Zaub mov txuj lom:
Benzyl cawv yog ib qho ntawm cov khoom noj qab haus huv uas tau tso cai siv rau hauv Cov Qauv Kev Noj Qab Haus Huv rau Kev Siv Cov Khoom Noj Ntxiv hauv Suav teb, uas yog ntxiv rau cov txiv hmab txiv ntoo xws li almonds, qab zib txiv kab ntxwv, txiv hmab txiv ntoo, txiv hmab txiv ntoo, strawberries, thiab lwm yam. Piv txwv li, hauv kev tsim cov khoom qab zib, dej qab zib, thiab lwm yam khoom noj, nws tuaj yeem siv los ua cov khoom xyaw flavoring kom muab cov khoom muaj aroma.
txoj kev no yog txoj kev lag luam tseem ceeb hauv tsev thiab txawv teb chaws. Benzyl cawv yog tau los ntawm azeotropic hydrolysis ntawm benzyl chloride thiab alkali aqueous tov, thiab benzyl ether yog tsim nyob rau tib lub sij hawm, mus txog 10%. Kev kub siab, kub siab thiab nce alkali concentration yog txhua yam zoo rau kev tsim los ntawm - khoom. Txoj kev no muab faib ua batch method thiab nruam txoj kev.
Batch txoj kev: dej, dej qab zib tshauv thiab benzyl chloride yog ntxiv rau cov hlau reactor nruab nrog ib tug reflux condenser thiab lub tsho, nplawm thiab rhuab, refluxed kom txog thaum tsis muaj carbon dioxide khiav, txias lub reactant, ntxiv ntsev rau lub saturated txheej, thiab ua tib zoo cais lub sab sauv txheej kom tau crude cawv. Cov cawv cawv tuaj yeem tau los ntawm lub tshuab nqus tsev distillation kom tau txais qib benzyl cawv nrog cov txiaj ntsig ntawm 70% ~ 72%. Cov residual benzyl chloride hauv hydrolysis tuaj yeem kho nrog tertiary amines xws li Urotropine (hexamethylenetetramine), Nws tuaj yeem zam qhov tsim ntawm benzyl ether hauv cov txheej txheem tom qab distillation. Ntxiv cov kuab tshuaj inert xws li chlorobenzene hauv hydrolysis tuaj yeem cuam tshuam qhov tsim ntawm benzyl ether thiab tau txais cov khoom ntshiab.
Nruam txoj kev: cov kua aqueous ntawm benzyl chloride thiab alkali yog tag nrho sib xyaw ntawm qhov kub siab (180-}275 degree) thiab siab siab (1-6.8mpa) thiab tom qab ntawd nkag mus rau hauv thaj chaw hydrolysis. Lub sijhawm hydrolysis tsuas yog ob peb feeb xwb. Qhov kom zoo dua ntawm cov txheej txheem txuas ntxiv yog tias muaj ob peb cov khoom lag luam thiab nws tuaj yeem nqa tawm hauv ntauwd reactor, raws li qhia hauv daim duab . 3. Raws li cov xwm txheej tsim nyog, cov txiaj ntsig ntawm benzyl cawv nrog purity ntawm 99.8% yog 98%, thiab cov tshuaj tiv thaiv tas mus li kuj tuaj yeem nqa tawm hauv cov reactor nrog nplawm.
Thaum tsis muaj catalyst, toluene yog oxidized nyob rau hauv cov kua theem (170-220 degree, 1-1.5mpa) rau hydrogenated benzyl peroxide. Tom qab cov hydrogenated benzyl peroxide sib cais, nws tuaj yeem kho nrog cov kua dej ntawm sodium sulfite tsawg dua lossis sib npaug li 20℃kom tau benzyl cawv nrog cov txiaj ntsig ntawm 92.6%, lossis nws tuaj yeem hydrogenated nyob rau hauv lub xub ntiag ntawm catalyst (xws li palladium thiab pob txha pob txha npib tsib xee) kom tau benzyl cawv.
Cov tshuaj tiv thaiv heterogeneous catalytic muaj txiaj ntsig zoo rau kev sib cais ntawm cov khoom siv tshuaj tiv thaiv. Nyob rau hauv lub xub ntiag ntawm CO thiab H2O, txhawb rhodium pawg tuaj yeem txo benzaldehyde hauv 96% tawm los.
(1) Benzoic acid txo txoj kev benzoic acid tsis tuaj yeem txo ncaj qha los ntawm NaBH4, tab sis tuaj yeem txo qis ncaj qha lossis los ntawm kev ntxiv lwm cov reagents, xws li AlCl3 lossis I2. Txawm li cas los xij, thaum Zn (BH4) 2 yog refluxed hauv THF hnyav, benzoic acid tuaj yeem txo qis rau benzyl cawv nrog cov txiaj ntsig ntawm 90%.
(2) Kev txo qis ntawm NaBH4 los ntawm qhov sib thooj ester tsis tuaj yeem siv los txo cov ester, yog li NaBH4 feem ntau pauv nrog cations kom nws txo cov ester. LiBH4 tau tshaj tawm ua ntej hauv cov ntaub ntawv. Nws tuaj yeem raug txo los ntawm reflux nyob rau hauv lub xub ntiag ntawm THF thiab ether. Kev npaj yuav tsum tau kim lithium chloride, uas txwv tsis pub siv lithium tetrahydroborate. Zn (BH4) 2 kuj tau tsim nyob rau xyoo tas los no thiab tuaj yeem siv rau kev txo qis ntawm esters. Methyl benzoate tau refluxed nrog Zn (BH4) 2 thiab cyclohexene nyob rau hauv nitrogen tiv thaiv rau 4H nrog ib tug yield ntawm 75%.
siv - Cov synthesis ntawm benzyl cawv los ntawm benzene thiab formaldehyde yog catalyzed los ntawm cyclodextrin. High purity benzyl cawv tuaj yeem npaj los ntawm toluene, cua thiab hydrogen los ntawm kev kub siab oxidation -txo txoj kev.
