I-Lithium hydride CAS 7580-67-8 99% ubunyulu njenge-arhente yokunciphisa
Ingcaciso yeMveliso
I-Lithium hydride yinto emhlophe-emhlophe ukuya kwengwevu, eguquguqukayo, engenavumba eliqinileyo okanye umgubo omhlophe othi ube mnyama ngokukhawuleza ekutyhilekeni ekukhanyeni. Ubunzima bemolekyuli = 7.95; Specificgravity (H2O:1)=0.78; Indawo yokubilisa = 850℃ (ibola ngaphantsi kweBP); Indawo yokukhenkceza/yokunyibilika = 689℃; Autoignitiontemperature = 200℃. Ukuchongwa kweHazard (okusekwe kwiNFPA-704 M Inkqubo yokuHlola): IMpilo 3, Ukutsha 4, Ukusebenza kwakhona 2. Isiqina esinokutsha esinokwenza amafu e-airbornedust anokudubula xa edibene nedangatye, ubushushu, okanye i-oxidizers.
Iipropati zeMveliso
I-Lithium hydride (i-LiH) yinto yetyuwa eyikristale (i-cubic yobuso-centered) emhlophe ngendlela ecocekileyo, Njengesixhobo sobunjineli, ineempawu ezinomdla kwiiteknoloji ezininzi. Umzekelo, umxholo ophezulu we-hydrogen kunye nobunzima obulula be-LiH buyenza ibe luncedo kwizikhuselo ze-neutron kunye neemodareyitha kwizityalo zamandla enyukliya. Ukongezelela, ukushisa okuphezulu kokudibanisa okudityanisiweyo kunye nobunzima obulula kwenza i-LiH ifaneleke kwimidiya yokugcina ukushisa kwizityalo zamandla elanga kwiisathelayithi kwaye inokusetyenziswa njengento yokutshisa ukushisa kwizicelo ezahlukeneyo. Ngokuqhelekileyo, iinkqubo zokuvelisa i-LiH zibandakanya ukuphathwa kwe-LiH kumaqondo obushushu ngaphezu kwendawo yokunyibilika kwayo (688 DC). Uhlobo lwe-304L yensimbi engenasici isetyenziselwa izinto ezininzi zenkqubo yokuphatha i-LiH etyhidiweyo.
I-Lithium hydride yi-ionic hydride eqhelekileyo ene-lithium cations kunye ne-hydride anions. I-Electrolysis yezinto ezityhidiweyo iphumela ekubunjweni kwesinyithi se-lithium kwi-cathode kunye ne-hydrogen kwi-anode. I-lithium hydride-water reaction, ephumela ekukhutshweni kwegesi ye-hydrogen, iphinda ibonise i-hydrogen ehlawuliswa kakubi.
I-Lithium hydride yinto emhlophe-emhlophe ukuya kwengwevu, eguquguqukayo, engenavumba eliqinileyo okanye umgubo omhlophe othi ube mnyama ngokukhawuleza ekutyhilekeni ekukhanyeni. I-lithium hydride ecocekileyo yenza iikristale ezingenambala, ze-cubic. Imveliso yorhwebo iqulethe imiqondiso yokungcola, umzekelo, isinyithi se-lithium esingaphendulwanga, kwaye ngenxa yoko i-gray ekhanyayo okanye eluhlaza okwesibhakabhaka. I-Lithium hydride izinze kakhulu ngokwe-thermal, ibe kuphela kwe-ionic hydride enyibilikayo ngaphandle kokubola kuxinzelelo lwe-atmospheric (mp 688 ℃). Ngokuchaseneyo nezinye iihydrides zesinyithi zealkali, i-lithium hydride inyibilika kancinane kwizinyibilikisi ze-polar organic ezinert ezifana ne-ethers. Yenza imixube ye-eutectic enenani elikhulu leetyuwa. I-lithium hydride izinzile kumoya owomileyo kodwa ivutha kubushushu obongeziweyo. Kumoya omanzi i-hydrolyzed exothermically; izinto ezahlulwe kakuhle zinokuvutha ngokuzenzekelayo. Kwiqondo lokushisa eliphakamileyo, liphendula nge-oksijini ukwenza i-lithium oxide, kunye ne-nitrogen ukwenza i-lithium nitride kunye ne-hydrogen, kunye ne-carbon dioxide ukwenza i-lithium formate.
Isicelo
I-lithium hydride isetyenziswa ekwenzeni i-lithium aluminiyam hydride kunye ne-silane, njenge-ejenti yokunciphisa enamandla, njenge-condensationagent kwi-organic synthesis, njengomthombo ophathwayo we-hydrogen, nanjengesixhobo sokukhusela inyukliya esikhaphukhaphu. Ngoku isetyenziselwa ukugcina amandla ashushu kwiinkqubo zamandla asemajukujukwini.
I-Lithium hydride yikristale e bluish-mhlophe enokutsha ekufuma. Isetyenziswa njengomthombo werhasi yehydrogen ethi ikhululwe xa i-LiH iba manzi. I-LiH yeyona nto igqwesileyo ye-desiccant kunye ne-arhente yokunciphisa kunye nekhaka elikhusela kwimitha yemitha edalwe ziintshukumo zenyukliya.
Ukupakisha kunye noGcino
Ukupakisha: 100g / inkonkxa; 500g/inkonkxa; 1kg ngetoti nganye; 20kg igubu lentsimbi ngalinye
Ukugcinwa: Inokugcinwa kwiitoti zetsimbi kunye nekhava yangaphandle yokukhusela, okanye kwiidramu zetsimbi ukukhusela umonakalo owenziwe ngoomatshini. Gcina kwindawo eyahlukileyo, epholileyo, eyomileyo kwaye engenamoya, kwaye uthintele ngokungqongqo ukufuma. Izakhiwo kufuneka ziphefumle kakuhle kwaye zingabinarhasi.
