I-R43 – Inokubangela uvakalelo ngokudibana nolusu I-R19 – Isenokwenza iiperoxide ezidubulayo R68 – Umngcipheko onokubakho weziphumo ezingajikiyo R50/53 – Ityhefu kakhulu kwizinto eziphila emanzini, inokubangela iziphumo ezibi zexesha elide kwindawo ehlala emanzini. |
Inkcazelo yoKhuseleko | S53 – Kuphephe ukuba sesichengeni – fumana imiyalelo eyodwa phambi kokusetyenziswa. S43 – Kwimeko yokusetyenziswa komlilo … (lulandela uhlobo lwezixhobo zokucima umlilo eziza kusetyenziswa.) S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S43A - S36/37/39 – Nxiba iimpahla ezikhuselayo ezifanelekileyo, iiglavu kunye nokhuseleko lwamehlo/ubuso. S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S22 – Musa ukuphefumla uthuli. S50-Sukuxubana ne... S36/37 – Nxiba iimpahla ezifanelekileyo zokukhusela kunye neeglavu. S61 –Kuphephe ukukhutshelwa kokusingqongileyo. Jonga kwimiyalelo ekhethekileyo / kumaphepha edatha yokhuseleko. |

Intshayelelo
I-sodium borohydride yi-inorganic compound. Ingumgubo oqinileyo onyibilika ngokulula emanzini kwaye uvelise isisombululo sealkaline.
I-sodium borohydride ineepropati zokunciphisa ezomeleleyo kwaye inokusabela kwizinto ezininzi eziphilayo. Isetyenziswa ngokubanzi kwi-organic synthesis kwaye ihlala isetyenziswa njenge-agent ye-hydrogenating. I-sodium borohydride inokunciphisa i-aldehydes, i-ketones, i-esters, njl njl kwii-alcohols ezihambelanayo, kwaye inokunciphisa i-asidi kwii-alcohols. I-sodium borohydride ingasetyenziswa kwi-decarboxylation, dehalogenation, denitrification kunye nezinye iimpendulo.
Ukulungiswa kwe-sodium borohydride ngokuqhelekileyo kufunyanwa ngokusabela kwe-borane kunye nesinyithi se-sodium. Okokuqala, isinyithi se-sodium sisabela nge-hydrogen ukulungiselela i-sodium hydride, kwaye emva koko iphendule nge-trimethylamine borane (okanye i-triethylaminoborane) kwi-solvent ye-ether ukufumana i-borohydride ye-sodium.
I-sodium borohydride yi-arhente yokunciphisa eyomeleleyo esabela ngokukhawuleza ngokufuma kunye neoksijini emoyeni ukukhulula i-hydrogen. Isitya kufuneka sivalwe ngokukhawuleza kwaye sigcinwe somile ngexesha lokusebenza. I-sodium borohydride iphinda isebenze ngokulula kunye neeasidi ukukhulula igesi ye-hydrogen, kwaye ukudibana neeasidi kufuneka kuphetshwe. I-sodium borohydride nayo iyityhefu, kwaye kufuneka kuthathelwe ingqalelo ukuphepha ukuphefumla okanye ukudibana kwesikhumba. Xa usebenzisa i-sodium borohydride, nxiba iiglavu zokukhusela kunye neeglasi, kwaye uqinisekise ukuba umsebenzi wenziwa kwindawo enomoya ococekileyo.
