Txoj kev:

Kev npaj cov kua qaub tuaj yeem ua tau los ntawm cov kauj ruam hauv qab no:

1. 2-Fluoro-4-nitrobenzene (2-fluoroo-4-nitrobenzene) yog reacted nrog bromoacetic acid (bromoacetic acid) kom tau 2-bromoacetic acid ester (bromoacetic acid ester).

2. Ua kua qaub bromide ntsev nrog hydrolysis tus neeg sawv cev los yog kho nrog anion pauv resin kom tau cov kua qaub.

Cov ntaub ntawv kev nyab xeeb:

-los yog kua qaub yog cov organic compound, thiab kev tiv thaiv tsim nyog yuav tsum tau ua thaum raug, xws li hnav cov hnab looj tes tiv thaiv, tsom iav, thiab lwm yam.

-Nws yuav ua rau khaus thiab ua rau lub qhov muag, tawv nqaij thiab ua pa. Zam kev sib cuag ncaj qha.

-Thaum siv thiab khaws cia, yuav tsum tau saib xyuas kom tsis txhob muaj hluav taws kub thiab tsis txhob kov cov oxidants.

-Yog noj los yog nqus tau, nrhiav kev kho mob tam sim ntawd.
