Okwu mmalite
Ethyltriphenylphosphine bromide, makwaara dị ka Ph₃PCH₂CH₂CH₃, bụ ogige organophosphorus. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke ethyltriphenylphosphine bromide:
Ogo:
Ethyltriphenylphosphine bromide bụ kristal edo edo na-acha odo odo ma ọ bụ mmiri mmiri nwere isi benzene siri ike. Ọ bụ soluble na organic mgbaze dị ka ethers na hydrocarbons na ụlọ okpomọkụ. Ọ nwere obere solubility karịa mmiri.
Jiri:
Ethyltriphenylphosphine bromide nwere ọtụtụ ngwa na njikọ organic. Ọ na-arụ ọrụ dị ka ihe reagent nke phosphorus maka nnọchi nucleophilic nke halogen atọm na mmeghachi omume mgbakwunye nucleophilic nke ogige carbonyl. Enwere ike iji ya dị ka ligand maka kemịkalụ organometallic na ngbanwe metal-catalyzed mmeghachi omume.
Usoro:
Enwere ike ịkwadebe ethyltriphenylphosphine bromide site na mmeghachi omume ndị a:
Ph₃P + BrCH₂CH₂CH₃ → Ph₃PCH₂CH₂CH₃ + HBr
Ozi nchekwa:
Ethyltriphenylphosphine bromide nwere obere toxicity mana a ka kwesịrị iji nlezianya mee ya. Ngosipụta na ethyltriphenylphosphine bromide nwere ike ịkpasu iwe na mmebi anya. Ekwesịrị ịkpachapụ anya kwesịrị ekwesị, dị ka iyi uwe aka na enyo enyo, mgbe a na-eji ya, na ekwesịrị ijide n'aka na ikuku ikuku dị mma. Zere ikuku ume ya ma ọ bụ bata na akpụkpọ ahụ na anya mgbe ị na-arụ ọrụ.
