Intshayelelo
I-2-Chloro-4-fluorobenzaldehyde yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokwenza, kunye nolwazi lokhuseleko:
Iimpawu: Lulwelo olungenambala ukuya kumthubi oluluthuthu olunevumba elinukayo. Ayinyibiliki emanzini kwiqondo lobushushu begumbi, kodwa inyibilika kwizinyibilikisi zendalo ezifana neealkoholi okanye ii-ethers.
Sebenzisa:
I-2-Chloro-4-fluorobenzaldehyde isoloko isetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis. Ingasetyenziselwa ukudibanisa i-biologically active compounds, kuquka i-oxachlors, imidazodones, i-aminoketones, kunye ne-aminoketones, phakathi kwabanye. Isenokusetyenziswa njengemathiriyeli ekrwada kwizitshabalalisi nezitshabalalisi.
Indlela:
I-2-Chloro-4-fluorobenzaldehyde inokulungiswa ngokuphendula kwe-2-chloro-4-fluorobenzoic acid kunye ne-sulfuric acid, i-thionyl chloride okanye i-phosphorus chloride. Le mpendulo isoloko iqhutywa kwindawo engasebenziyo kwaye ifuna ubushushu obufanelekileyo kunye nexesha lokusabela.
Ulwazi ngoKhuseleko:
I-2-Chloro-4-fluorobenzaldehyde iyingozi, kwaye kuyimfuneko ukunikela ingqalelo kwiimpawu zokhuseleko xa usebenzisa kwaye uyigcina. Inokucaphukisa kwaye yenze umhlwa emehlweni, ulusu, kunye nenkqubo yokuphefumla, kwaye izixhobo ezifanelekileyo zokukhusela ezifana neeglavu, iiglavu, kunye nezinto zokuphefumla kufuneka zinxitywe xa usebenza. Kuphephe ukudibana nolusu kunye nokuphefumla umphunga walo. Ngethuba lokusetyenziswa, indawo yokusebenza enomoya kakuhle kufuneka igcinwe, kwaye igcinwe kude namadangatye avulekileyo kunye namaqondo okushisa aphezulu. Kwimeko yokudibana nayo ngengozi, kufuneka ihlanjululwe ngokukhawuleza ngamanzi amaninzi kwaye ifune unyango.
