I-Lithium Bromide (LiBr)
I-Lithium Bromide (LiBr), ikhompawundi exutywe ne-hygroscopic eyenziwe yi-lithium kunye ne-bromine, isetyenziswa kakhulu kwimveliso nakwiikhemikhali ngenxa yeempawu zayo ezikhethekileyo ze-physicochemical. Yenziwa ngeempendulo ezifana nokunyanga i-lithium carbonate nge-hydrobromic acid okanye i-lithium hydroxide esebenza nge-bromine, nto leyo evelisa ii-crystalline hydrate ezahlukileyo kwezinye ii-alkali metal bromides.
I-LiBr ibonakalisa ukunyibilika okumangalisayo emanzini, kwi-alcohol nakwi-ether, kunye nezisombululo zamanzi ezixineneyo ezibonisa uxinzelelo oluphantsi lomphunga wamanzi. Le mpawu, kunye ne-hygroscopicity yayo ephezulu, iyenza ibe yi-desiccant esebenzayo kunye ne-sorbent yolwelo, ngakumbi kwiinkqubo zokufunxa kunye ne-air-conditioning. Ukongeza, amandla ayo okunyibilikisa iikhompawundi ze-polar organic ezifana ne-cellulose andisa ukusetyenziswa kwayo kwiinkqubo zeekhemikhali ezikhethekileyo, kubandakanya i-catalytic dehydrohalogenation yokwenza i-olefin.
Kwindlela yokucoca amanzi kunye nokukhulisa ikristale, ukunyibilika kweLiBr kunye neefom ze-ultra-high purity (submicron/nanopowders) ziluncedo. I-bromide ion inokubonwa kwizisombululo zamanzi kusetyenziswa i-carbon disulfide kunye ne-chlorine. Nangona kunjalo, ukuphathwa kufuna unonophelo: I-LiBr ivelisa ubushushu obukhulu xa inyibilika (ngenxa ye-enthalpy engalunganga yesisombululo) kwaye ibeka iingozi njengento erhabaxa kancinci kwaye echaphazela ingqondo.
I-UrbanMines ibonelela ngeLiBr kwiindidi ezahlukeneyo (iMil Spec, i-ACS, iPharmaceutical, njl.njl.), iindlela zokupakisha, kunye nokucoca, ithobela imigangatho ye-ASTM, i-USP, kunye ne-EP/BP. Inkxaso yobugcisa, idatha yokhuseleko (i-MSDS), kunye nezixhobo zokuguqula iiyunithi zibonelelwa ukuqinisekisa ukusetyenziswa okukhuselekileyo nokuphuculweyo kumashishini onke.
