Dab tsi yog qhov tsw ntawm Benzyl Acetate

Benzyl Acetate yog qab zib floral fruity tshiab aromatic jasmine ylang haib nyias gardenia muguet lily paj tuberose lily-of-the-valley violet melon watermelon (musk) strawberry apple apricot txiv tsawb butter cherry.

Kev siv ntawm Benzyl Acetate

Benzyl acetate yog cov khoom siv dav siv hauv cov khoom siv niaj hnub vim nws cov ntxhiab tsw qab ntxiag, fruity aroma reminiscent ntawm jasmine los yog cherry blossoms. Nws cov xwm txheej ntau yam ua rau nws muaj kev xaiv nrov rau ntau yam kev siv:

Perfumes thiab Fragrances:Benzyl acetate yog cov khoom tseem ceeb hauv cov tshuaj tsw qab thiab cov tshuaj tsw qab, muab cov ntxhiab tsw ntxhiab tsw ntxhiab tsw ntev. Nws cov aroma qab zib txhim kho tag nrho cov kev paub olfactory, ua rau nws nyiam ntawm cov neeg tsim khoom naj hoom.

Cua Fresheners:Nyob rau hauv cov huab cua fresheners thiab chav tsev tshuaj tsuag, benzyl acetate ua raws li ib tug fragrance enhancer, npog qhov tsis kaj siab tsw thiab tawm hauv qab ib tug tshiab, caw ntxhiab tsw. Nws muaj peev xwm nyob twj ywm hauv huab cua ua rau nws zoo tagnrho rau kev tsim kom muaj cua zoo hauv tsev thiab chaw lag luam.

Cov neeg huv hauv tsev:Benzyl acetate feem ntau muab tso rau hauv cov khoom siv hauv tsev xws li cov tshuaj txau thiab cov tshuaj ntxuav tes kom ntxiv cov tshuaj tsw qab tsw qab. Qhov no yuav pab kom tshem tawm cov ntxhiab tsw phem, ua rau kev tu kom zoo dua qub.

Flavorings:Hauv kev lag luam zaub mov, benzyl acetate yog siv los ua tus neeg sawv cev hauv cov khoom qab zib, dej haus, thiab cov khoom ci. Nws cov txiv hmab txiv ntoo saj pab txhawb qhov kev xav ntawm cov khoom xws li cov khoom qab zib, dej qab zib, thiab pastries, pab txhawb rau lawv qhov profile tag nrho.

Yog Benzyl Acetate yog Organic Compound

Benzyl acetate yog ib qho tshuaj tsw qab ester uas tau nyiam rau nws cov ntxhiab uas zoo ib yam li jasmine, gardenia, thiab lily ntawm hav. Nws yog feem ntau siv los ua cov tshuaj tsw qab hauv paus hauv cov tshuaj tsw qab, tshuaj pleev ib ce, thiab xab npum fragrances, nws kuj yog ib qho ntawm ntau yam hauv kev lag luam tshuaj tsw qab.

Benzyl acetate feem ntau yog tsim los ntawm cov tshuaj synthesis. Ntawm cov tshuaj synthesis txoj kev, esterification cov tshuaj tiv thaiv ntawm acetic acid thiab benzyl cawv (BALC) yog feem ntau siv. Raws li ib tug precursor, BALC yog conventionally tsim thiab ua lag luam npaj los ntawm roj av. Cov txheej txheem no suav nrog benzyl chloride ntawm alkaline hydrolysis. Ntxiv nrog rau cov tshuaj tiv thaiv hnyav, cov khoom noj tsis tuaj yeem txuas ntxiv tau siv rau hauv cov txheej txheem no, yog li ua rau muaj teeb meem sustainability.

Benzyl Acetate Ua li cas

Rau kev tsim khoom lag luam ntawm benzyl acetate, cov txheej txheem yog paub nyob rau hauv uas benzyl chloride tsim los ntawm chlorination ntawm toluene yog hydrolyzed los ntawm alkali, thiab cov benzyl cawv yog esterified nrog acetic acid. Cov txheej txheem no suav nrog ntau theem kev tshwm sim, thiab suav nrog ntau cov kauj ruam ntawm kev sib cais thiab kev ua kom huv tom qab qhov kev cuam tshuam. Yog li ntawd, cov txheej txheem yog complex thiab tsis zoo economically. Ntxiv mus, nyob rau hauv cov tshuaj tiv thaiv hydrolysis ntawm qib thib ob, alkali xws li sodium hydroxide yuav tsum tau nyob rau hauv ib qho nyiaj sib npaug los yog ntau tshaj, thiab ib tug loj npaum li cas ntawm cov ntsev uas muaj cov organic tebchaw yog tsim raws li cov by-product, uas muaj teeb meem tom qab- kho li ntawd.

Nyob rau hauv cov txheej txheem tsis ua lag luam, benzyl acetate yog tsim los ntawm cov tshuaj tiv thaiv ntawm toluene, acetic acid, thiab oxygen nyob rau hauv lub xub ntiag ntawm ib tug catalyst rau oxyacetoxylation. Cov txheej txheem no ua rau benzyl acetate hauv ib kauj ruam cov tshuaj tiv thaiv yam tsis muaj kev tsim cov khoom siv ntsev, kom nws muaj txiaj ntsig zoo rau kev lag luam thiab tuaj yeem ua rau qis ib puag ncig.

Ntawm qhov tod tes, benzyl cawv tuaj yeem tsim los ntawm cov txheej txheem paub hauv qab no. Ntawm cov no, cov txheej txheem (1) thiab (3) yog xyaum ua lag luam:
(1) Hydrolysis ntawm benzyl chloride los ntawm sodium hydroxide.
(2) Hydrolysis ntawm benzyl acetate nyob rau hauv lub xub ntiag ntawm ib tug catalyst.
(3) Kev txo qis ntawm benzaldehyde los ntawm hydrogen nyob rau hauv muaj cov catalyst.

Cov txheej txheem saum toj no (1) thiab (2) ob leeg tsim benzyl cawv los ntawm hydrolysis. Cov txheej txheem (1) siv cov nyiaj sib npaug lossis ntau dua ntawm sodium hydroxide rau stoichiometric cov tshuaj tiv thaiv ntawm benzyl chloride, cuam tshuam nrog cov teeb meem tom qab kev kho mob ntau ntawm cov tshuaj aqueous ntawm cov organic compound-muaj sodium chloride tsim los ntawm cov khoom lag luam. Cov txheej txheem (3) ntiav cov benzaldehyde kim heev raws li cov khoom pib, thiab tsis zoo rau kev lag luam.

Cov txheej txheem (2) ntawm hydrolysis ntawm benzyl acetate los tsim benzyl cawv cov ntaub ntawv muaj txiaj ntsig zoo acetic acid raws li cov khoom lag luam uas tsis tau tso cov dej pov tseg, yog li kev lag luam thiab tsis tshua muaj ib puag ncig.

Txawm li cas los xij, hauv cov txheej txheem no, kev ua haujlwm catalyst tsawg, thiab yuav tsum muaj cov dej ntau heev, kom cov khoom pib concentration qis dua. Yog li, cov txheej txheem no tsis muaj txiaj ntsig zoo hauv kev txiav txim siab ntawm lub zog rau kev tshem tawm cov dej tsis muaj dej los ntawm cov kua tshuaj sib tov.
