Qhov sib txawv tseem ceeb ntawm cov organic thiab inorganic phosphate yog cov organic phosphates yog phosphates ntawm esters whereas cov inorganic phosphates yog ntsev ntawm phosphoric acid.
Phosphates yog cov tshuaj sib xyaw uas muaj phosphate anions (PO4– anion). Ob hom tseem ceeb ntawm cov tebchaw no yog cov organic phosphates thiab inorganic phosphates. Cov tebchaw no muaj cov tshuaj lom neeg thiab lub cev sib txawv; yog li ntawd, kev siv sib txawv hauv kev lag luam. Cia peb mus saib cov ntsiab lus ntxiv txog lawv.
Organic Phosphate yog dab tsi?
Organic phosphates yog phosphates ntawm esters. Peb hu lawv "organophosphates". Cov no yog esters ntawm phosphoric acid. Txij li cov tshuaj formula ntawm phosphoric acid yog H3PO4, ester cov ntaub ntawv thaum cov kua qaub no hloov lub hydrogen atom ntawm hydrocarbon. Yog li ntawd, inorganic acid ua organic. Cov organic phosphates no muaj txiaj ntsig zoo rau kev ua liaj ua teb. Piv txwv li, peb siv cov tshuaj tua kab organophosphate xws li parathion, malathion, dichlorvos, thiab lwm yam.
Daim duab 01: Cov qauv dav dav ntawm Organophosphates
Cov pawg organic ntawm cov tebchaw no tuaj yeem txuas nrog ib leeg los tsim cov phosphate tshiab. Yog tias cov tshuaj no muaj cov pab pawg hydroxyl, lawv muaj qhov acidic. Qhov no yog vim hais tias, nyob rau hauv ib tug aqueous tov, cov tebchaw yuav tso cov proton nyob rau hauv hydroxyl pab pawg neeg ua rau cov kua qaub acidic. Tom qab ntawd cov ionized phosphate compound yuav txuas nrog lwm pawg organic tsim cov tebchaw tshiab. Ntxiv nrog rau kev siv cov chiv, cov tshuaj no muaj txiaj ntsig zoo li additives, solvents, plasticizers, etc.
Inorganic Phosphate yog dab tsi?
Inorganic phosphates yog ntsev ntawm phosphoric acid. Hauv cov tebchaw no, peb tuaj yeem pom ib pawg phosphate txuas nrog cov hlau cation. Yog li ntawd, phosphate pab pawg ua raws li anion. Tag nrho cov nqi ntawm no anion yog -3. Qhov no qhia tau hais tias qhov no anion tuaj yeem koom nrog hauv kev tsim ntawm monobasic, dibasic thiab tribasic ntsev. Cov pab pawg phosphate muaj cov txheej txheem tetrahedral. Inorganic phosphates tshwm sim raws li cov ntsev ntawm pab pawg 1 hais. Piv txwv li: sodium (Na), poov tshuaj (K), calcium (Ca), thiab lwm yam.
Daim duab 02: Phosphate Anion
Ob qhov loj inorganic phosphate tebchaw yog orthophosphates thiab condensed phosphates. Ntawm lawv, orthophosphates yog reactive heev, thiab cov no yog cov yooj yim inorganic phosphates. Lawv tsuas muaj ib chav phosphate ib molecule. Condensed phosphates muaj ntau tshaj ib chav tsev phosphate. Cov tebchaw no tseem muaj txiaj ntsig zoo li chiv, xws li: superphosphate thiab triple superphosphate.
Qhov txawv ntawm Organic thiab Inorganic Phosphate yog dab tsi?
Organic phosphates yog phosphates ntawm esters. Hauv cov organic phosphates, pawg phosphate thiab pawg organic txuas nrog ib leeg ntawm covalent bonds. Ntxiv mus, lawv tsuas muaj pawg organic txuas nrog phosphate pawg. Inorganic phosphates yog ntsev ntawm phosphoric acid. Hauv inorganic phosphates, phosphate anions thiab hlau cations muaj electrostatic attraction quab yuam ntawm lawv. Tsis tas li ntawd, lawv muaj pawg inorganic txuas nrog phosphate pawg uas tsis yog hlau cation. Cov no yog qhov sib txawv tseem ceeb ntawm cov organic thiab inorganic phosphate.
Summary – Organic vs Inorganic Phosphate
Phosphate tebchaw muaj nyob rau hauv ob hom raws li cov organic phosphates thiab inorganic phosphates raws li cov qauv tshuaj. Qhov sib txawv ntawm cov organic thiab inorganic phosphate yog cov organic phosphates yog phosphates ntawm esters whereas cov inorganic phosphates yog ntsev ntawm phosphoric acid.
