Maikaʻi ke kūʻai aku i ka meaʻai meaʻai ʻona Citric Acid Monohydrate CAS77-92-9
Nā kikoʻī huahana
MF: C6H10O8
MW: 210.1388
CAS: 5949-29-1
ʻO 1.Citric acid monohydrate he aniani kala ʻole a i ʻole ka pauka crystalline keʻokeʻo, me ka nui o 1.54.Ka helu hehee 135-152 ℃.ʻO ke kiko uila 173.9 ℃.Hiki ke hoʻoheheʻe ʻia i ka wai 1630 g/l (20 ℃).
2.Colorless kristal a keʻokeʻo crystalline pauka.
3.White crystalline pauka, hiki ke hoʻoheheʻe ʻia i ka methanol a me ka wai, mai ka plum ʻeleʻele, ka ʻalani ʻono a me ka wai lemon.
4.Hoʻopuka nuiʻia kēia huahana e ka fermentation.Hiki i kāna mau mea maka ke lilo i kaʻaleʻa e like me ka molasses, sucrose, ʻuala a me ka petroleum hydrocarbons.ʻO ka maʻamau, hoʻohana ʻia nā fungi no ka fermentation.Wahi a ke ʻano fermentation, hiki ke hoʻokaʻawale ʻia i ka fermentation o ka honua a me ka fermentation hohonu.ʻO ka fermentation o ka ʻili he ala hana mua, me ka hoʻohana ʻana i kekahi Penicillium a i ʻole Aspergillus niger e like me nā kānana;Ma ke ʻano o ka fermentation submerged, hoʻohana ʻia ʻo Aspergillus niger ma ke ʻano he kānana.I ka wā o ka fermentation, hana ʻia kahi pōpō liʻiliʻi o ka mycelium polymer me ka puke kemika.Pono e pale i ka ulu a me ka mycelium lahilahi.ʻO ke kūlana fermentation ʻo ka pH waiwai he 1.5 ~ 2.8.I ka manawa like, pono e hoʻokomo a hoʻoulu ʻia ka ea sterile.Ma hope o ka fermentation, pono e kānana ʻia ka mycelium a me ke koena o ka ʻōpala paʻa.Hoʻopili ʻia ka filtrate me ka calcium carbonate e loaʻa ai ka calcium citrate, a laila hoʻokaʻawale ʻia me ka sulfuric acid concentrated e loaʻa ai ka waikawa citric crude, Hoʻomaʻamaʻa ʻia ka huahana i hoʻopau ʻia, hoʻopaʻa ʻia a crystallized e ka resin exchange ion.
Palapala noi
Hoʻohana nui ʻia ka 1.Citric acid monohydrate i ka ʻoihana meaʻai a me ka mea inu e like me ka mea ʻawaʻawa, ka mea hoʻonaninani, ka mālama a me ka mālama.Hoʻohana ʻia ʻo ia e like me ka antioxidant, plasticizer a me ka mea holoi ma ka ʻoihana kemika, ʻoihana hoʻonaninani a me ka ʻoihana holoi.
2. Hoʻohana nui ʻia ʻo ia ma ke ʻano he mea ʻawaʻawa no ka meaʻai, a hoʻohana ʻia hoʻi e hoʻomākaukau i nā mea hoʻomaʻamaʻa lāʻau lapaʻau, nā mea hoʻohui detergent, etc.
3. Eʻike i ka bismuth, nitrite, oxygen a me ka wai, e hoʻoholo i ka aluminika, ke keleawe, ka mercury, ka nickel, ka oxygen a me ka thorium, e hoʻohana ma ke ʻano he multivalent chelating agent, wehe i nā metala, hoʻomākaukau i ka hopena buffer, a hoʻoholo i ka potassium koko.
