Taw qhia

Ethyl valerate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm ethyl valerate:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Ntsim: Cawv aroma nrog txiv hmab txiv ntoo

- Ignition point: txog 35 degrees Celsius

- Solubility: soluble nyob rau hauv ethanol, ethers thiab organic solvents, insoluble nyob rau hauv dej

 

Siv:

- Kev siv hluav taws xob: Raws li cov kuab tshuaj, nws tuaj yeem siv rau hauv kev lag luam tshuaj xws li xim, inks, kua nplaum, thiab lwm yam.

 

Txoj kev:

Ethyl valerate tuaj yeem npaj tau los ntawm esterification ntawm valeric acid thiab ethanol. Nyob rau hauv cov tshuaj tiv thaiv, valeric acid thiab ethanol yog ntxiv rau cov tshuaj tiv thaiv lub raj mis, thiab acidic catalysts xws li sulfuric acid los yog hydrochloric acid yog ntxiv los nqa tawm cov tshuaj tiv thaiv esterification.

 

Cov ntaub ntawv kev nyab xeeb:

- Ethyl valerate yog cov kua ua kua, yog li nws yuav tsum tau muab cia kom deb ntawm qhov hluav taws kub thiab kub, thiab khaws cia rau hauv qhov chaw muaj cua zoo.

- Kev raug ethyl valerate tuaj yeem ua rau qhov muag thiab tawv nqaij khaus, yog li hnav hnab looj tes tiv thaiv thiab tiv thaiv qhov muag thaum siv.

-Thaum qhov nqus tau los yog nqus tau, txav tus neeg mob tam sim ntawd mus rau huab cua ntshiab thiab nrhiav kev kho mob tam sim yog tias tus mob hnyav.

- Thaum khaws cia, khaws lub ntim kom nruj kom deb ntawm oxidants thiab acids kom tsis txhob muaj xwm txheej.
