Intshayelelo
I-Acid (i-asidi) yi-organic compound. Ine-formula yekhemikhali ye-C6H4FNO2 kunye ne-molecular weight ye-141.1g / mol.
Ngokwendalo, iasidi yinto eqinileyo emhlophe ukuya kumthubi. Ine-oxidation eyomeleleyo kunye ne-corrosion, inokunyibilika kwezinye izinyibilikisi eziphilayo ezifana notywala kunye ne-ether, kodwa ukunyibilika kwamanzi kumbi.
Olunye lolona setyenziso luphambili lwe-asidi luyinto ephakathi kwi-organic synthesis. Isetyenziswa ngokuqhelekileyo ekulungiseleleni amayeza, i-pesticides kunye nezinye izinto eziphilayo. Ukongeza, inokusetyenziswa njenge-ligand ye-organometallic complex.
Indlela yokulungiselela i-calcium idla ngokufunyanwa ngale ndlela ilandelayo: Okokuqala, i-2-fluoropyridine iphendulwa nge-acetone kunye ne-aluminium trichloride kwi-dichloromethane ukuvelisa i-2-fluoropyridine-4-methanone. Emva koko, i-2-fluoropyridine-4-methanone yaguqulwa yaba yi-fluoracid nge-acid-catalyzed reaction.
Ngokumalunga nolwazi lokhuseleko, iasidi yikhemikhali ephilayo enokubangela ingozi kwimpilo yabantu nakwimekobume. Landela iindlela ezifanelekileyo zokhuseleko ngexesha lokuphatha kunye nokugcinwa ukuze ugweme ukudibanisa nolusu, amehlo kunye nomgudu wokuphefumla. Izixhobo zokuzikhusela ezifana neeglavu zelebhu, iiglasi kunye neemaski zokhuselo kufuneka zinxitywe xa zisetyenziswa. Ukongeza, kufuneka igcinwe kwindawo epholileyo, eyomileyo, kude nomlilo kunye ne-oxidizing agents. Ukuba kuyimfuneko, sebenza kwindawo engenamoya. Ngokumalunga nokulahlwa kwenkunkuma, imithetho nemigaqo yendawo kufuneka ilandelwe.
