Okuqukethwe
I-Orthophosphoric acid (i-Phosphoric acid, i-orthophosphoric acid, i-E338)
I-Orthophosphoric (phosphoric) acid iyinhlanganisela evela esigabeni se-inorganic, i-asidi ebuthakathaka. Esigabeni esamukelekayo sezithasiselo zokudla, i-orthophosphoric acid inekhodi E338, ingeyeqembu lama-antioxidants (ama-antioxidants), futhi isetshenziswa njengesilawuli se-acidity.
Ifomula yekhemikhali H3PO4. Emazingeni okushisa angaphezu kuka-213 °C, iguqulwa ibe yi-pyrophosphoric acid H4P2O7. Incibilika kahle kakhulu emanzini.
Izici ezijwayelekile ze-E338
I-Orthophosphoric acid inezakhiwo zomzimba ezilandelayo - into e-crystalline engenambala nephunga, inyibilika kahle emanzini okuncibilikisa, evame ukusetshenziswa ngendlela yoketshezi olune-syrupy (85% isixazululo samanzi se-orthophosphoric acid). I-Orthophosphoric acid itholakala ngamakhemikhali ku-phosphate noma nge-hydrolysis (i-calorizator). I-Orthophosphoric acid ibonakala ngezindleko eziphansi (uma iqhathaniswa, isibonelo, ne-citric acid), ngakho-ke isetshenziswa kaningi ekukhiqizeni ukudla neziphuzo.
Ukulimala kwe-Orthophosphoric acid
Umphumela omubi oyinhloko we-E338 emzimbeni womuntu ukwandisa i-asidi, ngaleyo ndlela iphazamise ibhalansi ye-acid-base, ngakho-ke imikhiqizo equkethe i-E338 kufanele isetshenziswe ngokuqapha okukhulu kubantu abanesifo sofuba esine-acidity ephezulu, ngokufanelekile-ukubakhipha ekudleni. . Ngokusho kodokotela, i-Orthophosphoric acid inendawo yokukhipha i-calcium emzimbeni, enomthelela omubi kakhulu esimweni sezinyo koqweqwe lwawo kanye nezicubu zethambo, okubangela i-caries kanye ne-osteoporosis. Ukusetshenziswa ngokweqile kwe-E338 kubangela ukuphazamiseka kwamathumbu, isicanucanu nokuhlanza.
Ukusetshenziswa kwe-E338
Njengomlawuli we-asidi, i-Orthophosphoric acid isetshenziswa embonini yokudla ukunikeza imikhiqizo ukunambitheka okumuncu noma okubaba kancane. Isetshenziselwa ukukhiqizwa kweziphuzo ezithambile ze-carbonated, ushizi ocutshungulwayo, ezinye izinhlobo zemikhiqizo ye-sausage kanye ne-baking powder.
Okunye ukusetshenziswa kwe-Orthophosphoric acid: amazinyo, i-cosmetology, izindiza zezindiza kanye nezimboni zemithi, ukukhiqizwa kwezinto zokuhlanza kanye neziguquli zokugqwala. Kwezolimo, i-Orthophosphoric acid iyingxenye yezinhlobo eziningi zomanyolo.
Ukusetshenziswa kwe-E338
Ensimini yezwe lethu, ukusetshenziswa kwe-Orthophosphoric acid kuvunyelwe, ukuhambisana nezindinganiso eziphezulu ezivunyelwe ukusetshenziswa kuyimpoqo.
