Taw qhia
2-phenylethyl formate. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
2-phenylethyl formate yog cov kua tsis muaj xim nrog lub qab zib, fruity aroma. Nws yog insoluble hauv dej thiab me ntsis soluble hauv ethanol thiab ether.
Siv:
2-phenylethyl formate yog siv dav hauv kev lag luam tshuaj tsw qab thiab tsw, thiab feem ntau siv los npaj cov txiv hmab txiv ntoo flavors, floral flavors thiab flavors. Nws cov txiv hmab txiv ntoo tsw yog feem ntau siv hauv cov txiv hmab txiv ntoo-flavored dej qab zib, khoom qab zib, zom cov pos hniav, naj hoom thiab lwm yam khoom.
Txoj kev:
2-phenylethyl formate tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm formic acid thiab phenylethanol. Cov tshuaj tiv thaiv feem ntau yog nyob rau hauv acidic tej yam kev mob, thiab ib tug catalyst (xws li acetic acid, thiab lwm yam) yog ntxiv rau cov condensation cov tshuaj tiv thaiv. Cov khoom yog distilled thiab purified kom tau cov ntshiab forme-2-phenylethyl ester.
Cov ntaub ntawv kev nyab xeeb:
2-phenylethyl formate yog tshuaj lom thiab khaus rau qee yam. Yog tias nws nkag mus rau ntawm daim tawv nqaij thiab qhov muag, nws tuaj yeem ua rau khaus lossis khaus. Kev nqus cov pa ntau dhau ntawm forme-2-phenylethyl vapor tuaj yeem ua rau cov tsos mob xws li ua pa ua pa thiab kiv taub hau. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab daim npog ntsej muag yuav tsum hnav thaum siv. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tsis txhob sib cuag nrog cov oxidant thaum lub sij hawm cia, thiab tsis txhob muaj qhov kub thiab qhov kub thiab qhov hluav taws kub.
