Intshayelelo
I-3,5-Dichloropyridine i-organic compound. Lulwelo olungenambala kunye nevumba elibukhali elibukhali.
I-3,5-dichloropyridine ikwakhawuleza ukusabela kunye nesodium hydroxide ukwenza igesi eyityhefu yehydrogen chloride.
I-3,5-Dichloropyridine inoluhlu olubanzi lwezicelo kwinkqubo ye-organic synthesis. Ingasetyenziselwa njenge-arhente ebalulekileyo yokunciphisa ukuhlanganiswa kwee-ketones.
Kukho iindlela ezininzi zokulungisa i-3,5-dichloropyridine. Indlela eqhelekileyo ifunyenwe ngokuphendula i-pyridine ngegesi ye-chlorine. Amanyathelo athile abandakanya: ukuqaliswa kwegesi ye-chlorine kwisisombululo esine-pyridine phantsi kweemeko ezifanelekileyo zokuphendula. Emva kokuphendula, imveliso ye-3,5-dichloropyridine yahlanjululwa yi-distillation.
Xa usebenzisa i-3,5-dichloropyridine, iinkqubo ezihambelanayo zokhuseleko kufuneka zilandelwe kwaye izixhobo zokukhusela kufuneka zigqitywe. Kuphephe ukudibana nolusu, amehlo kunye nenwebu. Kufuneka kuthatyathwe unonophelo ukuyithintela ukuba ingadibani nezinye iikhemikhali ngexesha lokuphathwa nokugcinwa ukuze kuthintelwe iingozi. Ngexesha lokugcinwa, i-3,5-dichloropyridine kufuneka igcinwe kwisitya esingenawo umoya kwaye sibekwe kwindawo epholileyo neyomileyo.
