Taw qhia

4-nitrobenzyl cawv. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 4-nitrobenzyl cawv:

 

Zoo:

- 4-Nitrobenzyl cawv yog cov xim tsis muaj xim crystalline nrog cov ntxhiab tsw ntxhiab tsw.

- Nws ruaj khov ntawm chav tsev kub thiab siab, tab sis nws yuav ua rau tawg thaum raug tshav kub, kev co, kev sib txhuam lossis kev sib cuag nrog lwm yam khoom.

- Nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li cawv, ethers, thiab chlorinated hydrocarbons, thiab me ntsis soluble hauv dej.

 

Siv:

- 4-nitrobenzyl cawv yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab yog dav siv nyob rau hauv kev npaj ntawm ntau yam tshuaj.

 

Txoj kev:

- 4-Nitrobenzyl cawv tuaj yeem tau los ntawm kev txo cov tshuaj p-nitrobenzene nrog sodium hydroxide hydrate. Muaj ntau yam kev mob tshwj xeeb thiab txoj hauv kev rau cov tshuaj tiv thaiv, uas feem ntau yog ua raws li acidic lossis alkaline tej yam kev mob.

 

Cov ntaub ntawv kev nyab xeeb:

- 4-Nitrobenzyl cawv yog tawg thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab kub kub.

- Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv thaum ua haujlwm.

- Kev ua raws cai nruj raws li cov kev coj ua kom nyab xeeb thiab cov kev cai yuav tsum tau ua raws li kev khaws cia thiab tuav.

- Ua tib zoo saib xyuas kev tiv thaiv ib puag ncig thiab ua raws li cov cai thiab cov qauv tsim nyog thaum siv lossis pov tseg.
