Tuam Tshoj Tus Nqi Zoo Triphenylmethane peb isocyanate (ethyl acetate tov) CAS: 141-78-6 Hom: Desmodur_RE

1.Ethyl acetate yog siv los ua cov kua roj vanish, lacquers, thiab nitrocellulose;raws li anartificial txiv hmab txiv ntoo tsw;hauv kev tu cov ntaub ntawv; thiab hauv kev tsim cov khoom siv dag thiab tawv, tshuaj tsw qab, thiab cov duab thaij duab thiab daim hlau (Merck 1996).Ethyl Acetate feem ntau yog siv los ua cov kuab tshuaj hauv cov tshuaj tiv thaiv organic.Environmental contaminants;Khoom noj khoom haus paug.

2.Ethyl acetate feem ntau yog siv los ua cov kuab tshuaj thiab diluent, tau txais kev nyiam vim nws cov nqi qis, tsis muaj tshuaj lom, thiab cov ntxhiab tsw zoo.Piv txwv li, nws yog feem ntau siv los ntxuav cov laug cam thiab hauv qee cov kua roj vanish tshem tawm (acetone thiab acetonitrile kuj siv).Cov taum kas fes thiab tshuaj yej nplooj yog decaffeinated nrog cov kuab tshuaj no.Nws kuj yog siv rau hauv cov xim raws li ib tug activator los yog hardener.Hauv cov tshuaj tsw qab, nws evaporates sai sai, tsuas yog cov ntxhiab tsw ntawm cov tshuaj tsw qab ntawm daim tawv nqaij.
3 - 1 - Kev siv chav kuaj
Hauv chav kuaj, cov khoom sib xyaw uas muaj ethyl acetate feem ntau yog siv hauv kem chromatography thiab extractions.Ethyl acetate tsis tshua raug xaiv los ua cov tshuaj tiv thaiv hnyav vim tias nws nquag ua rau hydrolysis thiab trans esterification.
3 - 2 - tshwm sim hauv cawv
Ethyl acetate yog cov ester ntau tshaj plaws hauv cawv, yog cov khoom lag luam ntawm cov organic acids uas tsis muaj zog tshaj plaws - acetic acid, thiab ethyl cawv generated thaum lub sij hawm fermentation.Lub aroma ntawm ethyl acetate yog qhov tseeb tshaj plaws nyob rau hauv cov hluas wines thiab pab txhawb rau kev nkag siab ntawm "fruitiness" hauv cawv.
3 - 3 - Entomological tua neeg sawv cev
Nyob rau hauv lub tshav pob ntawm entomology, ethyl acetate yog ib tug zoo asphyxiant siv nyob rau hauv kev sau kab thiab kawm.Nyob rau hauv ib lub thawv tua raug them nrog ethyl acetate, cov vapors yuav tua cov kab uas sau tau (feem ntau yog cov neeg laus) sai sai yam tsis muaj kev puas tsuaj.Vim tias nws tsis yog hygroscopic, ethyl acetate kuj ua kom cov kab mos txaus kom tso cai rau kev sib txuas kom haum rau kev sau.

3. Pharmaceutic pab (flavor);Artificial txiv hmab txiv ntoo essences;hnyav rau nitrocellulose, kua roj vanish, lacquers, thiab dav hlau dopes;kev tsim cov hmoov tsis muaj pa taws, cov tawv nqaij, cov duab thaij duab thiab cov phaj, cov khoom siv dag, cov tshuaj tsw qab;ntxuav textiles, thiab lwm yam.
