2-Chloro-5-nitropyridine CAS 4548-45-2 Codsiga

Habka diyaarinta ee isticmaalka dichlorine monoxide si loogu diyaariyo 2-chloro-5-nitropyridine waa in la isku qaso 3-nitropyridine iyo 1-3 jeer qadarka alkali ee saamiga molarka, 1-2 jeer qadarka milixda chloride iyo dareeraha ayaa si siman loo walaaqayaa , oo la qaboojiyey ilaa -15 ° C ilaa -10 ° C heerkul hoose; ka dib marka la milo 2-3 jeer saamiga molarka ee dichloride monoxide ee dareeraha, waxaa lagu dhex ridaa isku dhafka falcelinta hoostiisa oo si buuxda loo walaaqayo, waxaana lagu hayaa -10 ° C. Ilaa 0 ° C, ku-darka hoos u dhaca ayaa la dhammeeyey 2 saacadood, heerkulka ayaa kor loo qaaday heerkulka qolka oo wuxuu sii waday inuu walaaqo 2 saacadood ilaa falcelinta walxaha cayriin ee 3-nitropyridine la dhammeeyo, fal-celinta ayaa lagu shubay biyo baraf ah, lakabka organic waa la kala soocay, lakabka organic waa la ururiyey, iyo xooga saarida tirada badan ee lakabka organic waa ku maydh 5% hydrochloric acid hal mar, ku dhaq biyo hal mar, ku qallaji magnesium sulfate anhydrous, iyo uumi dareeraha organic hoos cadaadiska hooseeyo si aad u hesho 2 chloro-5-nitropyridine.
