formula C6 H5C(O)NH2 Qhov sib txawv tseem ceeb ntawm acetamide thiab benzamide yog tias acetamide muaj ib pawg methyl txuas rau amide. pab pawg, whereas benzamide muaj ib lub nplhaib benzene txuas rau amide pawg.

Ntxiv mus, peb tuaj yeem tsim cov acetamide los ntawm ammonium acetate los ntawm cov tshuaj tiv thaiv lub cev qhuav dej, thaum benzamide tuaj yeem npaj los ntawm kev sib xyaw benzonitrile nrog sulfuric acid. Tsis tas li ntawd, yog tias peb saib lawv cov kev siv, acetamide yog siv los ua cov yas yas thiab ua cov kuab tshuaj thaum benzamide siv los ua cov khoom xyaw hauv kev lag luam tshuaj.

Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm acetamide thiab benzamide hauv daim ntawv tabular.
