Claims (12)
1. Fremgangsmåde til oprensning af en væsketilførsel, der omfatter mindre end 0,009 vægt-% vand og omfatter monochloreddikesyre, dichloreddikesyre, eventuelt syrechlorider, eventuelt anhydrider og eventuelt eddikesyre, hvilken fremgangsmåde omfatter trinnene: (a) at tilsætte vand til væsketilførslen, således at der opnås en væsketilførsel, der omfatter på mellem 0,01 og 5 vægt-% vand, baseret på den totale vægt af væsketilførselen, og (b) efterfølgende at udsætte væsketilførslen, der er opnået i trin (a), for et katalytisk hydrodechloreringstrin ved at bringe den i kontakt med en hydrogenkilde for at omdanne dichloreddikesyren til monochloreddikesyre i nærvær af en fast heterogen katalysator til hydrogenering, der omfatter et eller flere metaller fra gruppe VIII i det periodiske system over grundstofferne, som er deponeret på en bærer.
2. Fremgangsmåden ifølge krav 1, hvor, forud fortrin (a), væsketilførslen strippes ved at anvende HCI ved et tryk på mellem 2 og 10 bar.
3. Fremgangsmåde ifølge krav 1 eller 2, hvor den heterogene katalysator omfatter på mellem 0,1 og 3 vægt-%, fortrinsvis mellem 0,5 og 2 vægt-%, baseret på den totale vægt af den heterogene katalysator, af det ene eller de nævnte flere metaller fra gruppe VIII i det periodiske system over grundstofferne.
4. Fremgangsmåde ifølge ethvert af de foregående krav, hvor den heterogene katalysator omfatter palladium og/eller platin.
5. Fremgangsmåde ifølge ethvert af de foregående krav, hvor bæreren er valgt fra gruppen bestående af aktivt kul, siliciumdioxid, aluminiumoxid, zirconiumoxid og titanoxid, og eventuelt omfatter svovl eller en eller flere svovlholdige komponenter.
