3,5-Dimethyl-4-nitrobenzoic acid (CAS # 3095-38-3)

Taw qhia

4-Nitro-3,5-dimethylbenzoic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

Zoo:

- 4-Nitro-3,5-dimethylbenzoic acid yog cov xim tsis muaj xim crystalline nrog ib qho tsw qab.

- Nws yog qhov ruaj khov ntawm chav tsev kub, tab sis kev tawg tuaj yeem tshwm sim ntawm qhov kub thiab txias, hauv lub teeb, lossis thaum raug hluav taws kub.

- Nws yuav luag insoluble hauv dej, tab sis soluble nyob rau hauv cov organic solvents xws li ethanol, ethers, thiab chlorinated hydrocarbons.

Siv:

- 4-nitro-3,5-dimethylbenzoic acid feem ntau yog siv los ua ib qho nruab nrab ntawm dyes thiab cov khoom siv raw rau kev tsim cov pigments.

Txoj kev:

- 4-Nitro-3,5-dimethylbenzoic acid tuaj yeem tau los ntawm nitrification ntawm p-toluene. Nitrification cov tshuaj tiv thaiv feem ntau siv cov sib xyaw ntawm nitric acid thiab sulfuric acid ua tus neeg sawv cev nitrifying.

- Txoj kev npaj tshwj xeeb yog feem ntau: toluene yog tov nrog nitric acid thiab sulfuric acid, rhuab rau cov tshuaj tiv thaiv, thiab ces crystallized thiab purified.

Cov ntaub ntawv kev nyab xeeb:

- 4-Nitro-3,5-dimethylbenzoic acid yog irritating thiab corrosive thiab yuav tsum tau zam nyob rau hauv kev sib cuag nrog daim tawv nqaij thiab ob lub qhov muag.

- Thaum tuav cov khoom sib xyaw no, hnav hnab looj tes tiv thaiv, lub tshuab ua pa, thiab tsom iav tiv thaiv kom tsis txhob nqus pa lossis nkag mus rau ntawm daim tawv nqaij.

- Thaum khaws cia thiab tuav, tsis txhob sib cuag nrog cov oxidants, ignition qhov chaw thiab cov ntaub ntawv flammable kom tsis txhob muaj hluav taws kub los yog tawg.

-Thaum noj tshuaj tsis haum lossis nqus tau, nrhiav kev kho mob tam sim ntawd thiab nthuav tawm cov ntaub ntawv kev nyab xeeb ntawm cov khoom rau koj tus kws kho mob.
