Ubungozi Nokuphepha
| Amakhodi Engozi | R15 – Ukuthintana namanzi kukhulula amagesi avuthayo kakhulu R25 – Kunobuthi uma ugwinywe R36/38 – Ukucasuka emehlweni nasesikhumbeni. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| 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.) S36 – Gqoka izingubo ezifanele zokuzivikela. |

I-Tetramethylammonium borohydride (CAS# 16883-45-7) isingeniso
I-Tetramethylammonium borohydride iyinhlanganisela evamile ye-organoboron. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-Tetramethylammonium borohydride iyikristale eqinile engenambala encibilika kalula emanzini. Kuyi-alkaline ebuthakathaka ehlangana nama-asidi yakhe usawoti ohambisanayo. Izwela ukukhanya nokushisa futhi kufanele igcinwe endaweni epholile, eyomile.
Sebenzisa:
I-Tetramethylammonium borohydride ivame ukusetshenziswa njenge-catalyst ekuphenduleni kwamakhemikhali ku-organic synthesis. Ingasetshenziswa ekuhlanganiseni kwe-organoboron compounds, boranes, nezinye izinhlanganisela. Ngaphezu kwalokho, ingasetshenziswa futhi njenge-ejenti yokunciphisa ukunciphisa ama-ion ensimbi noma ama-organic compounds, futhi ingasetshenziswa ukuhlanganisa izinhlanganisela zensimbi-organic.
Indlela:
Ukulungiswa kwe-tetramethylboroammonium hydride kuvame ukusebenzisa ukusabela kwe-methyllithium ne-trimethylborane. I-Lithium methyl ne-trimethylborane isabela emazingeni okushisa aphansi ukuze yenze i-lithium methylborohydride. Khona-ke, i-lithium methylborohydride isabela nge-methylammonium chloride ukuze ithole i-tetramethylammonium borohydride.
Ulwazi Lokuphepha:
I-Tetramethylammonium borohydride iphephile uma kuqhathaniswa ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Kufanele kuqashelwe ukugwema ukuthintana nesikhumba, amehlo noma umlomo lapho uphethe noma uphathwa. Kufanele igcinwe kude nemithombo yomlilo kanye nezinto ezivuthayo futhi igcinwe esitsheni esingangenisi umoya.
