2 3 5-Trichloropyridine (CAS# 16063-70-0) Zambiri

mawu oyamba 2,3, 5-trichloropyridine ndi cholimba chachikasu chopepuka komanso chofunikira kwambiri chapakatikati. 2,3,5-trichloropyridine imakhudzidwa ndi zitsulo zamchere hydroxide kukonzekera 3,5-dichloro-2-pyridine phenol, yomwe ndi yofunika kwambiri popanga tizilombo toyambitsa matenda ndi herbicide oxaloether. 2,3, 5-trichloropyridine nawonso fluorinated kuti synthesize 2, 3-difluoro-5-chloropyridine, amene ndi zofunika zopangira kwa synthesis wa herbicide alkynurate.
kukonzekera 60g ya methanol inawonjezeredwa ku 1000mL yapakamwa inayi botolo, 100g
2,3,5,6-tetrachloropyridine ndi 31.7g ya hydrazine hydrate adawonjezeredwa, kutentha kunakwezedwa mpaka 60-65 ℃, zomwe zimateteza kutentha kunachitika pafupifupi maola awiri, zomwe zidatha, kutentha kunatsitsidwa. 0-5 ℃, kutentha kunatsitsidwa mpaka 1 ora, cholimba chinasefedwa, ndipo cholimba chinali 2,3, 5-trichlor6-hydrazinyl pyridine hydrate inauma kuti ipeze 101.6g yoyera yoyera ndi 96% zokolola ndi 98.5% zokhutira. Onjezani 100g
2,3,5-trichloro 6-hydrazinyl pyridine hydrate, 50g ya 5% sodium hydroxide amadzimadzi njira 1000ml wa botolo pakamwa zinayi, kukweza kutentha kwa 70-75 ℃, kuwonjezera 387.6g 10% sodium hypochlorite amadzimadzi njira dropwise, sungani kutentha kwa 70-75 ℃, chitani kwa ola limodzi, kutsiriza momwe, kuzizira mpaka 5-10 ℃, kusonkhezera kwa ola limodzi, fyuluta kuti ipeze 2,3, 5-trichloropyridine yosakanizidwa imasungunuka pansi pa kupanikizika kochepa kuti ipeze mankhwala, omwe ndi olimba achikasu ndi zokolola za 95% ndi za 98%.
