Calcium glycerophosphate yog dab tsi
Calcium glycerophosphate yog cov hmoov dawb los yog daj me ntsis crystalline hmoov, tsis muaj ntxhiab, yuav luag tsis muaj ntxhiab, thiab iab me ntsis. Me ntsis hygroscopic hauv huab cua. Nws poob dej crystal ntawm 130 degree los tsim cov tshuaj anhydrous thiab decomposes saum 170 degree. Txhua g yog yaj nyob rau hauv li 50 ml ntawm 25 degree dej. Nws yog ntau soluble hauv dej thaum qhov kub thiab txias, thiab cov kua dej aqueous yog alkaline. Insoluble hauv ethanol, soluble hauv glycerol. Citric acid lossis lactic acid tuaj yeem txhim kho nws cov solubility hauv dej, tab sis nws yooj yim rau decompose thaum rhuab.
Kev ua haujlwm ntawm Calcium glycerophosphate
Hauv tshuaj, nws yog siv los txhawb cov calcification thiab tsim cov pob txha thiab cov hniav. Khoom noj khoom haus khoom noj khoom haus, zaub mov calcium fortifiers, stabilizers. Cov tshuaj txhuam hniav qib glycerol calcium phosphate yog siv los ua cov tshuaj txhuam hniav ntxiv hauv kev lag luam tshuaj txhuam hniav vim nws qhov pom tseeb zoo, siab solubility, thiab ceev ceev ceev. Calcium glycerophosphate muaj cov tshuaj tua kab mob thiab tiv thaiv kab mob. Nws tuaj yeem nce cov calcium thiab phosphorus cov ntsiab lus hauv cov hniav enamel, inhibit qhov demineralization ntawm cov hniav enamel, thiab txhim kho cov remineralization ntawm cov hniav enamel. Nws tuaj yeem hloov cov acidity thiab alkalinity ntawm cov hniav enamel nto thiab txhim kho nws cov kua qaub. Cov pH ntawm glycerol calcium phosphate siv los ua cov tshuaj txhuam hniav yog 1.7ml / g ntawm ib qho concentration. Nyob rau tib lub sijhawm, txhawm rau kom tsis txhob cuam tshuam rau qhov zoo ntawm cov tshuaj txhuam hniav, qhov tseeb ntawm calcium phosphate yuav tsum muaj tsawg kawg yog me ntsis turbid. Cov txheej txheem ntawm neutralizing calcium hydroxide thiab glycerol phosphate yog siv, thiab los ntawm ethanol extraction, calcium glycerophosphate ua tau raws li qhov yuav tsum tau ntawm 1.7ml / g, calcium glycerophosphate cov ntsiab lus yog 80%, thiab cov clarity ncav cuag cov ntshiab tshuaj txhuam hniav qib calcium glycerophosphate.
Lub luag haujlwm ntawm calcium glycerophosphate nyob rau hauv cov tshuaj txhuam hniav yog qhov tseem ceeb hauv cov hauv qab no: ① Tswj cov quav hniav. ② Cov nyhuv tiv thaiv ntawm dentin. ③ Kev cuam tshuam ntawm ecological tshuav nyiaj li cas ntawm qhov ncauj flora. Tsis tas li ntawd, calcium glycerophosphate tuaj yeem txhim kho kev nqus ntawm fluoride. Ntxiv {{0}}.1% mus rau 0.13% calcium glycerophosphate rau cov tshuaj txhuam hniav uas muaj SMFP tuaj yeem ua rau muaj kev nqus ntawm cov tshuaj fluoride los ntawm enamel thiab ntxiv dag zog rau fluorination nyhuv ntawm enamel tiv thaiv demineralization.
Calcium glycerophosphate yog cov tshuaj txhuam hniav zoo tshaj plaws rau kev tiv thaiv cov hniav caries thiab kho gingivitis thiab kab mob periodontal. Vim nws txoj kev tiv thaiv zoo hauv cov tshuaj txhuam hniav, calcium glycerophosphate tau txais kev pom zoo los ntawm feem ntau ntawm cov tuam txhab tshuaj txhuam hniav. Txawv teb chaws, xws li Unilever, thiab lwm yam, txhua tus tsim cov tshuaj txhuam hniav glycerol calcium phosphate. Cov khoom lag luam tshiab hauv lub tebchaws nyob hauv Suav teb, xws li Naisi, Oqili, thiab lwm yam, muaj kev cia siab txog kev lag luam ntawm cov khoom muaj nqis ntxiv glycerol calcium phosphate tshuaj txhuam hniav. Tam sim no, muaj cov tshuaj txhuam hniav me me glycerol calcium phosphate. Kev tsim cov tshuaj txhuam hniav calcium phosphate. Raws li kev tshawb fawb, kev lag luam xws li Tebchaws Meskas, Nyiv, Tebchaws Europe, thiab Asia-Pacific tam sim no tau them nyiaj ntau rau cov khoom siv tshuaj txhuam hniav zoo, thiab muaj kev txhawj xeeb ntau ntxiv txog cov khoom xyaw hauv cov tshuaj txhuam hniav. Tag nrho cov no qhia tias kev ua lag luam rau glycerol calcium phosphate tshuaj txhuam hniav muaj qhov dav dav rau kev loj hlob. Tsis tas li ntawd, calcium glycerophosphate kuj tseem siv tau rau hauv qhov ncauj.
