Abstract
THE INVENTION RELATES TO A PROCESS FOR PREPARATION OF AT LEAST ONE OF METHACRYLIC ACID AND A METHACRYLIC ACID ESTER, COMPRISING PROCESS STEPS: A1) GAS PHASE OXIDATION OF AT LEAST ONE C4 COMPOUND TO OBTAIN A REACTION PHASE COMPRISING METHACRYLIC ACID; A2) QUENCHING OF THE REACTION PHASE TO OBTAIN A CRUDE AQUEOUS PHASE COMPRISING METHACRYLIC ACID; A3) EXTRACTION OF AT LEAST A PART OF THE METHACRYLIC ACID FROM THE CRUDE AQUEOUS PHASE COMPRISING METHACRYLIC ACID INTO AN ORGANIC SOLVENT TO OBTAIN A CRUDE ORGANIC PHASE COMPRISING METHACRYLIC ACID AND A FIRST AQUEOUS PHASE, WHEREIN THE FIRST AQUEOUS PHASE COMPRISES COMPONENTS I. AT LEAST 65 WT.%, PREFERABLY IN THE RANGE OF FROM 65 WT.% TO 99.9 WT.%, MORE PREFERABLY IN THE RANGE OF FROM 70 WT.% TO 99.8 WT.% WATER, YET MORE PREFERABLY IN THE RANGE OF FROM 75 WT.% TO 99 WT.%, MORE PREFERABLY IN THE RANGE OF FROM 76 WT.% TO 98.5 WT.%, MORE PREFERABLY IN THE RANGE OF FROM 77 WT.% TO 98 WT.%, EVEN MORE PREFERABLY IN THE RANGE OF FROM 78 WT.% TO 97.5 WT.%, EVEN MORE PREFERABLY IN THE RANGE OF FROM 79 WT.% TO 95 WT.%, YET MORE PREFERABLY IN THE RANGE OF FROM 80 WT.% TO 90 WT.% WATER, BASED ON THE TOTAL WEIGHT OF THE FIRST AQUEOUS PHASE, AND II. NOT MORE THAN 35 WT.%, PREFERABLY IN THE RANGE OF FROM 0.1 WT.% TO 35 WT.%, PREFERABLY IN THE RANGE OF FROM 0.2 WT.% TO 30 WT.%, MORE PREFERABLY IN THE RANGE OF FROM 1 WT.% TO 25 WT.%, YET MORE PREFERABLY IN THE RANGE OF FROM 1. WT.% TO 24 WT.%, MORE PREFERABLY IN THE RANGE OF FROM 2 WT.% TO 23 WT.%, EVEN MORE PREFERABLY IN THE RANGE OF FROM 2.5 WT.% TO 22 WT.%, EVEN MORE PREFERABLY IN THE RANGE OF FROM 5 WT.% TO 21 WT.%, YET MORE PREFERABLY IN THE RANGE OF FROM WT.% TO 20 WT.% OF AT LEAST ONE ORGANIC COMPOUND, BASED ON THE TOTAL WEIGHT OF THE FIRST AQUEOUS PHASE, WHEREIN THE SUM OF THE WEIGHT AMOUNTS OF I. AND II. IS 100 WT.%; A4) SEPARATION AND OPTIONALLY PURIFICATION OF AT LEAST A PART OF THE METHACRYLIC ACID FROM THE CRUDE ORGANIC PHASE COMPRISING METHACRYLIC ACID; 200700658 55 A5)
