Taw qhia
Isoamyl acetate hmoov. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm isoamyl acetate:
Zoo:
1. Cov tsos: cov kua tsis muaj xim.
2. Kev hnov tsw: muaj ib tug zoo li txiv hmab txiv ntoo aroma.
3. Ceev: txog 0.87 g / cm3.
5. Solubility: soluble nyob rau hauv ntau yam organic solvents, xws li cawv thiab ethers.
Siv:
1. Nws yog siv los ua cov kuab tshuaj hauv kev lag luam, uas tuaj yeem siv los yaj cov resins, coatings, dyes thiab lwm yam khoom.
2. Nws kuj tseem siv tau los ua cov khoom siv tshuaj tsw qab, feem ntau pom muaj nyob hauv cov txiv hmab txiv ntoo tsw qab.
3. Nyob rau hauv cov organic synthesis, nws yuav siv tau raws li ib tug ntawm cov reagents rau esterification cov tshuaj tiv thaiv.
Txoj kev:
Txoj kev npaj ntawm isoamyl acetate feem ntau yog raws li hauv qab no:
1. Esterification cov tshuaj tiv thaiv: isoamyl cawv yog reacted nrog acetic acid nyob rau hauv acidic tej yam kev mob los tsim isoamyl acetate thiab dej.
2. Etherification cov tshuaj tiv thaiv: isoamyl cawv yog reacted nrog acetic acid nyob rau hauv alkaline tej yam kev mob los tsim isoamyl acetate thiab dej.
Cov ntaub ntawv kev nyab xeeb:
1. Isoamyl acetate yog cov kua hluav taws xob hluav taws xob thiab yuav tsum tau ceev kom deb ntawm cov nplaim taws qhib thiab kub siab.
2. Hnav cov hnab looj tes thiab looj tsom iav kom tsim nyog thaum siv kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
3. Tsis txhob nqus cov vapor ntawm cov khoom thiab xyuas kom meej tias qhov chaw ua haujlwm yog qhov cua zoo.
4. Yog tias koj nqos, nqus pa los yog nkag mus rau hauv cov tshuaj ntau, nrhiav kev kho mob tam sim ntawd.
