Alli phosphate

Tribasic phosphoric acid siffofin da iri uku na alli salts. Wannan alli hydrogen phosphate CaHPO4, alli dihydrogen phosphate Ca (H2PO4) 2 da kuma orthophosphate, ko alli phosphate, wanda dabara aka bai da: Ca3 (PO4) 2. Wannan gishiri ne inorganic abu, a karkashin tuta yanayi ne mai ɗamfarar, da kuma cikin ruwa kafa (melts) a zazzabi na 1200 C. The yawa daidai 2,81 g / cm³, da matauni taro - 310,2 g / mole. Alli phosphate ne talauci mai narkewa a cikin ruwa: a 20 ° C da taro sulusi da murabba'i na shi ba ya wuce 0,0025%. Ba kamar mafi sauran mahadi, matakin da solubility rage-rage tare da kara yawan zafin jiki. Saboda haka, a cikin dumama wannan gishiri ne iya samar da adibas.

Alli phosphate ne wani farin crystalline abu, wanda shi ne bangare na ma'adinai apatite (nasa ne da aji na phosphates dauke da har zuwa 56% Cao, game da 41% P2O5), phosphorite (fibrous ko m aggregates na apatite dauke da fiye da 18% P2O5) da kuma hydroxyapatite (main bangaren na mutane da dabbobi kashi). Mun tabbatar da asalin wasu adibas na tumbi ko matattu dabbobi. Sauran filayen (misali, a zamanin d tekuna) kafa a sakamakon rayuwa "fosforobaktery". Amma a wasu wurare, adibas na wannan ma'adinai ne zalla ma'adinai asalin. Dukan su suna yadu rarraba a cikin yanayi da ake amfani da su a cikin kasa da tattalin arziki.

Apatite ne a albarkatun kasa domin phosphorus, phosphate taki da kuma phosphoric acid, kazalika da amfani a ferrous da nonferrous metallurgy a samar da gilashin da yumbu. Halitta ma'adanai ne phosphate kankara na daban-daban asalin, amma mafi sedimentary, suna amfani da shi don kara enrichment da kuma samar da sinadarin phosphate takin. Hannun jari phosphorites da apatites ne na mai da muhimmanci ga aikin gona, tun ba kawai amfani da samar da takin, amma kuma a matsayin alli source for ciyar da tsuntsaye, ko dabbobi: fodder alli phosphate samar daidai da Gost 23999-80.

Ma'adinai inorganic - apatite - da ake amfani a fiye da ashirin masana'antu tafiyar matakai. Its amfani a samar da abrasives, gilashin da tukwane, kazalika don samar da free phosphoric acid da phosphorus. A tsari Saide bisa ga makirci: 3SiO2 + Ca3 (PO4) 2 + 5C → 3CaSiO3 + 5CO + 2P. Wannan abu ne ma da'awa a masana'antun sarrafa kayayyakin abinci: samuwa a matsayin abinci ƙari E341 bisa ga Gost P 53945-2010, inda, tare da 1- da 2-sauya salts na phosphoric acid hada da alli phosphate. A shirye-shiryen da wannan samfurin ya shafi stringent bukatun ga feedstock. A samar da abinci Additives amfani acid phosphoric sa A daidai da Gost 10678-76, alli hydroxide bisa ga Gost 9262-77 kuma chemically precipitated alli bisa ga Gost 8253-79.

Ma'adinai dauke da alli phosphate, taka muhimmiyar rawa a cikin jikin mutum. Hydroxyapatite za a iya wakilta da dabara 3Sa3 (PO4) 3 • Ca (OH) 2. Shi ne babban bangaren na ginin abu da kuma adam kashi. Wannan ma'adinai ɓangare na enamel a cikin hanyar fluorapatite. A kullum da ake bukata domin manyan da phosphorus ne a cikin kewayon daga 800 zuwa 1500 MG. A lokacin metabolism na phosphorus da mahadi a jikin mutum amsa hanta da kuma tsara wannan tsari hormones da kuma bitamin D. cututtuka daban-daban na kashi da hakora ɓullo da tare da wani rashi na phosphorus a cikin jiki. alli phosphate zo daga abinci, Qarfafa hakora da ƙashi, da kuma a hade tare da wasu ma'adanai goyon bayan zuciya da jijiyoyin jini tsarin, ya hana ciwon daji ta hanji, tsara jijiya aiki, da hannu a cikin shiri na collagen, na taimaka wa ƙananan cholesterol. A phosphates aka samu daga tumbi, da kuma fitsari kullum saki game 4 g na phosphoric acid salts.

Babban kafofin alli phosphate to mutum - saniya ta madara da kuma kiwo kayayyakin, da hatsi, masu garu juices, cuku, goat ta madara, kifi, sardines da kuma anchovies. Da yake talauci mai narkewa a cikin ruwa shi ne alli phosphate a wani babban taro a madara, tun akwai wani colloidal tsarin a cikin nau'i na micelles - barbashi sosai kananan insoluble core, wanda aka kewaye da sauran ƙarfi da kwayoyin da adsorbed ions. Kunshe a cikin madara casein, mafi daidai, alli caseinate, wadda ke da alaka phosphoproteins, tun da shi ya ƙunshi wani phosphate kungiyar. Duk da haka, masana bayar da shawarar don kauce wa wani wuce haddi na alli phosphate, musamman a cikin irin garu abinci da kari, idan wani mutum yana da ko dai daga cikin wadannan cututtuka: parathyroid, koda duwatsu ko a lokacin gudana magani hada da tetracycline maganin rigakafi.
