Lithium Bromide (LiBr)
Lithium Bromide (LiBr), ib qho tshuaj hygroscopic uas muaj lithium thiab bromine, yog siv dav hauv kev lag luam thiab kev siv tshuaj vim nws cov khoom tshwj xeeb physicochemical. Nws yog synthesized los ntawm kev tshuaj xws li kho lithium carbonate nrog hydrobromic acid lossis reacting lithium hydroxide nrog bromine, ua rau crystalline hydrates sib txawv ntawm lwm cov alkali hlau bromides.
LiBr muaj peev xwm yaj tau zoo heev hauv dej, cawv, thiab ether, nrog rau cov kua dej uas muaj zog uas muaj cov pa dej tsawg. Cov yam ntxwv no, ua ke nrog nws cov hygroscopicity siab, ua rau nws yog ib qho desiccant thiab kua sorbent zoo, tshwj xeeb tshaj yog nyob rau hauv kev nqus tub yees thiab cua txias. Tsis tas li ntawd, nws lub peev xwm los yaj cov organic compounds polar xws li cellulose nthuav nws cov txiaj ntsig hauv cov txheej txheem tshuaj tshwj xeeb, suav nrog catalytic dehydrohalogenation rau olefin synthesis.
Hauv kev kho dej thiab kev siv cov khoom siv lead ua kom loj hlob, LiBr qhov solubility thiab cov qauv purity siab heev (submicron / nanopowders) yog qhov zoo. Cov bromide ion tuaj yeem pom hauv cov kua dej siv cov carbon disulfide thiab chlorine. Txawm li cas los xij, kev tuav yuav tsum ceev faj: LiBr tsim cov cua sov loj thaum yaj (vim yog qhov tsis zoo ntawm cov kua) thiab ua rau muaj kev phom sij ua cov tshuaj corrosive thiab psychoactive me ntsis.
UrbanMines muab LiBr hauv ntau qib (Mil Spec, ACS, Pharmaceutical, thiab lwm yam), cov kev xaiv ntim khoom, thiab cov purities, ua raws li ASTM, USP, thiab EP/BP cov qauv. Kev txhawb nqa kev txawj ntse, cov ntaub ntawv kev nyab xeeb (MSDS), thiab cov cuab yeej hloov pauv unit tau muab los xyuas kom muaj kev nyab xeeb thiab kev siv tau zoo tshaj plaws thoob plaws hauv kev lag luam.
