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

Intangiriro 2,3, 5-trichloropyridine ni umuhondo wijimye wijimye kandi ningirakamaro hagati yimiti. 2,3,5-trichloropyridine ifata hamwe na hydroxide ya alkali yicyuma kugirango itegure fenol 3,5-dichloro-2-pyridine, ikaba ari ibikoresho byingenzi byifashishwa muguhuza udukoko twica udukoko hamwe na herbicide oxaloether. 2,3, 5-trichloropyridine irashobora kandi guhindurwamo fluor kugirango ikomatanye 2, 3-difluoro-5-chloropyridine, akaba aribikoresho fatizo byibanze bya synthesis ya alkynurate ya herbicide.
kwitegura 60g ya methanol yongewe kuri 1000mL flask yiminwa ine, 100g
Hiyongereyeho 2,3,5,6-tetrachloropyridine na 31.7g ya hydratine hydratine, ubushyuhe bwazamutse bugera kuri 60-65 ℃, uburyo bwo kubungabunga ubushyuhe bwakozwe mu gihe cy’amasaha agera kuri 2, reaction irarangira, ubushyuhe buramanuka kugeza 0-5. bikomeye hamwe n'umusaruro wa 96% nibirimo 98.5%. Ongeramo 100g
2,3,5-trichloro 6-hydrazinyl pyridine hydrat, 50g ya 5% ya hydroxide ya hydroxide ya sodium ya 1000ml kumacupa yiminwa ine, kuzamura ubushyuhe kugera kuri 70-75 ℃, ongeramo 387,6g ya 10% ya sodium hypochlorite yumuti wamazi, komeza ubushyuhe kuri 70-75 ℃, reba isaha 1, urangize reaction, ukonje kugeza 5-10 ℃, koga kumasaha 1, kuyungurura kugirango ubone 2,3, igikonjo 5-trichloropyridine itandukanijwe nigitutu cyagabanutse kugirango ibone ibicuruzwa, bikaba umuhondo wijimye wijimye ufite umusaruro wa 95% nibirimo 98%.
