Taw qhia

2-Chloropyridine-6-carboxylic acid, tseem hu ua 2-Chloro-6-pyridinecarboxylic acid.

 

Zoo:

2-Chloropyridine-6-carboxylic acid yog dawb crystalline khoom nrog ib tug tshwj xeeb tsw. Nws yog soluble hauv cawv, ketone thiab ether solvents thiab me ntsis soluble hauv dej.

 

Siv:

2-Chloropyridine-6-carboxylic acid tuaj yeem siv los ua qhov nruab nrab hauv kev sib txuas ntawm cov organic sib txuas.

 

Txoj kev:

Kev npaj ntawm 2-chloropyridine-6-carboxylic acid tuaj yeem tau txais los ntawm kev ua haujlwm 2-chloropyridine nrog cov tshuaj chlorine nyob rau hauv lub xub ntiag ntawm cov cawv catalyst. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:

Nyob rau hauv qhov xwm txheej ntawm qhov kub thiab txias, 2-chloropyridine yog reacted nrog chlorine, thiab cov khoom (2-chloropyridine-6-carboxylic acid) tau txais tom qab cov tshuaj tiv thaiv.

 

Cov ntaub ntawv kev nyab xeeb:

2-Chloropyridine-6-carboxylic acid feem ntau muaj kev nyab xeeb nyob rau hauv ib txwm ua haujlwm, tab sis tseem yuav tsum tau ceev faj. Thaum siv, tsis txhob sib cuag nrog daim tawv nqaij thiab ob lub qhov muag, thiab xyuas kom meej tias qhov kev ua haujlwm tau ua nyob rau hauv qhov chaw muaj cua zoo. Thaum muaj xwm txheej, yaug tam sim nrog dej ntau thiab nrhiav kev kho mob.

Thaum siv thiab tuav cov tshuaj, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li kev soj ntsuam thiab kev tiv thaiv tus kheej kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
