Abstract

A PROCESS FOR PREPARING ACRYLIC ACID AND/OR AN ACRYLATE COMPRISING THE FOLLOWING STAGE A AND, IF DESIRED, B AND, IF DESIRED, C: A: COOLING A GASEOUS REACTION MIXTURE WHICH COMPRISES ACRYLIC ACID AND IS OBTAINED IN THE GAS-PHASE OXIDATION TO PREPARE ACRYLIC ACID, USING AN ACRYLIC ACID CONTAINING NOT MORE THAN 5% BY WEIGHT OF WATER, TO GIVE A GASEOUS MIXTURE COMPRISING (METH)ACRYLIC ACID; B: SEPARATING THE GASEOUS MIXTURE COMPRISING ACRYLIC ACID TO GIVE A LOW-BOILING FRACTION AND A BOTTOM PRODUCT WHICH COMPRISES CRUDE ACRYLIC ACID, AND C: ESTERIFYING THE CRUDE ACRYLIC ACID OBTAINED IN STAGE B BY MEANS OF ONE OR MORE ALKANOLS, TO GIVE AN ESTERIFICATION MIXTURE COMPRISING ONE OR MORE ACRYLATES, ONE OR MORE ACETIC ESTERS, ONE OR MORE MALEIC ESTERS, AND OLIGOMERIC AND POLYMERIC ACRYLATES.
