Kugulitsa Bwino Zinthu Zakudya Gawo la Citric Acid Monohydrate CAS77-92-9
Zambiri zamalonda
MF: C6H10O8
MW: 210.1388
CAS: 5949-29-1
1.Citric asidi monohydrate ndi colorless crystal kapena woyera crystalline ufa, ndi kachulukidwe wa 1.54.Malo osungunuka 135-152 ℃.Flash point 173.9 ℃.Madzi osungunuka 1630 g/l (20 ℃).
2.Colorless crystal kapena woyera crystalline ufa.
3.White crystalline ufa, wosungunuka mosavuta mu methanol ndi madzi, kuchokera ku maula amdima, malalanje okoma ndi madzi a mandimu.
4.This mankhwala makamaka amapangidwa ndi nayonso mphamvu.Zopangira zake zimatha kukhala chakudya chamafuta monga molasi, sucrose, mbatata ndi ma hydrocarbon a petroleum.Nthawi zambiri, bowa amagwiritsidwa ntchito kupesa.Malinga ndi nayonso mphamvu, imatha kugawidwa m'magawo a fermentation ndi kuthirira kwambiri.Kuwotchera pamwamba ndi njira yoyambilira yopangira, pogwiritsa ntchito Penicillium kapena Aspergillus niger ngati mitundu;Mu njira yowira pansi pamadzi, Aspergillus niger amagwiritsidwanso ntchito ngati kupsyinjika.Panthawi yowotchera, mpira wawung'ono wa polymer wopangidwa ndi chemicalbook wopangidwa ndi mycelium umapangidwa.Kukula ndi kuonda kwa mycelium kuyenera kupewedwa.Vuto la fermentation ndikuti pH mtengo ndi 1.5 ~ 2.8.Pa nthawi yomweyi, mpweya wosabala uyenera kuyambitsidwa ndikugwedezeka.Pambuyo pake, mycelium ndi zinyalala zotsalira ziyenera kusefedwa.The filtrate ndi neutralized ndi calcium carbonate kupeza kashiamu citrate, ndiyeno neutralized ndi concentrated sulfuric acid kupeza yaiwisi citric acid, Chomalizidwa ndi woyengedwa, moyikirapo ndi crystallized ndi ion kuwombola utomoni.
Kugwiritsa ntchito
1.Citric asidi monohydrate zimagwiritsa ntchito mu makampani chakudya ndi chakumwa monga wowawasa wothandizira, zokometsera wothandizila, preservative ndi preservative.Amagwiritsidwanso ntchito ngati antioxidant, plasticizer ndi detergent mumakampani opanga mankhwala, zodzoladzola ndi mafakitale ochapira.
2.Amagwiritsidwa ntchito makamaka ngati wowawasa chakudya, komanso amagwiritsidwa ntchito pokonzekera mankhwala ozizira ozizira, detergent zowonjezera, etc.
3.Detect bismuth, nitrite, oxygen ndi madzi, dziwani aluminium, mkuwa, mercury, nickel, oxygen ndi thorium, gwiritsani ntchito monga multivalent chelating agent, chotsani zitsulo, konzekerani yankho la buffer, ndi kudziwa potaziyamu yamagazi.
