Intshayelelo
I-Methyl fluorobenzoate yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methylparaben:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala.
- Ukunyibilika: Inyibilika kwizinyibilikisi zendalo ezifana ne-ethers, iialkoholi kunye nee-esters, ezinganyibilikiyo emanzini.
Sebenzisa:
- I-Methyl fluorobenzoate ingasetyenziselwa njengento ebalulekileyo ephakathi kwi-organic synthesis.
Indlela:
- Kukho iindlela ezininzi zokwenziwa kwe-methyl fluorobenzoate, kwaye indlela esetyenziswa ngokuqhelekileyo ifunyenwe ngokusabela kwe-fluororeagent kunye ne-methyl benzoate. Ngokuqhelekileyo, i-methyl fluorobenzoate inokufumaneka ngokubeka i-fluorobenzene kunye ne-methyl benzoate phantsi kwesenzo se-agent ye-polycondensation efana ne-Lewis acid (umzekelo, i-aluminium chloride).
Ulwazi ngoKhuseleko:
- IMethyl fluorobenzoate yinto ephilayo, kwaye kufuneka kuthathwe amanyathelo okhuseleko alandelayo xa uyisebenzisa:
- Kuphephe ukudibana ngqo nolusu namehlo.
- Kuphephe ukuphefumla umphunga kwaye usebenze ngokungena komoya okwaneleyo okanye unxibe ukhuseleko olufanelekileyo lokuphefumla.
- Gcina kude nomlilo, amaqondo obushushu aphezulu kunye nokukhanya kwelanga.
- Ngexesha lokusetyenziswa kunye nokugcinwa, nceda ubhekisele kwizikhokelo ezifanelekileyo zokuphatha ukhuseleko kunye namaphepha edatha yokhuseleko lwezinto eziphathekayo.
