Taw qhia
Isobutyrate yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm isobutyrate:
Zoo:
Cov tsos mob: Isobutyl butyrate yog cov kua uas tsis muaj xim pob tshab nrog lub aroma tshwj xeeb.
Qhov ceev: 0.87 g / cm3.
Solubility: Isobutyrate tuaj yeem yaj hauv ntau cov kuab tshuaj organic xws li ethanol, ethers thiab benzene cov kuab tshuaj.
Siv:
Daim ntawv thov kev ua liaj ua teb: Isobutyl butyrate kuj tseem siv los ua tus tswj kev loj hlob ntawm cov nroj tsuag los txhawb cov nroj tsuag kev loj hlob thiab txiv hmab txiv ntoo ripening.
Txoj kev:
Isobutyl butyrate tuaj yeem tau txais los ntawm reacting isobutanol nrog butyric acid. Cov tshuaj tiv thaiv feem ntau yog ua nyob rau hauv lub xub ntiag ntawm acid catalysts, thiab feem ntau siv acid catalysts yog sulfuric acid, txhuas chloride, thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb:
Isobutyl butyrate yog cov khoom siv hluav taws xob thiab yuav tsum tau zam los ntawm kev sib cuag nrog cov nplaim taws qhib thiab kub siab.
Tsis txhob nqus cov vapors lossis kua ntawm isobutyrate thiab tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
Yog tias nqus tau los yog raug rau isobutyrate, txav tam sim ntawd mus rau qhov chaw uas muaj cua zoo thiab yaug qhov chaw cuam tshuam nrog dej huv. Yog tias koj tsis xis nyob, koj yuav tsum nrhiav kev kho mob tam sim ntawd.