Synthesis ntawm calcium glycerophosphate
Tam sim no, cov txheej txheem tseem ceeb ntawm kev npaj glycerol calcium phosphate suav nrog phosphoric acid txoj kev, phosphate ntsev txoj kev, phosphorus oxychloride txoj kev, roj dripping txoj kev, thiab lwm yam. Cov txheej txheem ntawm cov txheej txheem no kuj nyuaj, thiab cov txheej txheem purification ntawm lub hom phiaj khoom calcium glycerophosphate yog. cumbersome thiab nyuaj rau tswj. Calcium glycerophosphate yog tau los ntawm neutralizing calcium hydroxide thiab glycerophosphate los ntawm ethanol extraction kom tsis txhob muaj cov txheej txheem purification ntawm calcium glycerophosphate.
Cov ntsiab lus tsom xam ntawm calcium glycerophosphate
Ua kom raug hnyav txog 2g ntawm cov qauv uas tau qhuav ntawm 150 degree rau 4 teev, thiab yaj hauv 1{{10}}}0ml dej thiab 5ml ntawm dilute hydrochloric acid test tov. Hloov cov tshuaj no rau hauv 250ml volumetric hwj, nqa mus rau ntim nrog dej thiab co zoo. Pipette 50.0ml ntawm cov tshuaj no rau hauv lub thawv tsim nyog thiab ntxiv 50ml dej. Nyob rau hauv nplawm (zoo dua nrog cov hlau nplaum sib nqus), ntxiv txog 30ml ntawm 0.05mol / LEDTA disodium dropwise los ntawm burette, tom qab ntawd ntxiv 15ml ntawm sodium hydroxide test tov thiab 300mg ntawm hydroxynaphthol xiav qhia, thiab tom qab ntawd txuas ntxiv mus ntxiv rau qhov kawg xiav. taw tes. . Txhua ml ntawm 0.05 mol / L disodium EDTA yog sib npaug rau 10.51 mg ntawm calcium glycerophosphate (C3H7CaO6P).
Daim ntawv thov thiab kev cia siab ntawm calcium glycerophosphate
Calcium glycerophosphate yog dav siv hauv tshuaj, zaub mov, tshuaj txhuam hniav thiab lwm yam lag luam. Nws tuaj yeem siv los ua calcium ntxiv hauv cov khoom noj; Nyob rau hauv cov tshuaj, nws plays lub lom thiab physiological zog ntawm calcium, muaj nuj nqi ntawm kev txhim kho cov ntaub so ntswg hlwb thiab tsim cov pob txha cov ntaub so ntswg, thiab nyob rau tib lub sij hawm plays lub luag hauj lwm ntawm calcium glycerophosphate metabolism, thiab muaj nuj nqi ntawm supplementing calcium. Lub luag hauj lwm ntawm lub hlwb vitality. Thaum ntxov li xyoo 1960, calcium glycerophosphate tau pom tias muaj cov kab mob tua kab mob thiab tiv thaiv kab mob. Los ntawm kev tshawb fawb, nws tau pom tias nws tuaj yeem nce cov calcium thiab phosphorus cov ntsiab lus hauv cov hniav enamel, inhibit qhov demineralization ntawm cov hniav enamel, thiab txhim kho cov remineralization ntawm cov hniav enamel. Calcium glycerophosphate tuaj yeem hloov cov acidity thiab alkalinity ntawm cov hniav enamel thiab txhim kho nws cov kua qaub. Qhov zoo ntawm calcium glycerophosphate yog qhov tseeb ntawm nws tus kheej, tab sis tam sim no nws tsis tau siv dav hauv kuv lub teb chaws cov khoom lag luam kho qhov ncauj. Calcium glycerophosphate yog ib qho khoom siv zoo tshaj plaws rau cov khoom siv hauv qhov ncauj, tshwj xeeb tshaj yog haum rau calcium ntxiv cov tshuaj txhuam hniav thiab zom cov pos hniav. Nws kuj yog ib qho tshuaj tiv thaiv kab mob. Ib qho khoom siv zoo tshaj plaws rau cov khoom siv ntxiv, nws tuaj yeem siv rau hauv cov menyuam yaus cov tshuaj txhuam hniav los txhawb cov hniav loj hlob thiab ntxiv dag zog rau calcium. Los ntawm cov qauv kev sim ntawm ntau yam khoom, qhov sib ntxiv ntawm calcium glycerol phosphate, them sai sai rau cov yam ntxwv ntawm calcium glycerol phosphate, tsis muaj qhov sib txawv hauv kev ruaj ntseg thiab lwm yam kev ntsuas zoo ntawm feem ntau cov khoom tu qhov ncauj piv nrog cov tsis muaj ntxiv, thiab tuaj yeem muab tag nrho ua si rau cov khoom ntawm calcium glycerol phosphate. Calcium muaj peev xwm tiv thaiv kab mob caries, acid thiab remineralize cov hniav, yog li nws yuav tsum ua lub luag haujlwm ntau dua hauv daim teb no.
