Intshayelelo
I-Acid i-organic compound kunye ne-chemical formula C7H7NO2. Yikristale engenambala eqinileyo, enyibilikayo emanzini nakwizinyibilikisi zendalo.
I-Acid ineendlela ezahlukeneyo zokusetyenziswa. Ingasetyenziselwa njengendawo ephakathi kwi-organic synthesis yokulungiselela ezinye iikhompawundi. Inokuthi isebenze njenge-ligand ye-organometallic complexes kwaye ithathe inxaxheba kwi-catalytic reactions. Ukongeza, inokusetyenziswa kwakhona kwi-synthesis yamachiza athile.
Zininzi iindlela zokulungisa i-ICT. Enye indlela eqhelekileyo yi-synthesis ngonyango kunye ne-oxidation ye-toluene. Ngokukodwa, i-toluene iqala ukusabela nge-acetaldehyde phambi kwe-agent e-oxidizing ukuvelisa i-3-methyl-4-picolinic acid ester, enokuthi ifakwe kwi-acid hydrolysis ukuze ifumane imveliso ejoliswe kuyo.
Ukhuseleko lweasidi luphezulu, kodwa eminye imiba yokhuseleko isafuna ukuhoywa. Nxiba izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu kunye neeglavu ngexesha lokusebenza. Gwema ukuphefumla uthuli olubangelwayo kunye negesi kwaye ugweme ukudibanisa nolusu. Ngexesha lokugcinwa kunye nokuthutha, ingqwalasela kufuneka ihlawulwe kubungqina bobumanzi, ubungqina bomlilo kunye nemilinganiselo yokuqhuma. Kwimeko yokungenwa ngengozi okanye ukudibana, funa iingcebiso zonyango ngokukhawuleza kwaye uzise iphepha ledatha yokhuseleko yale mveliso esibhedlele.
