Siv:

- yog dav siv los ua ib qho nruab nrab hauv cov organic synthesis thiab tuaj yeem siv los ua ke lwm cov organic sib txuas.

-Nws tseem tuaj yeem siv los ua cov khoom pib rau kev siv tshuaj yeeb tshuaj, tshuaj tua kab thiab tshuaj tua kab.

Txoj Kev Npaj:

-los yog tuaj yeem npaj los ntawm cov tshuaj tiv thaiv halogenation ntawm pyridine. Ua ntej, pyridine thiab acetic acid tau txais cov tshuaj chlorination los tsim 2-chloropyridine. Tom qab ntawd 2-chloropyridine hloov mus rau 2-chloro-3-fluoropyridine los ntawm cov tshuaj fluorination. Thaum kawg, 2-chloro-3-fluoropyridine tau methylated siv cov tshuaj tiv thaiv methylation.

Cov ntaub ntawv kev nyab xeeb:

- yog ib qho tshuaj lom neeg uas ua rau khaus qhov muag thiab tawv nqaij.

-Thaum siv thiab tuav, yuav tsum muaj kev ntsuas kev nyab xeeb tsim nyog, suav nrog hnav tsom iav thiab hnab looj tes.

-Tsis txhob nqus cov vapor ntawm qhov sib xyaw thiab xyuas kom meej tias nws tau ua haujlwm nyob rau hauv qhov chaw zoo-ventilated.

-Thaum khaws cia thiab tuav, kom deb ntawm hluav taws thiab oxidizing cov neeg ua haujlwm kom tsis txhob muaj hluav taws kub thiab tawg.

-Thaum siv, yuav tsum tau saib xyuas kom ua raws li cov txheej txheem kev nyab xeeb thiab kev tswj hwm.
