Abstract
Fremgangsmåte ved katalytisk oxydasjon av olefiner.
Description
Oxydasjon av olefiner med forskjellige flerkomponentkata-lysatorer er kjent. I US patentskrift nr. 3642930.er det beskrevet at visse komplekse katalysatorer kan anvendes for oxydasjon av olefiner til umettede aldehyder og syrer. Disse katalysatorer er riktignok sterkt ønskede for denne oxydasjon, men en kontinuerlig forskning er blitt utført for å finne frem til andre katalysatorer som vil kunne forbedre resultatene erholdt med katalysatorene beskrevet i det nevnte US patentskrift. Den foreliggende fremgangsmåte er et resultat av en slik forskning.
Oppfinnelsen angår således en fremgangsmåte ved fremstilling av umettede aldehyder og syrer fra propylen eller isobutylen ved oxydasjon i dampfase av propylen eller isobutylen med molekylært oxygen ved en temperatur på 200-600°C i nærvær av. en katalysator, og fremgangsmåten er særpreget ved at det som katalysator anvendes en katalysator med formeleno
hvori X betegner Ce, Th, Mn, Pr, Nb, Ge, Cr,
Y, Zr, Ru, Ga, Sn, In, Cu, La, Ta,
W, Sb eller en blanding derav,
A betegner et alkalimetall, Tl eller en blanding derav,
D betegner Ni, Co, Mg, Zn, Cd, Ca, Sr, eller en blanding derav,
E betegner P, As, B, S, Al eller en blanding derav, og
a betegner et tall som er større enn 0 men mindre enn 5,
b og d er 0-4, c, f og g er 0,1-12, og
x betegner det antall oxygenatomer som er nødvendig for å tilfredsstille valensbehovet for de andre tilstedeværende elementer.
Den foreliggende oxydasjonsprosess fører til spesielt
ønskede resultater ved atmosfæretrykk eller overatmosfærisk trykk.
Det sentrale trekk ved den foreliggende fremgangsmåte er den spesielt anvendte katalysator. Katalysatorene kan være en hvilken som helst av de katalysatorer som er definert ved hjelp av den ovenfor angitte formel. Ved den foretrukne utførelses-form av den foreliggende fremgangsmåte innarbeides hvert av ele-mentene betegnet ved hjelp av X adskilt i katalysatoren. Dette kan enkelt oppnås ved uavhengig å la X betegne de forskjellige elementer. For utførelse av den foreliggende fremgangsmåten er dessuten de katalysatorer foretrukne som inneholder kalium, rubidium, cesium eller en blanding derav, og de katalysatorer som inneholder nikkel, kobolt eller en blanding derav.
De for utførelse av den foreliggende fremgangsmåte anvendte katalysatorer kan fremstilles ved hjelp av innen den an-gjeldende teknikk generelt kjente metoder. Disse metoder omfatter
koutfelling av oppløselige salter. Fremstillingen av katalysatorene er mer detaljert beskrevet nedenfor.
Katalysatorene for utførelse av den foreliggende fremgangsmåte kan anvendes som bårne eller ubårne katalysatorer. Av egnede bærermaterialer kan nevnes siliciumdioxyd, aluminiumoxyd, alundum, titandioxyd, zirconiumdioxyd, siiciumcarbid og lignende forbindelser.Katalysatorene kan også anvendes i forskjellig fysikalsk form. De kan anvendes i en reaktor med statisk skikt eller i en hvirvelskiktreaktor.
Fremgangsmåten for.oxydasjon av propylen eller isobutylen er velkjent innen teknikken. Generelt bringes en blanding av olefinet og molekylært oxygen, eventuelt i nærvær av vanndamp eller et annet fortynningsmiddel, i kontakt med.en katalysator ved en forhøyet temperatur på 200-600°C i en tilstrekkelig kontakttid til at olefinet vil omdannes til det tilsvarende umettede aldehyd eller syre. Produktet fra disse reaksjoner inneholder normalt en meget stor andel av aldehydet og en mindre biproduktmengde av den umettede syre. Kontakttiden kan variere sterkt fra et par sekunder til flere sekunder eller derover. Reaksjonen kan utføres ved atmosfæretrykk, overatmosfærisk trykk eller underatmosfærisk trykk, idet anvendelse av overatmosfærisk trykk er vanlig anvendt i teknisk målestokk.
En spesiell fordel ved de for utførelse av den foreliggende fremgangsmåte anvendte katalysatorer er at de er istand til å motstå tilførsel av store olef. inmengder over katalysatoren i en viss tid. Denne tilførselsmengde måles vanligvis som WH som står for olefinvekten pr., katalysatorvekt pr. time. Disse katalysatorer kan med andre ord effektivt anvendes for store olefinmengder. Kjente katalysatorer er tilbøyelige til å være mindre effektive når store olefinmengder tilføres i en viss tid.
