Taw qhia

Cov khoom ntawm p-ethylbenzoic acid: Nws yog cov kua tsis muaj xim lossis daj daj nrog cov ntxhiab tsw tshwj xeeb. P-ethylbenzoic acid yog soluble hauv cawv thiab ether thiab insoluble hauv dej.

 

Kev siv p-ethylbenzoic acid: Ethylbenzoic acid kuj tseem siv tau rau hauv kev npaj cov txheej, inks, thiab dyes.

 

Txoj kev npaj ntawm p-ethylbenzoic acid:

Kev npaj ntawm p-ethylbenzoic acid feem ntau yog ua los ntawm catalytic oxidation ntawm ethylbenzene nrog oxygen. Hloov pauv hlau oxides, xws li molybdate catalysts, feem ntau yog siv rau catalysts. Cov tshuaj tiv thaiv tshwm sim ntawm qhov kub thiab txias kom tsim p-ethylbenzoic acid.

 

Cov ntaub ntawv kev nyab xeeb rau ethylbenzoic acid:

Ethylbenzoic acid muaj qhov ua rau khaus ntawm qhov muag thiab tawv nqaij, thiab yuav tsum tau yaug nrog dej kom ntau rau lub sijhawm thaum sib cuag. Cov khoom siv tiv thaiv tus kheej tsim nyog xws li tsom iav thiab hnab looj tes yuav tsum hnav thaum ua haujlwm. Ethylbenzoic acid yuav tsum muab cia rau hauv ib lub thawv airtight, kom deb ntawm ignition thiab oxidants. Yog tias tsim nyog, nws yuav tsum tau ua haujlwm nyob rau hauv qhov chaw zoo-ventilated.
