Intshayelelo
I-Ethyltriphenylphosphine bromide, ekwabizwa ngokuba yi-Ph₃PCH₂CH₂CH₃, yi-organophosphorus compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-ethyltriphenylphosphine bromide:
Umgangatho:
I-Ethyltriphenylphosphine bromide yikristale engenambala ukuya kwetyheli okanye ulwelo kunye nevumba elimnandi lebenzene. Iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-ethers kunye ne-hydrocarbons kwiqondo lobushushu begumbi. Inonyibiliko olusezantsi kunamanzi.
Sebenzisa:
I-Ethyltriphenylphosphine bromide inoluhlu olubanzi lwezicelo kwi-organic synthesis. Isebenza njenge-reagent ye-phosphorus yokutshintshwa kwe-nucleophilic ye-athomu ye-halogen kunye neempendulo ze-nucleophilic ezongezelelweyo ze-carbonyl compounds. Inokusetyenziswa kwakhona njenge-ligand ye-organometallic chemistry kunye ne-transition metal-catalyzed reactions.
Indlela:
I-Ethyltriphenylphosphine bromide inokulungiswa ngolu hlobo lulandelayo:
Ph₃P + BRCH₂CH₂CH₃ → Ph₃PCH₂CH₂CH₃ + HBr
Ulwazi ngoKhuseleko:
I-Ethyltriphenylphosphine bromide inetyhefu esezantsi kodwa kusafuneka isetyenziswe ngononophelo. Ukuvezwa kwi-ethyltriphenylphosphine bromide kunokubangela ukucaphuka kunye nomonakalo wamehlo. Amanyathelo afanelekileyo okuzikhusela, anjengokunxiba iiglavu neeglavu, kufanele kuthatyathwe xa usetyenziswa, yaye kuqinisekwe kungena umoya olungileyo. Kuphephe ukuphefumla umphunga wayo okanye ukudibana nolusu namehlo ngexesha lotyando.
