DOA feem ntau yog synthesized los ntawm adipic acid thiab ethyl hexanol isooctanol hauv qab acid catalysis. Tam sim no, muaj ntau yam catalysts siv los ua kedioctyl supipate, uas tuaj yeem suav tau rau hauv cov kab lus hauv qab no: inorganic acid catalysts, organic acid catalysts, titanate catalysts, khov acid catalysts. Ntawm lawv, khov cov kua qaub catalysts muaj qhov zoo ntawm cov kev ua haujlwm siab, kev xaiv siab, yooj yim kev ua qias tuaj, kev kho kom yooj yim, yooj yim tom qab kho thiab lwm yam. Lawv yog hom ib puag ncig-catalysts nrog dav kev thov kev cia siab, thiab tau nyiam ntau xim. Yog li ntawd, siv cov acid catalyststions es tsis txhob siv lwm hom catalysts los ua sterthesize diacetyl admipate tau dhau los ua kev txhim kho hauv kev lag luam niaj hnub.
Kev ua si yog qhov siab tshwj xeeb cov khoom siv tau tsim nyob rau xyoo 1970. Raws li cov cab kuj catalyst, nws tsis tuaj yeem pab rau kev faib cov nquag, tab sis kuj tseem ua kom muaj peev xwm txo qhov kev ua haujlwm hnyav. Cov tsoos ua kom muaj cov pa roj carbon monoxide yog ib hom spark kho ntxig carbon fiber ntau yog cov pa roj carbon fiber ntau, thiab cov fiber ntau yog them nrog micropores. Nws adsorption muaj peev xwm rau cov roj organic yog ob peb mus rau ntau lub sijhawm siab dua li cov pa roj aav hauv huab cua, thiab cov lej adsorption yog 100 rau 1000 zaug sai dua.
Heteropoly acid yog ntau feem tiv thaiv proton acid nrog lub zog muaj zog. Nws muaj cov kev ua haujlwm siab thiab xaiv tau ntau yam rau kev sib raug zoo, thiab muaj qhov zoo ntawm cov tsis muaj zog, zoo thermal stabilation thiab kev hloov nrawm dua. Nws yog ib qho zoo tshaj plaws catalyst. Nws tau tshaj tawm tias Heteropoly acid thiab nws cov kev txhawb nqa tau siv los ua rau cov tshuaj tiv thaiv adipic acid thiab n octanol mus rau synthesize Doa. Qhov kev pom zoo tshaj plaws yog tias tus qauv hniav phem ntawm cov kua qaub rau cawv yog 1: {}. The amount of catalyst is 1. 5 percent of the mass of adipic acid 4 percent , reaction time 3 5h, the esterification rate can reach 99 1 percent . Nws kuj tseem tau tshaj tawm tias Di-n-ictyl supipate tau synthesized los ntawm adipic acid thiab nog piv txwv zoo nkauj thiab toluene raws li dej nqa tus neeg sawv cev. Qhov zoo tshaj plaws cov txheej txheem muaj raws li hauv qab no: tus nqi hniav ntawm cov pa roj qaub yog 1.8: 1, tus nqi ntawm cov tshuaj tiv thaiv yog 9h, thiab tus esterification muaj 99.23 feem pua.
Lub tswvyim ntawm cov suab paj nruag molecular tau muab tso rau pem hauv ntej xyoo 1932. Nws yog hom ntawm silicoaluminate microporousrystal. Nrog rau kev kawm tob ntawm molecular sieves, lawv tau siv dav dav thiab nyob ib txoj haujlwm tseem ceeb. Piv txwv li, kev ua roj av ua, petrochemical kev lag luam, tshuaj lom neeg tshuaj lom neeg thiab kev lag luam txhua hnub. Noj kom zoo dua ntawm cov ntsiab lus siab muaj peev xwm thiab muaj zog thermal ruaj khov ntawm molecular sieves,Dioctyl supipatetau synthesized los ntawm adipic acid thiab 2 - Etylhexanol nrog hy molecular sieves li catalyst. Qhov kev tawm tsam zoo tshaj plaws yog raws li hauv qab no: Cov tshuaj tiv thaiv kub 160 degree} Cov tshuaj tivthaiv Molf {}, cov tshuaj tiv thaiv loj yog 98.7 feem pua.
