Qhov Tseem Ceeb Qhov txawv - Acid Anhydride vs Basic Anhydride
Ib qho anhydride yog cov tshuaj lom neeg tau txais nrog tshem tawm cov dej sib xyaw los ntawm niam txiv cov khoom sib xyaw. Muaj cov organic anhydrides thiab inorganic anhydrides cais raws li muaj C thiab H atoms. Cov anhydrides tuaj yeem yog acid anhydrides lossis cov anhydrides yooj yim. Feem ntau ntawm cov oxides tsim los ntawm kev tshem tawm cov dej los ntawm cov kua qaub yog hu ua acid anhydride. Basic los yog base anhydrides yog cov tebchaw tsim los ntawm kev tshem tawm cov dej los ntawm lub hauv paus. Qhov sib txawv tseem ceeb ntawm acid anhydrides thiab base anhydrides yog cov kua qaub anhydrides yog tsim los ntawm cov kua qaub thaum cov anhydrides yooj yim yog tsim los ntawm cov hauv paus.
Acid Anhydride yog dab tsi?
Acid anhydrides yog cov tshuaj lom neeg hu ua oxides uas yog tsim los ntawm kev tshem tawm cov dej los ntawm cov kua qaub. Cov kua qaub yog cov tshuaj lom neeg uas tuaj yeem pub H+ ions (protons) rau nruab nrab. Tab sis thaum cov kua qaub hloov mus rau ib qho anhydride, nws tsis tuaj yeem tso H+ ions. Cov kua qaub anhydride yog qhov tseem ceeb ntawm ob pawg acyl sib txuas rau tib lub atom oxygen (-C(=O)-O-C(=O)). Acid oxides feem ntau hu ua acid anhydrides.
Daim duab 01: Ib qho Acid anhydride muaj ob pawg acyl sib txuas los ntawm ib lub atom oxygen (muab xiav).
Cov chav kawm feem ntau ntawm cov kua qaub anhydrides yog cov organic acid anhydrides. Cov no yog cov organic tebchaw tseem ceeb. Ib qho tseem ceeb tshaj plaws organic acid anhydrides yog carboxylic anhydride. Tseem muaj inorganic acid anhydrides thiab. Cov no yog cov tshuaj inorganic tseem ceeb thiab tsis muaj cov organic moiety. Piv txwv li, CO2 (carbon dioxide) yog cov kua qaub anhydride muab los ntawm carbonic acid (H2CO 3). Qee qhov piv txwv tau muab hauv qab no.
- YOrganic acid anhydrides
- Acetic anhydride (qhov yooj yim tshaj plaws organic acid anhydride)
- Maleic anhydride
- ATP hauv nws daim ntawv protonated
- Acetic, formic anhydride
- Inorganic acid anhydrides
- Silicon dioxide (SiO2)
- Vanadium pentoxide (V2O5)
- Sulfur trioxide (SO3)
- Chromium trioxide (Cr2O3)
Muaj ntau txoj hauv kev los tsim cov kua qaub anhydrides. Acid anhydrides yog tsim los ntawm cov pab pawg acyl reactive heev. Lub reactivity zoo li acyl halides. Txawm li cas los xij, cov kua qaub anhydrides zoo li electrophilic tsawg dua acyl halides.
Dab tsi yog Basic Anhydride?
Ib qho yooj yim anhydride lossis base anhydride yog cov hlau oxide uas tsim cov tshuaj yooj yim thaum ua rau dej. Cov hlau oxide no feem ntau yog alkali hlau oxide lossis alkaline ntiaj teb hlau oxide (oxides ntawm pawg 1 lossis pawg 2).
Daim duab 02: Magnesium Oxide Powder, uas yog ib qho yooj yim Anhydride.
Cov anhydrides yooj yim no yog tsim los ntawm kev tshem cov dej los ntawm cov khoom siv hydroxide. Piv txwv li, qhov yooj yim anhydride Na2O yog tsim los ntawm nws cov hydroxide, NaOH. Qee qhov piv txwv rau cov anhydrides yooj yim tau muab hauv qab no.
- Sodium oxide (Na2O)
- Potassium oxide (K2O)
- Magnesium oxide (MgO)
- Casium Oxide (CaO)
- Barium oxide (BaO)
Dab tsi zoo sib xws ntawm Acid Anhydride Basic Anhydride?
- Ob lub Acid Anhydride thiab Basic Anhydride yog tsim los ntawm kev tshem tawm cov dej los ntawm cov tshuaj lom neeg.
- Ob lub Acid Anhydride thiab Basic Anhydride tuaj yeem hloov mus rau hauv daim ntawv hydride los ntawm kev ntxiv dej.
