Acrolein dimethyl acetal yog ib hom acetal. Acrolein, raws li cov tshuaj tiv thaiv nruab nrab, tau siv ntau ntxiv hauv kev sib xyaw ntawm cov tshuaj, tshuaj tua kab, txuj lom, resins thiab lwm yam. Kev npaj dav dav dimethyl acetal acrolein, acrolein diethyl acetal' txoj hauv kev yog rau acrolein nrog methanol lossis ethanol lub cev qhuav dej ua kom cov tshuaj tiv thaiv nyob rau hauv cov kua qaub catalyst, tab sis vim yog qhov acrolein thiab muaj sia nyob, tsis ruaj khov hauv cov kua nruab nrab, thiab vim tus qauv ntawm qhov chaw siv tshuaj tua kab mob tsis pom tseeb, thiab cov tshuaj tiv thaiv ntawm methanol, ethanol ua rau muaj kev xaiv acetal tsawg, muaj kev phiv, ua kom yooj yim, tsis yooj yim rau kev tsim khoom loj. CN201110201192.9 tau tshaj tawm tias acrolein tau tawm tsam nrog trimethyl orthoformate lossis triethyl orthoformate nyob rau hauv qhov xwm txheej ntawm cov kua qaub catalyst. Vim yog qhov ua kom tsis muaj zog ntawm orthoformate hauv cov tshuaj tiv thaiv tau ntau dua li ntawm methanol thiab ethanol, qhov sib xyaw acetal tau tsim los ntawm cov tshuaj tiv thaiv, uas muaj kev xaiv siab, tsis tshua muaj kev cuam tshuam thiab kev ua kom yooj yim, thiab tsim nyog rau kev tsim khoom loj. Cov txheej txheem Tshuaj Tshuaj yog raws li hauv qab no: 500ml peb lub qhov ncauj nrog cov nplawm nplawm, tso lub raj dej thiab tus pas ntsuas kub tso rau hauv chav da dej, ntxiv 280g orthoformate trimethyl ester (2.64mol), pib nplawm, maj mam ntxiv 1.8g sulfonic acid (0.019mol) ), qhov ntsuas kub ntawm cov cuab yeej da dej yog tswj los ntawm 30 40 ℃, tas li tso dej acrolein 140g (2.54mol), Tsis pub dhau 1 teev, txuas ntxiv mus rau 2 teev, thiab tom qab ntawd ntxiv sodium carbonate, nruab nrab rau PH7 7.5, nplawm rau 2 teev, sawv ntsug 4 teev, lim, tshem tawm cov khib nyiab uas tsis haum, cov dej ua kom cua txias, cuam tshuam 89 91 ° C distillate 201g (GC kuaj pom, 98.8%), uas yog, acrolein dimethyl acetal, tawm los 81.8%.
