| Amakhodi Engozi | R14/15 - R23/24/25 – Kunobuthi ngokuhogela, ukuthintana nesikhumba futhi uma ugwinywe. R34 – Ibangela ukusha R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. I-R11 – Ivutha Kakhulu R40 – Ubufakazi obuncane bomphumela we-carcinogenic R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R19 – Ingase yenze ama-peroxides aqhumayo R67 – Izihwamuko zingadala ukozela kanye nesiyezi R66 – Ukuchayeka kaningi kungabangela ukomisa kwesikhumba noma ukuqhekeka I-R22 – Iyingozi uma igwinywe I-R12 – Ivutha Kakhulu |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S43 – Uma kusetshenziswa umlilo … (kulandela uhlobo lwempahla yokucisha umlilo ezosetshenziswa.) S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. S16 – Zigcine kude nemithombo yokuthungela. |

Isingeniso
I-Lithium borohydride iyinhlanganisela ye-inorganic ne-chemical formula BH4Li. Kuyinto eqinile, ngokuvamile ngesimo se-white crystalline powder. I-Lithium borohydride inezici ezilandelayo:
1. Umthamo omkhulu wokugcina i-hydrogen: I-Lithium borohydride iyinto enhle kakhulu yokugcina i-hydrogen, engagcina i-hydrogen ngesilinganiso esikhulu sesisindo.
2. Ukunyibilika: I-Lithium borohydride inokunyibilika okuphezulu futhi ingancibilika kuzincibilikisi eziningi eziphilayo, njenge-ether, i-ethanol ne-THF.
3. Ukuvutha okuphezulu: I-Lithium borohydride ingashiswa emoyeni futhi ikhulule inani elikhulu lamandla.
Ukusetshenziswa okuyinhloko kwe-lithium borohydride yilezi:
1. Isitoreji se-hydrogen: Ngenxa yomthamo wayo omkhulu wokugcina i-hydrogen, i-lithium borohydride isetshenziswa kabanzi emkhakheni wamandla e-hydrogen ukugcina nokukhulula i-hydrogen.
2. Ukwenziwa kwe-Organic: I-Lithium borohydride ingasetshenziswa njenge-ejenti enciphisa ukusabela kwe-hydrogenation ekuphenduleni kwe-organic chemical synthesis.
3. Ubuchwepheshe bebhethri: I-Lithium borohydride ingasetshenziswa futhi njengesengezo se-electrolyte kumabhethri e-lithium-ion.
Indlela yokulungiselela i-lithium borohydride ngokuvamile ilungiswa ngokusabela kwe-lithium metal ne-boron trichloride. Indlela eqondile yokulungiselela imi kanje:
1. Ukusebenzisa i-ether anhydrous njenge-solvent, insimbi ye-lithium yengezwa ku-ether endaweni engasebenzi.
2. Engeza isisombululo se-ether se-boron trichloride ensimbi ye-lithium.
3. Ukusabela okushisa okushukumisayo nokuqhubekayo kuyenziwa, futhi i-lithium borohydride ihlungwa ngemva kokuba ukusabela kuqediwe.
1. I-Lithium borohydride kulula ukuyishisa lapho ithintana nomoya, ngakho gwema ukuthintana namalangabi avulekile kanye nezinto ezishisa kakhulu.
2. I-Lithium borohydride iyacasula esikhumbeni nasemahlweni, futhi izinto zokuzivikela ezifanele ezifana namagilavu nezibuko kufanele zigqokwe lapho usebenza.
3. I-Lithium borohydride kufanele igcinwe endaweni eyomile, kude namanzi kanye nendawo eswakeme, ukuyivimbela ekumunceni umswakama futhi ibole.
Sicela uqinisekise ukuthi uziqondile futhi wazi kahle izindlela zokusebenza nolwazi lokuphepha ngaphambi kokusebenzisa i-lithium borohydride. Uma ungaphephile noma ungabaza, kufanele ufune isiqondiso sochwepheshe.
