Qhov sib txawv tseem ceeb ntawm urea thiab potassium sulphate yog lawv qhov tseem ceeb ua chiv. Urea yog ib qho tseem ceeb hauv kev muab cov nroj tsuag nrog nitrogen, uas tuaj yeem txhawb cov nplooj ntsuab loj hlob, qhov uas cov poov tshuaj sulfate tseem ceeb hauv kev muab cov nroj tsuag nrog cov tshuaj potassium thiab sulfur.
Urea tuaj yeem piav qhia raws li cov organic compound uas muaj cov tshuaj formula CO (NH2) 2, thaum potassium sulfate yog cov organic compound uas muaj cov tshuaj formula K2SO4.
YUrea yog dab tsi?
Urea yog cov organic compound uas muaj cov tshuaj formula CO(NH2)2. Nws feem ntau hu ua carbamide, thiab. Nws yog ib hom amide uas muaj ob pawg amino uas txuas nrog lub hauv paus carbonyl carbon atom. Urea molecule yog ib qho qauv molecule uas cov khoom urea muaj cov pa oxygen koom nrog ob N-H-O hydrogen bonds. Cov pa roj carbon atom hauv urea molecule muaj sp2 hybridization. Tsis tas li ntawd, C-N daim ntawv cog lus ntawm cov molecule muaj qhov tseem ceeb ntawm ob daim ntawv cog lus. Txawm li cas los xij, cov pa oxygen atom hauv pawg carbonyl muaj qhov pib thaum piv rau formaldehyde. Tsis tas li ntawd, qhov sib xyaw no muaj cov dej solubility siab, uas qhia txog nws lub peev xwm los koom nrog hydrogen bonding nrog dej molecules.
Feem ntau, cov tshuaj urea nyiam ua lub luag haujlwm tseem ceeb thaum lub sij hawm metabolism ntawm nitrogen-muaj cov tebchaw hauv cov tsiaj, thiab cov tshuaj no yog cov khoom muaj nitrogen loj hauv cov zis dhau los ntawm cov tsiaj. Nws yog cov khoom tsis muaj xim, tsis muaj ntxhiab tsw thiab muaj cov dej solubility siab. Tsis tas li ntawd, nws yog ib qho tsis muaj tshuaj lom, thiab thaum nws yaj hauv dej, cov kua dej ntawm urea tsis yog acidic lossis alkaline.
Thaum xav txog lwm yam kev siv urea, nws muaj txiaj ntsig zoo hauv kev ua liaj ua teb thiab yog ib feem ntawm nitrogen-tso chiv. Qhov no yog vim urea muaj cov ntsiab lus nitrogen siab, thiab nws muaj tus nqi thauj mus los tsawg rau ib chav tsev nitrogen. Ntxiv mus, urea yog ib qho tseem ceeb raws li cov khoom siv raw rau kev tsim cov urea-formaldehyde resins thiab urea-melamine-formaldehyde cov ntaub ntawv.
YPotassium Sulphate yog dab tsi?
Potassium sulfate (0r sulphate) yog cov organic compound uas muaj cov tshuaj formula K2SO4. Nws tseem hu ua sulphate ntawm potash lossis potash ntawm sulfur. Nws yog ib qho inorganic compound uas tshwm sim raws li ib tug dawb-xim compound uas yog dej-soluble. Feem ntau, cov tshuaj no yog siv los tsim cov chiv, uas tuaj yeem muab cov poov tshuaj thiab sulfur atoms rau thaj tsam xav tau.
Daim duab 01: Potassium Sulfate
Cov khoom siv ntuj tsim ntawm cov poov tshuaj sulfate suav nrog cov zaub mov xws li kainite, schonite, leonite, langbeinite, thiab polyhalite. Peb tuaj yeem cais cov poov tshuaj sulfate los ntawm cov zaub mov no vim tias cov ntsev sib xyaw yog cov dej-soluble tsawg dua. Ntxiv mus, peb tuaj yeem ua ke keserite nrog kev daws ntawm potassium chloride los tsim cov poov tshuaj sulfate.
Daim duab 02: Cov Qauv Ua Haujlwm ntawm Beta Potassium Sulfate
Muaj ob hom potassium sulfate li orthorhombic potassium sulfate thiab tetrahedral potassium sulfate. Ntawm lawv, daim ntawv orthorhombic feem ntau paub. Cov no yog cov qauv complex heev. Orthorhombic potassium sulfate hloov mus rau hauv alpha potassium sulfate ntawm qhov kub thiab txias.
Qhov txawv ntawm Urea thiab Potassium Sulphate yog dab tsi?
Urea thiab potassium sulfate yog cov khoom tseem ceeb hauv kev ua liaj ua teb ua chiv. Qhov sib txawv tseem ceeb ntawm urea thiab potassium sulphate yog tias urea, raws li cov chiv, yog qhov tseem ceeb hauv kev muab cov nroj tsuag nrog nitrogen, uas tuaj yeem txhawb cov nplooj ntsuab loj hlob, thaum potassium sulfate, ua chiv, yog ib qho tseem ceeb hauv kev muab cov nroj tsuag nrog cov tshuaj potassium thiab sulfur..
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm urea thiab potassium sulphate hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Urea vs Potassium Sulphate
Urea tuaj yeem piav qhia raws li cov organic compound uas muaj cov tshuaj formula CO (NH2) 2. Potassium sulfate yog cov organic compound uas muaj cov tshuaj formula K2SO4. Qhov sib txawv tseem ceeb ntawm urea thiab potassium sulphate yog tias urea, raws li cov chiv, yog qhov tseem ceeb hauv kev muab cov nroj tsuag nrog nitrogen, uas tuaj yeem txhawb cov nplooj ntsuab loj hlob, thaum potassium sulfate, ua chiv, yog ib qho tseem ceeb hauv kev muab cov nroj tsuag nrog cov tshuaj potassium thiab sulfur..
