Taw qhia

Gamma octinolactone tseem hu ua 2-octinolactone. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj, thiab cov ntaub ntawv kev nyab xeeb ntawm gamma octinolactone:

Zoo:

- Cov tsos: cov kua tsis muaj xim

- Solubility: Miscible nrog ntau cov kuab tshuaj organic

- Flammability: yog cov kua ua kua

Siv:

- Nws kuj tseem siv tau los ua cov khoom siv hauv cov txheej txheem, tshuaj ntxuav, thiab cov tshuaj tsw qab.

Txoj kev:

Agamagnyllactone feem ntau yog npaj los ntawm esterification. Ib txoj kev npaj siv feem ntau yog esterify caprylic acid (C8H16O2) thiab isopropanol (C3H7OH) nyob rau hauv qhov kev txiav txim ntawm cov kua qaub catalyst los tsim gamma octyrolactone.

Cov ntaub ntawv kev nyab xeeb:

- Glutaminolactone yog cov kua nplaum nplaum thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov kub thiab txias.

- Khaws qhov cua kom zoo thaum siv gamma octinolactone thiab tsis txhob nqus nws cov vapors.

- Kev raug gamma octinolactone tuaj yeem ua rau qhov muag thiab tawv nqaij khaus, yog li hnav hnab looj tes tiv thaiv thiab tsom iav thaum tuav cov txheej txheem.

- Thaum siv thiab khaws cia, yuav tsum tau saib xyuas kom tsis txhob muaj oxidants muaj zog thiab muaj zog acids kom tsis txhob muaj tshuaj lom neeg.

- Cov txheej txheem tsim nyog thiab cov txheej txheem ua haujlwm nyab xeeb yuav tsum tau ua raws thaum tuav gamma octinolactone kom ntseeg tau tias tus kheej muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
