Taw qhia

Ethyl benzoate) yog cov organic compound uas yog cov kua tsis muaj xim ntawm chav tsev kub. Cov hauv qab no yog cov ntaub ntawv hais txog cov khoom, kev siv, kev npaj thiab kev nyab xeeb ntawm ethyl benzoate:

 

Zoo:

Nws muaj cov ntxhiab tsw ntxhiab thiab yog volatile.

Soluble hauv cov kuab tshuaj organic xws li ethanol, ether, thiab lwm yam, insoluble hauv dej.

 

Siv:

Ethyl benzoate feem ntau yog siv los ua cov kuab tshuaj hauv kev lag luam xws li pleev xim, kua nplaum thiab tshuaj ntsiav tshuaj.

 

Txoj kev:

Kev npaj ntawm ethyl benzoate feem ntau yog ua los ntawm esterification. Cov txheej txheem tshwj xeeb suav nrog kev siv benzoic acid thiab ethanol ua cov khoom siv raw, thiab nyob rau hauv muaj cov kua qaub catalyst, cov tshuaj tiv thaiv yog nqa tawm ntawm qhov tsim nyog kub thiab siab kom tau ethyl benzoate.

 

Cov ntaub ntawv kev nyab xeeb:

Ethyl benzoate yog irritating thiab volatile thiab yuav tsum tau zam nyob rau hauv kev sib cuag nrog cov tawv nqaij thiab ob lub qhov muag.

Kev ceev faj yuav tsum tau them rau qhov cua thaum lub sijhawm kho kom tsis txhob nqus cov pa los yog tsim hluav taws xob.

Thaum khaws cia, cia kom deb ntawm qhov chaw tshav kub thiab qhib nplaim taws, thiab kaw lub thawv kom nruj.

Yog tias nqus tau los yog kov tsis tau, mus rau qhov chaw muaj cua kom huv si lossis nrhiav kev kho mob raws sijhawm.
