2-chloro-5-chloromethyl pyridine (CCMP) waa dhexdhexaad dawo muhiim ah iyo dhexdhexaad muhiim ah oo loogu talagalay isku dhafka sunta cayayaanka ee pyridine sida imidacloprid, acetamiprid, fluazinam, iwm.
Waxaa jira habab badan oo isku dhafan oo ah 2-chloro-5-chloromethyl pyridine.Waqtigan xaadirka ah, 2-chloro-5-methylpyridine waxaa loo isticmaalaa sida alaabta ceeriin ee warshadaha, taas oo ah, 2-chloro-5-methylpyridine waxaa koloriin ku jira 2-chloro-5-methylpyridine iyada oo ay jirto kiciye si loo helo 2-chloro -5-chloromethyl pyridine.2-chloro-5-methylpyridine iyo dareeraha ayaa lagu daray kiliyaha koloriinta, kicinta ayaa lagu daray, gaaska chlorine-ka ayaa lagu duray falcelinta hoos timaada xaalada reflux.Falcelinta ka dib, cadaadiska atmospheric ee ugu horreeya waa la kala diri, ka dibna jajabkii hore waxaa laga saaray faakuum ku jira kiliyaha distillation, iyo 2-chloro-5-methylpyridine ayaa laga helay gunta hoose ee kiliyaha.Marka lagu daro , waxaa jira wadooyin kala duwan oo kala duwan oo loo isticmaalo niacin sida alaabta ceeriin, 3-methylpyridine sida alaabta ceeriin, 2-chloro-5-trichloromethyl pyridine sida alaabta ceeriin.Tilmaamaha caadiga ah ee hababkani waa samaynta giraanta pyridine oo ay ku xigto dhamaystirka chloromethylation.Waddo kale oo ay soo saartay Shirkadda Rayleigh ee Maraykanka (ReillyIndustriesInc.) waxay qaadataa cyclopentadiene iyo propanal sida bilawga alaabta ceeriin si ay si toos ah u cyclosynthesize 2-chloro-5-chloromethyl pyridine, nadiifinta alaabadu waa sida ugu sareysa 95%, iyada oo aan lahayn isomer 2 -chloro-3-chloromethyl pyridine.
25Kg/fuusto;Baakad si waafaqsan shuruudaha macmiilka.
Alaabtan waa in lagu kaydiyaa weel xidhan oo lagu hayaa meel qabow oo qalalan inta lagu jiro kaydinta iyo gaadiidka.Ha ku darin oksaydhiyeyaasha gaadiidka iyo kaydinta.
