Taw qhia
Butyl isovalerate, tseem hu ua n-butyl isovalerate, yog ib qho ester compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm butyl isovalerate:
Zoo:
Butyl isovalerate yog cov kua tsis muaj xim, pob tshab nrog cov txiv hmab txiv ntoo zoo li aroma. Nws yog insoluble hauv dej thiab soluble hauv cawv thiab ether solvents.
Siv:
Butyl isovalerate feem ntau yog siv los ua cov kuab tshuaj thiab diluent hauv kev lag luam. Nws tuaj yeem siv rau hauv cov txheej txheem tsim cov xim, coatings, glues, detergents, thiab lwm yam.
Siv los ua cov khoom xyaw hauv kua nplaum, nws tuaj yeem txhawb nqa cov nplaum nplaum.
Txoj kev:
Butyl isovalerate feem ntau tau txais los ntawm cov tshuaj tiv thaiv ntawm n-butanol nrog isovaleric acid. Cov tshuaj tiv thaiv feem ntau yog ua nyob rau hauv acid-catalyzed tej yam kev mob. Sib tov n-butanol nrog isovaleric acid massage piv, ntxiv me me ntawm acid catalyst, feem ntau siv catalyst yog sulfuric acid los yog phosphoric acid. Cov tshuaj tiv thaiv sib tov yog ces rhuab kom cov tshuaj tiv thaiv mus ntxiv. Los ntawm kev sib cais thiab kev ua kom huv, cov khoom ntshiab butyl isovalerate tau txais.
Cov ntaub ntawv kev nyab xeeb:
Butyl isovalerate tuaj yeem ua rau tawv nqaij, qhov muag, thiab ua pa. Nws tuaj yeem ua rau khaus, liab, thiab mob thaum nws los rau ntawm daim tawv nqaij. Kev nqus pa ntawm cov vapors uas muaj siab ntawm butyl isovalerate tuaj yeem ua rau ua pa ua pa thiab mob taub hau. Yog tias nqos tau, nws tuaj yeem ua rau cov tsos mob xws li ntuav, raws plab, thiab mob plab. Thaum siv butyl isovalerate, cov hnab looj tes tiv thaiv, tsom iav, thiab cov qhov ncauj qhov ntswg tiv thaiv yuav tsum tau hnav kom muaj kev nyab xeeb. Thaum khaws cia thiab thauj, tsis txhob sib cuag nrog cov nplaim taws qhib thiab qhov kub thiab txias. Yog tias tsis tsim nyog, tawm ntawm qhov chaw sai sai thiab nrhiav kev kho mob.
