2 3 5-Trichloropyridine (CAS# 16063-70-0) Macluumaadka
| hordhac | 2,3, 5-trichloropyridine waa jaale khafiif ah oo adag iyo dhexdhexaad kiimiko ah oo muhiim ah. 2,3,5-trichloropyridine waxay la falgashaa birta alkali hydroxide si ay u diyaariso 3,5-dichloro-2-pyridine phenol, taas oo ah walxo muhiim ah oo ceeriin ah oo loogu talagalay isku dhafka cayayaanka cayayaanka iyo oxaloether herbicide. 2,3, 5-trichloropyridine sidoo kale waa la sii kordhin karaa si loo soo saaro 2, 3-difluoro-5-chloropyridine, taas oo ah alaabta ceeriin ee aasaasiga ah ee isku dhafka alkynurate herbicide. |
| diyaarinta | 60g oo methanol ah ayaa lagu daray 1000mL galaas afar af ah, 100g. 2,3,5,6-tetrachloropyridine iyo 31.7g of hydrazine hydrate ayaa lagu daray, heerkulka ayaa kor loo qaaday ilaa 60-65 ℃, falcelinta ilaalinta kulaylka ayaa la fuliyay qiyaastii 2 saacadood, falcelinta ayaa la dhammeeyey, heerkulka ayaa hoos loo dhigay 0-5 ℃, heerkulka ayaa hoos loo dhigay ilaa 1 saac, adag ayaa la sifeeyay, oo adag wuxuu ahaa 2,3; 5-trichlor6-hydrazinyl pyridine hydrate waa la qalajiyey si loo helo 101.6g oo cad cad oo leh 96% dhalo iyo 98.5% ka kooban. Ku dar 100g 2,3,5-trichloro 6-hydrazinyl pyridine hydrate, 50g of 5% sodium hydroxide xal aqueous ilaa 1000ml dhalo afar af ah, kor u heerkulka ilaa 70-75 ℃, ku dar 387.6g of 10% sodium hypochlorite xal aqueous dropwise, heerkulka ku hay 70-75 ℃, ka fal celi 1 saac, dhammaad falcelinta, qabow ilaa 5-10 ℃, walaaq 1 saac, filter si aad u hesho 2,3, cayriin 5-trichloropyridine waxaa la distilled hoos cadaadis hoos u ah si aad u hesho alaabta, taas oo ah huruud khafiif ah oo leh dhalidda 95% iyo ka kooban 98%. |
