Iyo yechinyakare nzira yekugadzira inositol ndeyekumanikidza hydrolysis. Nekuda kwemakore ehunyanzvi hwekugadzira maindasitiri, iyo yekumanikidza hydrolysis nzira ndiyo huru tekinoroji tekinoroji inogamuchirwa nevagadziri vepamba uye yakaramba ichivandudzwa mukugadzira. Nzira yakawanda yekumanikidza hydrolysis nzira ndeyotevera: phytin (hydrolysis) → hydrolysis solution (neutralization, filtration) → inositol mhinduro (kusvibiswa kubviswa uye kuisa pfungwa, crystallization centrifugation) → crude inositol (kuparara uye kusvibiswa kubviswa, crystallization centrifugation) → chigadzirwa chakanaka. Pakati pavo, hydrolysis uye kunatsa ndiwo maviri akakosha matanho.
Sodium phytate hydrolysis
Uchishandisa chibage chakanyoroveswa mvura seyakabikwa, sodium phytate inogadzirwa neion exchange resin adsorption nzira, uye yobva yaiswa pasi pekumanikidzwa hydrolysis reaction kuti ibudise inositol. Panguva imwe chete yekugadzira inositol, kugadzirwa kwe disodium hydrogen phosphate (kugadzirwa kwe disodium hydrogen phosphate kanenge ka12 kune inositol) zvinobudirira kudzoreredza organic phosphorus kubva muzviyo, kuvhura nzira nyowani yekudzoreredza organic phosphorus mune zvekurima uye parutivi zvigadzirwa.
Tsanangudzo yemaitiro ekugadzira: Chibage ichinyura mvura inoshambadzwa neion exchange resin kuti iwane imwe denderedzwa yesodium phytate solution, iyo inoiswa pasi pekumanikidzwa hydrolysis reaction kuti ibudise inositol uye disodium hydrogen phosphate. Mushure meimwe nguva yekuita, zvinhu zvacho zvinoburitswa, kusefa, kutonhodzwa, uye kukwenenzverwa, zvichikonzera kunaya kwe disodium hydrogen phosphate makristasi. Iyo hydrolysis reaction solution yesodium dihydrogen phosphate makristasi inonatswa zvakatevedzana kuburikidza neanion uye cation exchange resin kudzamara kusungirirwa kweanioni uye cations muiyo hydrolysis reaction mhinduro yasvika pane yakatarwa chiyero. Iyo yakanatswa hydrolysis reaction solution inogona kuisirwa uye kukwenenzverwa kuti iwane yakapedzwa chigadzirwa inositol. Goho reinositol rinonyanya kukanganiswa nezvinhu zvitatu: hydrolysis reaction time, hydrolysis reaction pressure, uye concentration ye sodium phytate solution. Kuburikidza nemiedzo ye orthogonal, maitiro ekugadzirisa maitiro e hydrolysis reaction akawanikwa sezvinotevera: nguva ye hydrolysis yemaawa 7-8, kusungirirwa kwe sodium phytate ye20%, hydrolysis pressure ye 1.5 MPa, uye muvhareji weinositol kubva 0.1544% kusvika 0.1722%. Kuti utarise kukwidziridzwa kweiyo hydrolysis reactor, kuvharika kwemubhedha muindasitiri ion yekutsinhana shongwe, shanduko mukutsinhana simba, uye kutevedzera yakakura kutenderera mamiriro ekushanda anoshandiswa muchikamu chekuvandudzwa kwemidziyo yemaindasitiri, bvunzo yekutyaira yakaitwa pamudziyo une simba rekugadzirisa re600m/a pasi pemamiriro ekuita ari pamusoro. Ivhareji yegoho yeinositol ndeye 0.1601% (inopfuura 2.5 nguva yakakwirira kudarika nzira ye calcium phytate, uye unhu hwechigadzirwa hunosangana nezviratidzo zvakasiyana-siyana zvinotsanangurwa muNational Pharmacopoeia), iyo inopindirana nediki-diki rekuongorora data.
Atmospheric pressure catalytic nzira
The atmospheric pressure catalytic method inzira itsva yekugadzira inositol iyo ichangobva kugadzirwa uye kuiswa mukugadzirwa kwemaindasitiri muChina mumakore achangopfuura. Yayo hydrolysis uye kunatswa kune akasiyana maitiro. Zvinokosha:
(1) Zvinonyanya kuderedza iyo imwe-nguva yekudyara mumidziyo, uye inogona kuchengetedza inopfuura 50% yemidziyo yekudyara kana chiyero chakafanana;
(2) Kushandiswa kwephytin hydrolysis catalyst kunopfupisa kutenderera kwekugadzira uye kunatsiridza mwero wekushandiswa kwezvinhu zvakasvibirira;
(3) Nzira yekuchenesa yakagadziridzwa, zvichiita kuti kuwedzerwa kwehutano hwechigadzirwa uye goho.
Atmospheric pressure catalytic process: Chimwe chikamu checatalyst (inoumbwa neglycerol, urea, uye calcium carbonate) inowedzerwa kune imwe fungidziro ye phytin solution pamhepo yemhepo, uye inopisa hydrolysis. Mushure me hydrolysis, kusefa, crystallization, kuomesa, uye mamwe maitiro, inositol inogona kuwanikwa. Nekuda kwehunhu hweiyo catalyst, inositol inogona kukwenenzverwa mune imwe kuenda, zvichikonzera mhando yepamusoro yakapedzwa zvigadzirwa uye kurerutsa maitiro. Catalysts inogona kushandiswa zvakare.
