Cov txheej txheem txaj fluidized rau ib-kauj ruam synthesis ntawm methyl acrylate (MA) siv methyl acetate (Ma) thiab formaldehyde (FA) tau tsim thawj zaug. Tshiab spherical antiwear acid-base catalysts Cs-P / -Al2O3 tau npaj siv ultrasonic impregnation txoj kev thiab tus yam ntxwv nrog XRD, BET, SEM, PSD, ICP, TG/DTA, NH3-TPD, thiab CO{{5} }TPD txoj kev. Catalytic kev ua tau zoo raug soj ntsuam, thiab 10.0 wt % Cs–5.0 wt % P / -Al2O3 nrog cov chaw tsis muaj zog acid-base tau txiav txim siab ua qhov zoo tshaj plaws catalyst rau MA ntau lawm. Cov txheej txheem teb saum npoo av (RSM) tau ua haujlwm los txhim kho aldol condensation ntawm Ma nrog FA tshaj 10.0 wt % Cs–5.0 wt % P / -Al2O3. Cov teebmeem ntawm ntau yam txheej txheem xws li qhov kub thiab txias, molar ratio ntawm Ma thiab FA, thiab cov kua hauv ib teev ntawm qhov chaw nrawm (LHSV) ntawm MA yield tau hais los ntawm Box-Behnken sim tsim (BBD). Qhov coefficient ntawm kev txiav txim siab (R2) ntawm tus qauv no yog 0.997, thiab 39.5 mol% tawm los ntawm MA yog tau tom qab optimization. Cov catalyst tsim muaj kev ruaj ntseg siab, tsis muaj qhov txo qis hauv catalytic kev ua haujlwm tom qab 1000 h ntawm kev ntsuas lub neej.

Cov infrared absorption spectra ntawm polymers thiab copolymer ntawm methyl acrylate thiab methyl methacrylate tau raug ntsuas, thiab tom qab ntawd siv los ua lub hauv paus ntawm txoj kev spectrophotometric rau kev tsom xam ntawm cov copolymer. Lub 6.73 μ band, uas tej zaum yuav yog vim methyl (–C-CH3) kev co, raug xaiv los ua cov qhab tseem ceeb rau kev ntsuas cov methyl methacrylate tivthaiv, thaum lub 6.89 μ band tau siv raws li tus qauv. Cov monomer reactivity piv rau copolymerization ntawm methyl acrylate-methyl methacrylate system tau txiav txim siab yog r1=0.5±0.1, thiab r{{10}}.3± 0.4 (M1 methyl acrylate, M2; methyl methacrylate) ntawm 130 degree. Cov txiaj ntsig no tau pom zoo nrog cov yav tas los tau los ntawm txoj kev deuterium tracer. Nws kuj tau pom tias cov txheej txheem siv nyob rau hauv txoj kev tshawb no yog tsim nyog rau kev soj ntsuam ntawm methyl acrylate-methyl methacrylate copolymer.

Acrylic acid, methanol thiab catalyst yuav tsum tau npaj. Acrylic acid yog lub ntsiab reactant, methanol yog tus neeg sawv cev cawv, thiab lub luag haujlwm ntawm cov catalyst yog kom ceev cov tshuaj tiv thaiv.

Kev tsim cov methyl acrylate tsuas yog siv cov tshuaj tiv thaiv esterification. Cov kauj ruam tshwj xeeb yog raws li hauv qab no: ntxiv acrylic acid thiab methanol rau hauv lub reactor raws li ib qho piv txwv, thiab ntxiv cov catalyst tib lub sijhawm. Nyob rau hauv tej qhov kub thiab txias, cov tshuaj tiv thaiv esterification yog nqa tawm. Cov txheej txheem no yuav tsum tau tswj cov tshuaj tiv thaiv tus nqi thiab qhov kub thiab txias kom ntseeg tau tias qhov kev nce qib ntawm cov tshuaj tiv thaiv thiab qhov zoo ntawm cov khoom. Tom qab cov tshuaj tiv thaiv tiav lawm, distillation sib cais yog ua kom tau methyl acrylate crude.

Tom qab kev ua tiav yog ib kauj ruam tseem ceeb hauv kev tsim cov txheej txheem ntawm methyl acrylate, uas feem ntau suav nrog cov hauv qab no: Distillation thiab purification: Distillation thiab purify cov crude methyl acrylate kom tshem tawm impurities thiab noo noo kom tau ib tug high-purity methyl acrylate khoom. Kev kho cov kua khib nyiab: Kho cov kua khib nyiab uas tsim tawm thaum lub sij hawm cov tshuaj tiv thaiv kom tsis txhob muaj kuab paug ib puag ncig. Cov cuab yeej tu: Ntxuav lub reactor thiab cov cuab yeej muaj feem xyuam los xyuas kom meej qhov kev vam meej ntawm cov tshuaj tiv thaiv tom ntej.

Thaum lub sij hawm tsim cov txheej txheem ntawm methyl acrylate, cov teeb meem hauv qab no yuav tsum tau them rau: nruj me ntsis tswj qhov zoo thiab feem ntawm cov ntaub ntawv raw los xyuas kom meej qhov kev vam meej ntawm cov tshuaj tiv thaiv. Tswj cov tshuaj tiv thaiv kub thiab siab kom tsis txhob muaj kev cuam tshuam sab thiab cov khoom puas. Ua haujlwm tu thiab kho dua tshiab ntawm cov cuab yeej los xyuas kom meej tias cov khoom siv thiab cov khoom lag luam zoo. Txhim kho cov kua dej pov tseg thiab kev tswj hwm kev tiv thaiv ib puag ncig kom txo cov pa phem ib puag ncig.
