Taw qhia

Butyl propionate (tseem hu ua propyl butyrate) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm butyl propionate:

 

Zoo:

- Cov tsos: cov kua tsis muaj xim.

- Solubility: soluble nyob rau hauv cawv thiab ether solvents, insoluble nyob rau hauv dej.

- Nplej: muaj txiv hmab txiv ntoo zoo li aroma.

 

Siv:

- Cov ntawv thov kev lag luam: Butyl propionate yog cov kuab tshuaj tseem ceeb uas tau siv dav hauv kev lag luam xws li pleev xim, txheej, inks, nplaum, thiab tshuaj ntxuav.

 

Txoj kev:

Butyl propionate feem ntau yog npaj los ntawm esterification, uas yuav tsum tau cov tshuaj tiv thaiv ntawm propionic acid thiab butanol, thiab feem ntau siv catalysts xws li sulfuric acid, tolene sulfonic acid, los yog alkyd acid.

 

Cov ntaub ntawv kev nyab xeeb:

- Vapor ntawm butyl propionate tuaj yeem ua rau qhov muag thiab ua pa ua pa, yog li ua tib zoo saib xyuas qhov cua thaum siv nws.

- Tsis txhob cuam tshuam nrog butyl propionate ntev, uas yuav ua rau khaus thiab dryness ntawm daim tawv nqaij.

- Thaum tuav thiab khaws cia, ua raws li cov txheej txheem tswj kev nyab xeeb ntawm cov tshuaj muaj feem xyuam, siv kev ceev faj kom tsim nyog, thiab tsis txhob sib cuag nrog cov khoom siv hluav taws xob.
