Txoj Kev Npaj:

Nws tuaj yeem ua ke los ntawm cov kauj ruam hauv qab no: br> 1. Ua ntej, raws li qhov tsim nyog cov tshuaj tiv thaiv, methyl bromide thiab p-nitrobenzene sulfonamide yog reacted los tsim methyl ester.

2. Tom qab ntawd, methyl ester yog reacted nrog alkaline tov kom tau ntsev.

Cov ntaub ntawv kev nyab xeeb:

-yuav tsum khaws cia rau hauv qhov chaw qhuav, qhov cua zoo, thiab tsis txhob raug tshav ntuj ncaj qha.

-Thaum ua haujlwm, tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Yog tias kis tau, yaug tam sim nrog dej ntau thiab nrhiav kev kho mob.

- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb thiab khaub ncaws tiv thaiv thaum tuav cov khoom sib xyaw.

-Tsis txhob sib tov cov tshuaj no nrog cov oxidants muaj zog thiab muaj zog acids, vim nws yuav ua rau muaj kev phom sij txaus ntshai.

- Ua ntej siv lossis tuav cov khoom sib xyaw, cov lus qhia kev nyab xeeb uas muab los ntawm tus neeg muag khoom yuav tsum tau nyeem kom zoo.
