I-Lithium hydride CAS 7580-67-8 99% ubumsulwa njenge-ejenti yokunciphisa
Incazelo Yomkhiqizo
I-Lithium hydride iyimpushana emhlophe-emhlophe ukuya kokumpunga, eshintshashintshayo, engenaphunga noma emhlophe eba mnyama ngokushesha lapho ichayeka ekukhanyeni. Isisindo samangqamuzana = 7.95; I-Specificgravity (H2O:1)=0.78; Indawo yokubilisa = 850℃ (ibola ngaphansi kwe-BP); Indawo yokubanda/incibilika = 689℃; I-Autoignitiontemperature = 200 ℃. Ukuhlonzwa kweHazard (okusekelwe ku-NFPA-704 M Uhlelo Lokulinganisa): Impilo 3, Ukuvutha 4, Ukuphinda Usebenze 2. Into eqinile evuthayo engakha amafu e-airboreddust angase aqhume lapho ethintana nelangabi, ukushisa, noma okoxidizer.
Izakhiwo Zomkhiqizo
I-Lithium hydride (LiH) iwuketshezi oluwusawoti oluyikristalu(i-cubic egxile ebusweni) emhlophe ngendlela emsulwa, Njengento yobunjiniyela, inezinto ezithakaselwayo kubuchwepheshe obuningi. Isibonelo, okuqukethwe okuphezulu kwe-hydrogen nesisindo esilula se-LiH sikwenza kube usizo kumahawu namamoderetha e-neutron ezikhungweni zamandla enuzi. Ukwengeza, ukushisa okuphezulu kwe-fusion kuhlanganiswe nesisindo esilula kwenza i-LiH ifanele imidiya yokugcina ukushisa yezitshalo zamandla elanga kumasathelayithi futhi ingasetshenziswa njengendawo yokushisa yezinhlelo zokusebenza ezahlukene. Imvamisa, izinqubo zokukhiqizwa kwe-LiH zibandakanya ukuphatha i-LiH emazingeni okushisa angaphezu kwendawo yayo yokuncibilika (688 DC). Uhlobo lwensimbi engagqwali engu-304L lusetshenziselwa izingxenye eziningi zenqubo ezibamba i-LiH encibilikisiwe.
I-Lithium hydride iyi-ionic hydride ejwayelekile ene-lithium cations nama-hydride anions. I-Electrolysis yezinto ezincibilikisiwe iphumela ekwakhekeni kwensimbi ye-lithium ku-cathode ne-hydrogen ku-anode. Ukusabela kwe-lithium hydride-water, okuholela ekukhishweni kwegesi ye-hydrogen, nakho kuyinkomba ye-hydrogen ekhokhiswa kabi.
I-Lithium hydride iyimpushana emhlophe-emhlophe ukuya kokumpunga, eshintshashintshayo, engenaphunga noma emhlophe eba mnyama ngokushesha lapho ichayeka ekukhanyeni. I-lithium hydride ehlanzekile yakha amakristalu angenambala, ama-cubic. Umkhiqizo wentengiso uqukethe imikhondo yokungcola, isb, insimbi ye-lithium engaphenduliwe, futhi ngenxa yalokho iba mpunga okhanyayo noma oluhlaza okwesibhakabhaka. I-Lithium hydride izinzile kakhulu ngokushisa, okuwukuphela kwe-ionic hydride encibilika ngaphandle kokubola kungcindezi yomoya (mp 688 ℃). Ngokuhlukile kwamanye ama-alkali metal hydride, i-lithium hydride incibilika kancane kuzincibilikisi zemvelo ze-polar ezingasebenzi njenge-ethers. Yakha izingxube ze-eutectic nenani elikhulu likasawoti. I-lithium hydride izinzile emoyeni owomile kodwa ivutha ngokukhuphuka kwezinga lokushisa. Emoyeni omanzi i-hydrolyzed exothermically; impahla ehlukaniswe kahle ingavutha ngokuzenzekelayo. Emazingeni okushisa aphakeme, ihlangana nomoya-mpilo ukwenza i-lithium oxide, ne-nitrogen yakhe i-lithium nitride ne-hydrogen, kanye ne-carbon dioxide yakhe i-lithium formate.
Isicelo
I-Lithium hydride isetshenziswa ekwenziweni kwe-lithium aluminium hydride kanye ne-silane, njenge-ejenti yokunciphisa enamandla, njenge-condensation ku-organic synthesis, njengomthombo ophathwayo we-hydrogen, nanjengento engasindi yokuvikela yenuzi. Manje isisetshenziselwa ukugcina amandla ashisayo kumasistimu wamandla omkhathi .
I-Lithium hydride iyikristalu eluhlaza okwesibhakabhaka nokumhlophe evutha kalula emswakameni. Isetshenziswa njengomthombo wegesi ye-hydrogen ekhululwa lapho i-LiH iba manzi. I-LiH iyi-desiccant enhle kakhulu ne-ejenti yokunciphisa kanye nesihlangu esivikela emisebeni edalwe ukusabela kwenyukliya.
Ukupakisha & Isitoreji
Ukupakisha: 100g/ tin can; 500g / ithini ithini; 1kg ithini ngalinye; 20kg isigubhu sensimbi ngasinye
Isitoreji: Ingagcinwa emathinini ensimbi anekhava yangaphandle ukuze ivikeleke, noma ezigubhu zensimbi ukuvikela ukulimala komshini. Gcina endaweni ehlukile, epholile, eyomile futhi enomoya omuhle, futhi uvimbele umswakama ngokuqinile. Izakhiwo kumele zibe nomoya omuhle futhi zingabi negesi enqwabelene.
