Intshayelelo

I-2-Bromo-4-fluorobenzaldehyde i-organic compound.

 

Umgangatho:

I-2-Bromo-4-fluorobenzaldehyde yikristale emhlophe eqinileyo enevumba elikhethekileyo le-benzaldehyde. Iphantse yanganyibiliki emanzini kwiqondo lobushushu begumbi, kodwa inokunyibilika kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers, kunye neeketones.

 

Sebenzisa:

I-2-Bromo-4-fluorobenzaldehyde inoluhlu olubanzi lwezicelo kwi-organic synthesis.

 

Indlela:

Indlela yokudibanisa ye-2-bromo-4-fluorobenzaldehyde ifumaneka ikakhulu ngokusabela kwe-fluoroborate kunye ne-bromobenzaldehyde. Amanyathelo athile kukusabela i-fluoroborate kunye ne-bromobenzaldehyde phantsi kweemeko ze-acidic ukufumana i-2-bromo-4-fluorobenzaldehyde, kwaye emva koko uqhube amanyathelo athile onyango ekugqibeleni ufumane imveliso ekujoliswe kuyo.

 

Ulwazi ngoKhuseleko: Yinto eyingozi enokuba yingozi kumzimba womntu kunye nokusingqongileyo. Xa idibana nolusu kunye namehlo, inokubangela ukucaphuka kunye nokutshisa. Xa usebenza, kufuneka kunxitywe izixhobo ezifanelekileyo zokhuseleko ezifana neendondo zokhuseleko, iiglavu kunye nempahla yokuzikhusela. Xa ugcina, kufuneka igcinwe itywinwe ngokuqinileyo kwaye kude nomlilo kunye nemithombo yobushushu.
