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

sumo 2,3, 5-trichloropyridine izere yero yakasimba uye yakakosha kemikari yepakati. 2,3,5-trichloropyridine inopindirana nealkali metal hydroxide kugadzirira 3,5-dichloro-2-pyridine phenol, iyo inokosha mbishi yekugadzirwa kwezvipembenene zvezvipembenene uye herbicide oxaloether. 2,3, 5-trichloropyridine inogona zvakare kuvezwa zvakare fluorinated kuti igadzire 2, 3-difluoro-5-chloropyridine, inova ndiyo yekutanga mbishi yekugadzirwa kweherbicide alkynurate.
kugadzirira 60g yemethanol yakawedzerwa kune 1000mL ine-muromo flask, 100g
2,3,5,6-tetrachloropyridine uye 31.7g ye hydrazine hydrate yakawedzerwa, tembiricha yakasimudzwa kusvika 60-65 ℃, maitiro ekuchengetedza kupisa akaitwa kweanenge maawa maviri, maitiro akapera, tembiricha yakaderedzwa kusvika 0-5 ℃, tembiricha yakaderedzwa kusvika paawa imwe, yakasimba yakasefa, uye yakasimba yaive 2,3, 5-trichlor6-hydrazinyl pyridine hydrate yakaomeswa kuti iwane 101.6g yemuchena yakasimba ine 96% yezvibereko uye 98.5% zvinyorwa. Wedzera 100g
2,3,5-trichloro 6-hydrazinyl pyridine hydrate, 50g ye5% sodium hydroxide aqueous solution kusvika 1000ml yebhodhoro remuromo mina, simudza tembiricha kusvika 70-75 ℃, wedzera 387.6g ye10% sodium hypochlorite aqueous solution dropwise, chengetedza tembiricha iri pa70-75 ℃, ita kweawa imwe, pedza reaction, inotonhorera kusvika 5-10 ℃, kurunga kweawa imwe, sefa kuti uwane 2,3, iyo isina kuchena 5-trichloropyridine inonyungudutswa pasi pekumanikidzwa kwakaderedzwa kuti uwane chigadzirwa, chiri chero yero yakasimba ine goho re95% uye a zviri mukati 98%.
