Lithium Bromide (LiBr)
ʻO Lithium Bromide (LiBr), kahi hui hygroscopic i haku ʻia me ka lithium a me ka bromine, hoʻohana nui ʻia i nā noi ʻoihana a me nā kemika ma muli o kona mau waiwai physicochemical kū hoʻokahi. Hoʻohui ʻia ia ma o nā hopena e like me ka mālama ʻana i ka lithium carbonate me ka waikawa hydrobromic a i ʻole ka hana ʻana i ka lithium hydroxide me ka bromine, e loaʻa ana nā hydrates crystalline i ʻokoʻa mai nā bromides alkali metal ʻē aʻe.
Hōʻike ʻo LiBr i ka solubility kūikawā i ka wai, ka waiʻona, a me ka ether, me nā hopena wai i hoʻopaʻa ʻia e hōʻike ana i nā kaomi wai haʻahaʻa. ʻO kēia waiwai, i hui pū ʻia me kona hygroscopicity kiʻekiʻe, e lilo ia i mea desiccant maikaʻi a me ka sorbent wai, ʻoi aku hoʻi i nā ʻōnaehana refrigeration absorption a me nā ea-conditioning. Eia kekahi, ʻo kona hiki ke hoʻoheheʻe i nā hui organik polar e like me ka cellulose e hoʻonui i kona pono i nā kaʻina hana kemika kūikawā, me ka catalytic dehydrohalogenation no ka olefin synthesis.
I nā noi mālama wai a me ka ulu ʻana o ke kristal, he mea maikaʻi ka solubility o LiBr a me nā ʻano maʻemaʻe ultra-kiʻekiʻe (submicron/nanopowders). Hiki ke ʻike ʻia ka ion bromide i loko o nā hopena wai me ka hoʻohana ʻana i ka carbon disulfide a me ka chlorine. Eia nō naʻe, pono ke akahele i ka lawelawe ʻana: hoʻopuka ʻo LiBr i ka wela nui i ka wā e hoʻoheheʻe ʻia ai (ma muli o ka enthalpy maikaʻi ʻole o ka hopena) a hōʻike i nā pōʻino ma ke ʻano he mea ʻino iki a me ka psychoactive.
Hāʻawi ʻo UrbanMines iā LiBr i nā ʻano like ʻole (Mil Spec, ACS, Pharmaceutical, a me nā mea ʻē aʻe), nā koho hoʻopili, a me nā purities, e pili ana i nā kūlana ASTM, USP, a me EP/BP. Hāʻawi ʻia ke kākoʻo loea, ka ʻikepili palekana (MSDS), a me nā mea hana hoʻololi ʻāpana e hōʻoia i ka palekana a me ka hoʻomaikaʻi ʻia ʻana o ka noi ma nā ʻoihana.

He aha ka mea e hoʻohana ʻia ai ka Lithium Bromide (LiBr)?
Lithium Bromide (LiBr)- Nā noi a me nā hoʻohana
ʻO Lithium Bromide (LiBr) kahi paʻakai inorganic hiki ke hoʻoheheʻe ʻia a hygroscopic me nā waiwai thermodynamic a me nā kemika kū hoʻokahi. He mea koʻikoʻi ia i ka hoʻoluʻu ikehu nui a lawelawe ma ke ʻano he reagent versatile i ka synthesis kemika holomua. ʻO kā mākou Lithium Bromide maʻemaʻe kiʻekiʻe, i loaʻa i nā ʻano hopena wai paʻa a me ka hoʻohuihui ʻia, ua hana ʻia no ka hilinaʻi a me ka hana ma waena o kāna mau noi like ʻole.
Nā Hana a me nā ʻOihana Mua:
1. Ka Mana Ikehu a me ke Kaiapuni
ʻO ka hoʻohana koʻikoʻi o ka Lithium Bromide ʻo ia ka hoʻokele wela, kahi e hiki ai ke hoʻoluʻu maikaʻi a hoʻomau.
* Hoʻomaʻalili ʻana i ka ʻōpū: ʻO kahi hopena wai 50-60% o LiBr ka wai hana maʻamau i nā mea hoʻomaʻalili ʻōpū nui. Hoʻohana kēia mau ʻōnaehana i ka wela (mai ka mahu ʻōpala, ka wela o ka lā, a i ʻole ke kinoea kūlohelohe) ma kahi o ka mana uila nui e hoʻokele i ke kaʻina hana hoʻomaʻalili, e hāʻawi ana i kahi hopena ikehu-mālama no:
* Nā ʻōnaehana hoʻoluʻu ʻāpana
* Hoʻomaʻalili ʻana i ke kaʻina hana ʻoihana
* Nā ʻōnaehana HVAC kālepa nui
2. Hana Kemika a me ka Hana ʻana
I loko o nā ʻoihana kemika a me nā lāʻau lapaʻau, ua manaʻo ʻia ʻo LiBr paʻa ma ke ʻano he reagent ikaika a maʻalahi hoʻi.
