Taw qhia
Phenylethyl phenylacetate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm phenylethyl phenylacetate:
Zoo:
- Cov tsos mob: Phenylethyl phenylacetate yog xim tsis muaj xim rau yellowish kua lossis crystalline khoom.
- Solubility: Phenylethyl phenylacetate yog soluble hauv cov kuab tshuaj organic xws li ethanol, ether thiab dimethylformamide.
Siv:
- Kev siv: Phenylethyl phenylacetate feem ntau yog siv los ua cov kuab tshuaj organic thiab yog siv dav hauv kev lag luam xws li coatings, inks, adhesives thiab tshuaj ntxuav.
- Lwm yam kev siv: Phenylethyl phenylacetate kuj siv tau rau hauv kev npaj cov txuj lom, flavorings thiab hluavtaws tsw.
Txoj kev:
Ib txoj kev siv feem ntau rau kev npaj phenylethyl phenylacetate yog ua los ntawm anhydride esterification cov tshuaj tiv thaiv. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:
Dissolve phenylacetic acid thiab sodium phenylacetate hauv benzene lossis xylene cov kuab tshuaj.
Anhydrides (piv txwv li, anhydrides) yog ntxiv los ua cov tshuaj esterifying, xws li acetic anhydride.
Nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst, cov tshuaj tiv thaiv sib tov yog rhuab.
Tom qab cov tshuaj tiv thaiv tiav lawm, phenylethyl phenylacetate tau txais los ntawm distillation thiab lwm txoj kev.
Cov ntaub ntawv kev nyab xeeb:
- Cov vapor ntawm phenylethyl phenylacetate tuaj yeem ua rau muaj ntxhiab tsw uas tuaj yeem ua rau khaus qhov muag, ua pa, thiab tawv nqaij.
- Thaum siv phenylethyl phenylacetate, tsis txhob sib cuag nrog daim tawv nqaij thiab nqus tau nws cov vapors.
- Hnav cov hnab looj tes tiv thaiv, tsom iav, thiab cov khoom tiv thaiv ua pa thaum siv.
- Phenylethyl phenylacetate yuav tsum muab cia rau hauv lub thawv airtight, kom deb ntawm ignition thiab oxidants.
- Cov txheej txheem ua haujlwm kom raug yuav tsum tau ua raws li thaum tuav phenylethyl phenylacetate thiab cov lus qhia txog kev nyab xeeb thiab cov cai yuav tsum tau ua.
