Taw qhia
Butyl butyrate 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 butyrate:
Zoo:
- Cov tsos mob: Butyl butyrate yog cov xim tsis muaj xim rau cov kua daj daj nrog cov ntxhiab tsw qab.
- Solubility: Butyl butyrate tuaj yeem soluble hauv cawv, ethers thiab organic solvents, thiab me ntsis soluble hauv dej.
Siv:
- Cov kuab tshuaj: Butyl butyrate tuaj yeem siv los ua cov kuab tshuaj organic hauv cov txheej txheem, inks, adhesives, thiab lwm yam.
- Chemical synthesis: Butyl butyrate kuj tseem siv tau los ua ib qho nruab nrab ntawm cov tshuaj synthesis rau cov synthesis ntawm esters, ethers, etherketones thiab lwm yam organic compounds.
Txoj kev:
Butyl butyrate tuaj yeem tsim los ntawm cov tshuaj tiv thaiv acid-catalyzed:
Hauv cov khoom siv tshuaj tiv thaiv tsim nyog, butyric acid thiab butanol ntxiv rau cov hlab ntsha hauv cov tshuaj tiv thaiv hauv ib qho kev faib ua feem.
Ntxiv cov catalysts (xws li sulfuric acid, phosphoric acid, thiab lwm yam).
Tshav kub cov tshuaj tiv thaiv sib tov thiab tswj qhov kub kom haum, feem ntau 60-80 ° C.
Tom qab qee lub sijhawm, cov tshuaj tiv thaiv dhau lawm, thiab cov khoom tuaj yeem tau txais los ntawm distillation lossis lwm yam kev sib cais thiab kev ua kom huv.
Cov ntaub ntawv kev nyab xeeb:
- Butyl butyrate yog ib yam khoom muaj toxicity tsawg thiab feem ntau tsis muaj teeb meem rau tib neeg raws li kev siv ib txwm muaj.
- Thaum khaws cia thiab tuav, tsis txhob sib cuag nrog oxidants, muaj zog acids, muaj zog alkalis thiab lwm yam khoom kom tsis txhob muaj kev phom sij txaus ntshai.
- Hauv kev tsim khoom thiab kev siv, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem kev ua haujlwm nyab xeeb thiab hnav cov cuab yeej tiv thaiv tsim nyog kom ntseeg tau tias kev siv nyab xeeb.