* Lewis Acid Catalyst: Hoʻomaʻalahi i nā ʻano hoʻololi organik, me ka oxidation, hydroformylation, a me nā hopena cyclization, ma muli o kona hiki ke hoʻonohonoho pū me nā hui hana organik.
* Mea Hoʻolaha Hana: Hoʻohana ʻia i nā ʻanuʻu deprotonation a me ka dehydration no nā hui waikawa koʻikoʻi, e hiki ai ke hana ʻia nā ʻano molekala paʻakikī.
* Mea Hoʻomaʻemaʻe: Kōkua i ka hoʻomaʻemaʻe ʻana o nā molekala organik paʻakikī, e like me nā steroids a me nā prostaglandins, i ka wā e hana ʻia ai.
3. Nā ʻEpekema Lāʻau Lapaʻau a me ke Ola
ʻOiai ua emi iho kona hoʻohana ʻana i nā lāʻau lapaʻau, ua lilo ʻo LiBr i mea hana waiwai nui i ka hana ʻana i nā lāʻau lapaʻau.
* Kemika Waena: Ke komo nei i ka hana ʻana o nā mea hana lāʻau lapaʻau ikaika (APIs).
* Mea Hoʻomaloʻo: Hoʻohana ʻia kona hygroscopicity kiʻekiʻe loa e kāohi i ka makū i nā kaʻina hana kikoʻī.
* Hoʻohana Mōʻaukala: Ua hoʻohana mua ʻia ma ke ʻano he lāʻau hoʻomaha a no nā kūlana e like me ka maʻi bipolar, ua pani nui ʻia kāna hoʻohana lāʻau lapaʻau e nā lāʻau lapaʻau ʻoi aku ka palekana a me nā lāʻau hou.
4. Nā Noi Hana Kūikawā
* ʻEnehana Kiʻi: ʻO kona solubility kiʻekiʻe i nā mea hoʻoheheʻe organik e like me ka waiʻona a me ka ether i hoʻolilo iā ia i mea nui i ka hoʻokumu ʻana o nā emulsions pā maloʻo collodion i ke kiʻi paʻi kiʻi kuʻuna.
* Ka Mana Hoʻomaʻū: Hoʻohana ʻia i nā ʻōnaehana hoʻomaloʻo ea ʻoihana kūikawā kahi e pono ai ka omo ʻana o ka makū pololei.
* Noiʻi a me ka ʻEpekema Mea: Hoʻohana ʻia i ka ulu ʻana o ke kristal a me nā kaʻina hana hoʻokolohua niche ʻē aʻe e hoʻohana ana i kona mau waiwai ionic paʻa.

Nā ʻano koʻikoʻi a me nā pono:
* Hygroscopicity kūikawā: Loaʻa ka pono i ka omo ʻana i ka mahu wai, e kūpono ai no ka hoʻomaʻalili ʻana a me ka hoʻomaloʻo ʻana.
* Ka Hoʻoheheʻe Kiʻekiʻe: Hōʻike i ka solubility maikaʻi loa i ka wai a me nā mea hoʻoheheʻe organik polar, e hāʻawi ana i ka maʻalahi o ka hoʻohui ʻana.
* Ke kūpaʻa Thermodynamic: Hāʻawi i ka hana hilinaʻi i nā kūlana ʻoihana koi, e like me nā mea hoʻoluʻu omo wela kiʻekiʻe.
* Mea Hoʻohui Kūikawā: Hana ma ke ʻano he mea hoʻoulu, mea hoʻolaha, a me ka mea hoʻomaʻemaʻe i ka hana kemika paʻakikī.
ʻŌlelo Hoʻolaha: Pono e mālama pono ʻia ka Lithium Bromide, no ka mea, hiki i nā hopena i hoʻopaʻa ʻia ke ʻino. ʻO ke kuleana o ka mea hoʻohana ke hōʻoia i nā hana lawelawe palekana a e hoʻoholo i ke kūpono o ka huahana no kā lākou noi kikoʻī e like me nā lula pili āpau.
