Lithium Bromide (LiBr)
Lithium Bromide (LiBr), motsoako o nang le hygroscopic o entsoeng ka lithium le bromine, o sebelisoa haholo lits'ebetsong tsa indasteri le lik'hemik'hale ka lebaka la thepa ea eona e ikhethang ea fisik'hemik'hale. E hlahisoa ka liketso tse kang ho phekola lithium carbonate ka hydrobromic acid kapa ho arabela lithium hydroxide ka bromine, ho hlahisa li-hydrate tse kristale tse fapaneng le li-bromide tse ling tsa tšepe ea alkali.
LiBr e na le ho qhibiliha ho ikhethang metsing, joala le ether, ka litharollo tse matla tsa metsi tse bonts'ang khatello e tlase ea mouoane oa metsi. Thepa ena, hammoho le hygroscopicity ea eona e phahameng, e etsa hore e be desiccant e sebetsang hantle le sorbent ea metsi, haholo-holo lits'ebetsong tsa ho monya le tsa ho pholisa moea. Ho feta moo, bokhoni ba eona ba ho qhala metsoako ea tlhaho ea polar joalo ka cellulose bo atolosa thuso ea eona lits'ebetsong tse ikhethileng tsa lik'hemik'hale, ho kenyeletsoa le catalytic dehydrohalogenation bakeng sa tlhahiso ea olefin.
Litšebelisong tsa kalafo ea metsi le kholo ea kristale, ho qhibiliha ha LiBr le mefuta ea bohloeki bo phahameng haholo (submicron/nanopowders) li molemo. Ion ea bromide e ka fumanoa litharollong tsa metsi ho sebelisoa carbon disulfide le chlorine. Leha ho le joalo, ho sebetsana le eona ho hloka tlhokomelo: LiBr e hlahisa mocheso o moholo ha e qhibiliha (ka lebaka la enthalpy e mpe ea tharollo) 'me e baka likotsi e le ntho e senyang hanyane le e amang kelello.
UrbanMines e fana ka LiBr ka mefuta e fapaneng (Mil Spec, ACS, Pharmaceutical, jj.), dikgetho tsa ho paka, le bohloeki, ho latela maemo a ASTM, USP, le EP/BP. Tshehetso ya tekheniki, data ya polokeho (MSDS), le disebediswa tsa phetoho ya yuniti di a fanwa ho netefatsa tshebediso e bolokehileng le e ntlafaditsweng ho pholletsa le diindasteri.

Lithium Bromide (LiBr)- Likopo le Litšebeliso
Lithium Bromide (LiBr) ke letsoai le sa pheleng le qhibilihang haholo le nang le thepa e ikhethang ea thermodynamic le ea lik'hemik'hale. Ke thepa ea bohlokoa pholisong e bolokang matla ka bongata 'me e sebetsa e le reagent e feto-fetohang tlhahisong e tsoetseng pele ea lik'hemik'hale. Lithium Bromide ea rona e hloekileng haholo, e fumanehang ka mefuta ea tharollo ea metsi e tiileng le e kopaneng, e entsoe bakeng sa ts'epo le ts'ebetso lits'ebetsong tsa eona tse fapaneng.
Likopo tsa mantlha le Liindasteri:
1. Taolo ea Matla le Tikoloho
Tšebeliso ea bohlokoa ka ho fetisisa ea Lithium Bromide ke tsamaisong ea mocheso, moo e nolofalletsang ho pholisa ka katleho le ka mokhoa o tsitsitseng.
* Ho Monya Sehatsetsi: Tharollo ea metsi ea 50-60% ea LiBr ke mokelikeli o tloaelehileng o sebetsang ka har'a li-chiller tse kholo tse monyang. Mekhoa ena e sebelisa mocheso (o tsoang mouoane o litšila, mocheso oa letsatsi, kapa khase ea tlhaho) ho e-na le matla a mangata a motlakase ho khanna ts'ebetso ea ho pholisa, e fanang ka tharollo e bolokang matla bakeng sa:
* Mekhoa ea ho Pholisa ea Setereke
* Ho Pholisa Ts'ebetso ea Liindasteri
* Mekhoa e Meholo ea HVAC ea Khoebo
2. Ho Kopanya le ho Sebetsa ha Lik'hemik'hale
Liindastering tsa lik'hemik'hale le meriana, LiBr e tiileng e nkoa e le sesebelisoa se matla le se feto-fetohang.
