Ubungozi Nokuphepha
| Amakhodi Engozi | I-R22 – Iyingozi uma igwinywe R51/53 – Ukuba nobuthi ezintweni eziphila emanzini, kungabangela imiphumela emibi yesikhathi eside endaweni yasemanzini. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R21/22 – Kuyingozi ukuthinta isikhumba futhi uma ugwinyiwe. |
| Incazelo Yokuphepha | I-S61 - Gwema ukudedelwa endaweni. Bheka imiyalelo ekhethekile / amaphepha edatha okuphepha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-Ethyltriphenylphosphine bromide, eyaziwa nangokuthi i-Ph₃PCH₂CH₂CH₃, iyinhlanganisela ye-organophosphorus. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-ethyltriphenylphosphine bromide:
Ikhwalithi:
I-Ethyltriphenylphosphine bromide iyikristalu engenambala ukuya kokuphuzi noma uketshezi olunephunga elinamandla le-benzene. Iyancibilika kuzincibilikisi zemvelo ezifana nama-ether nama-hydrocarbons ezingeni lokushisa legumbi. Ine-solubility ephansi kunamanzi.
Sebenzisa:
I-Ethyltriphenylphosphine bromide inohlu olubanzi lwezinhlelo zokusebenza ku-organic synthesis. Isebenza njenge-reagent ye-phosphorus yokufaka esikhundleni se-nucleophilic yama-athomu e-halogen kanye nokusabela kwe-nucleophilic kwe-carbonyl compounds. Ingasetshenziswa futhi njenge-ligand ye-organometallic chemistry kanye ne-transition metal-catalyzed reactions.
Indlela:
I-Ethyltriphenylphosphine bromide ingalungiswa ngokusabela okulandelayo:
Ph₃P + BrCH₂CH₂CH₃ → Ph₃PCH₂CH₂CH₃ + HBr
Ulwazi Lokuphepha:
I-Ethyltriphenylphosphine bromide inobuthi obuphansi kodwa kusafanele isetshenziswe ngokuqapha. Ukuchayeka ku-ethyltriphenylphosphine bromide kungase kubangele ukucasuka nokulimala kwamehlo. Izinyathelo ezifanele zokuzivikela, njengokugqoka amagilavu nezibuko, kufanele zithathwe lapho kusetshenziswa, futhi kuqinisekiswe umoya omuhle. Gwema ukuhogela umhwamuko wayo noma ukuthintana nesikhumba namehlo ngesikhathi sokuhlinzwa.
