Abstract: (METH)ACRYLIC MONOMERS ARE SEPARATED BY A THERMAL SEPARATION PROCESS BY ASCENDING AT LEAST ONE ASCENDING GASEOUS STREAM IN A SEPARATING COLUMN CONTAINING A SEQUENCE OF MASS TRANSFER TRAYS AND A LIQUID STREAM THAT CONTAINS DISSOLVED POLYMERIZATION INHIBITOR WHICH DESCENDS IN THE SEPARATING COLUMN, AND IN AT LEAST ONE OF THE STREAMS BEING (METH)ACRYLIC MONOMERS; AND SPRAYING THE INNER SURFACE OF THE SEPARATING COLUMN WITH THE DESCENDING LIQUID STREAM THAT CONTAINS THE DISSOLVED POLYMERIZATION INHIBITOR, AND THE SEPARATING COLUMN HAVING INTERNALS, CERTAIN AREAS OF WHICH ARE SHADOW REGIONS OF THE SPRAYED DESCENDING LIQUID STREAM; AND WHICH SHADOW REGIONS ARE EQUIPPED BY COVERING MEANS (2) WHICH PREVENT CONTACT OF THE SHADOW REGIONS WITH (METH)ACRYLIC MONOMERS AND CONSEQUENTLY UNDESIRED POLYMERIZATION OF MONOMER.

Abstract: The invention relates to a method for filling a vertical tube having an inne r diameter of 50 mm or less with catalyst particles. According to said method, a filling aid comprising a flexible longitudinal body is introduced into the vertical tube, the ratio of the cross-section of the flexible longitudinal body to the cross-section of the tube being between 0.003 and 0.08, and the tube is filled with the catalyst particles.

Abstract: A process measures the pressure of a gas phase containing (meth)acrylic acid, the esters and/or nitrites thereof of a rectification and/or absorption column via open drillholes in the column wall and lines from the drillholes to the transducers by purging the lines with an oxygen-containing gas in the direction toward the open drillhole.