* Lewis Acid Catalyst: E nolofalletsa mefuta e fapaneng ea liphetoho tsa tlhaho, ho kenyeletsoa le oxidation, hydroformylation, le cyclization reactions, ka lebaka la bokhoni ba eona ba ho hokahana le lihlopha tse sebetsang tsa tlhaho.
* Mohlohlelletsi oa Karabelo: E sebelisoa mehatong ea ho tlosa protonation le ho felloa ke metsi 'meleng bakeng sa metsoako e bonolo ea asiti, e nolofalletsang ho kopanngoa ha meaho e rarahaneng ea limolek'hule.
* Moemeli oa Tlhoekiso: O thusa ho hloekiseng limolek'hule tse rarahaneng tsa lintho tse phelang, tse kang li-steroid le li-prostaglandin, nakong ea tlhahiso.
3. Saense ea Meriana le Bophelo
Leha tšebeliso ea eona ea kalafo e fokotsehile, LiBr e ntse e le moemeli oa bohlokoa oa ts'ebetso tlhahisong ea meriana.
* Khemikhale e Mahareng: E nka karolo ho kopanyeng metsoako e sebetsang ea meriana (API).
* Sesebediswa sa ho Omisa: Ho ba ha yona ka tsela e feteletseng ho sebediswa ho laola mongobo ditshebetsong tse ikgethang tsa tlhahiso.
* Tšebeliso ea Nalane: Pele e ne e sebelisoa e le sethethefatsi se kokobetsang le bakeng sa maemo a kang lefu la ho ferekana kelellong, ts'ebeliso ea eona ea bongaka e nketsoe sebaka ke meriana e sireletsehileng le ea sejoale-joale.
4. Likopo tse Ikhethileng tsa Liindasteri
* Theknoloji ea ho Nka Lifoto: Ho qhibiliha ha eona haholo lithakong tsa tlhaho tse kang joala le ether ho entse hore e be karolo ea bohlokoa tlhahisong ea li-emulsion tsa poleiti e omileng ea collodion ho lifoto tsa setso.
* Taolo ea Mongobo: E sebelisoa lits'ebetsong tse ikhethileng tsa ho omisa moea tsa indasteri moo ho hlokahalang ho monya mongobo ka nepo.
* Patlisiso le Saense ea Lintho: E sebelisoa kholong ea kristale le lits'ebetsong tse ling tsa laboratori tse sebelisang thepa ea eona e tsitsitseng ea ionic.

Litšobotsi tsa Bohlokoa le Melemo:
* Hygroscopicity e Ikhethang: E sebetsa hantle haholo ho monyeng mouoane oa metsi, e leng se etsang hore e be ntle bakeng sa ho monya le ho omisa.
* Ho qhibiliha ho Hoholo: E bonts'a ho qhibiliha ho babatsehang metsing le li-solvents tsa tlhaho tsa polar, e leng se fanang ka ho tenyetseha ha sebopeho.
* Ho Tsitsisa Thermodynamic: E fana ka tshebetso e tshepahalang maemong a indasteri a hlokang boiteko bo boholo, jwalo ka hara di-chiller tsa ho monya mocheso o phahameng.
* Sesebediswa se Feto-fetohang: Se sebetsa e le sesebelisoa sa ho baka, ho khothaletsa le ho hloekisa metsoako e rarahaneng ea lik'hemik'hale.
Tlhokomeliso: Lithium Bromide e lokela ho sebetsoa ka hloko e loketseng, kaha litharollo tse kopaneng li ka senya. Ke boikarabello ba mosebelisi ho netefatsa mekhoa e sireletsehileng ea ho sebetsana le sehlahisoa le ho fumana hore na se loketse ts'ebeliso ea sona e ikhethileng ho latela melaoana eohle e amehang.
