Intshayelelo
Yikhompawundi ephilayo enefomula yemichiza eyi-C8H6BrN. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: Ayinabala ukuya kwikristale etyheli
-Indawo yokunyibilika: 64-68 degrees Celsius
-Indawo yokubila: 294-296 degrees Celsius
-Ubuninzi: 1.51 g / ml
-Ukunyibilika: Inyibilika kancinane emanzini, inyibilika kwizinyibilikisi eziqhelekileyo ezifana ne-ethanol, i-ether kunye nebenzene
Sebenzisa:
Ihlala isetyenziswa njengendawo ephakathi kwi-organic synthesis kwaye ingasetyenziselwa ukulungisa ezinye izinto eziphilayo. Ingasetyenziswa kwi-pharmaceutical synthesis, i-pesticide synthesis, kunye nakwimizi-mveliso yedayi kunye nepeyinti.
Indlela yokuLungiselela: Ulungiselelo lwe
idla ngokuqhutywa ngala manyathelo alandelayo:
1. Yenza i-p-methylbenzonitrile kunye ne-bromine phantsi kweemeko ezifanelekileyo zokuphendula ukuvelisa i-phenol.
Ulwazi ngoKhuseleko:
-yinto enokubakho kwikhompawundi yendalo kwaye kufuneka iphathwe ngobunono.
-Ngexesha lokusebenza, kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa ngokuthe ngqo kwesikhumba, amehlo kunye nokuphefumula.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela, ezinjengeeglavu zaselebhu kunye neglavu.
-Kufuneka iqhutywe kwindawo engena umoya kwaye iphephe ukuphefumla umphunga wayo okanye uthuli.
-Ukuba uphefumle okanye ufakwe ngempazamo, funa uncedo lwezonyango ngokukhawuleza kwaye ubonise isitya okanye ileyibhile yereferensi.
Nceda uqaphele ukuba nayiphi na imichiza kufuneka isetyenziswe phantsi kweemeko ezifanelekileyo zelabhoratri kwaye ilandele iinkqubo ezifanelekileyo zokusebenza ezikhuselekileyo.
