imikhiqizo
Ukuthengiswa Kahle Komkhiqizo Wokudla Ibanga le-Citric Acid Monohydrate CAS77-92-9
Imininingwane yomkhiqizo
MF: C6H10O8
MW: 210.1388
CAS: 5949-29-1
I-1.I-Citric acid monohydrate iyikristalu engenambala noma i-crystalline powder emhlophe, enobuningi be-1.54.Iphoyinti lokuncibilika 135-152 ℃.Iphoyinti le-Flash 173.9 ℃.Amanzi ancibilikayo 1630 g/l (20 ℃).
I-2.I-crystal engenambala noma i-crystalline powder emhlophe.
3.Impushana ecwebezelayo emhlophe, encibilika kalula ku-methanol nasemanzini, kusuka kuplamu emnyama, iwolintshi elimnandi nejusi kalamula.
4.Lo mkhiqizo ukhiqizwa ikakhulukazi ngokuvutshelwa.Izinto zayo ezingavuthiwe zingaba ama-carbohydrate afana ne-molasses, i-sucrose, ubhatata kanye nama-petroleum hydrocarbons.Ngokuvamile, isikhunta sisetshenziselwa ukuvutshelwa.Ngokwemodi yokuvutshelwa, ingahlukaniswa ibe ukuvutshelwa okungaphezulu kanye nokuvutshelwa okujulile.Ukuvutshelwa okungaphezulu kuyindlela yokuqala yokukhiqiza, kusetshenziswa i-Penicillium noma i-Aspergillus niger njengezinhlobo;Endleleni yokuvutshelwa engaphansi kwamanzi, i-Aspergillus niger nayo isetshenziswa njengohlupho.Phakathi nenqubo yokuvutshelwa, kukhiqizwa ibhola elincane le-chemicalbook emise okwe-mycelium polymer.Ukukhula kanye ne-mycelium encane kufanele kugwenywe.Isimo sokuvutshelwa ukuthi inani le-pH lingu-1.5 ~ 2.8.Ngesikhathi esifanayo, umoya oyinyumba kufanele ungeniswe futhi ushukunyiswe.Ngemuva kokuvutshelwa, i-mycelium nemfucumfucu esele esele kufanele ihlungwe.I-filtrate ingathathi hlangothi nge-calcium carbonate ukuze ithole i-calcium citrate, bese ihlukaniswa ne-sulfuric acid egxilile ukuze ithole i-citric acid engahluziwe, Umkhiqizo oqediwe uyacwengwa, ugxiliswe futhi ucwebezeliswe yi-ion exchange resin.
Isicelo
I-1.Citric acid monohydrate isetshenziswa kakhulu embonini yokudla nesiphuzo njenge-agent emuncu, i-seasoning agent, i-preservative kanye ne-preservative.Ibuye isetshenziswe njenge-antioxidant, i-plasticizer kanye ne-detergent embonini yamakhemikhali, imboni yezimonyo kanye nemboni yokuwasha.
I-2.Isetshenziswa kakhulu njenge-ejenti emuncu yokudla, futhi isetshenziselwa ukulungisa izinto zokupholisa imithi, izithasiselo zokuhlanza, njll.
3.Thola i-bismuth, i-nitrite, i-oxygen namanzi, thola i-aluminium, ithusi, i-mercury, i-nickel, i-oxygen ne-thorium, sebenzisa njenge-ejenti ye-multivalent chelating, susa izinsimbi zokulandelela, lungisa isisombululo se-buffer, futhi unqume i-potassium yegazi.
