    Abstract: The invention relates to a column for the thermal treatment of mixtures containing at least one polymerisable compound. Said column comprises dual flow plates which are provided with openings, the diameter of each opening being constant inside a dual flow plate. The diameter of the openings of said dual flow plates decreases as the distance of the plates from the inlet of the mixture to be treated increases.

    Abstract: The invention relates to a method of producing methyl formiate by reacting excess methanol with carbon monoxide under increased pressure and increased temperature in the presence of an alkalimethylate or alkaline earth methylate as the catalyst in a pressure-proof reactor. The inventive method uses at least two reactor elements, preferably countercurrent reactors, at a temperature of approximately 100 DEG C and a pressure of approximately 100 bar in combination with a solid-matter free desalination of the reactor product. The inventive method provides a means for producing methyl formiate of any quality desired and with an excellent production capacity in a very economical and complication-free manner. The invention further relates to a method of solid-matter free desalination and to devices for carrying out the inventive method.

    Abstract: A description is given of a process for preparing methyl formate by reacting excess methanol with carbon monoxide under superatmospheric pressure and at elevated temperature in the presence of alkali metal methoxide or alkaline earth metal methoxide as catalyst in a pressure-rated reactor, in which the use of at least two reactor elements, preferably operated in countercurrent, at about 100° C. and a pressure of about 100 bar in combination with a solids-free desalting of the reaction product makes possible very economical, largely trouble-free production of methyl formate in any desired quality and with a very good production capacity. Furthermore, the process for solids-free desalting and apparatuses for carrying out this process are described.

    Abstract: In a process for preparing acrylic acid, an acrylic acid-containing product gas mixture obtained by catalytic gas phase partial oxidation of a C 3 precursor of acrylic acid, after direct cooling with a quench liquid, is fractionally condensed in a separating column provided with internals, rising into itself with sidestream takeoff of crude acrylic acid, and the acrylic acid oligomers which form are dissociated and the resulting dissociation gas is subjected to a countercurrent rectification before it is recycled.

    Abstract: A column for the thermal treatment of a mixture has dual-flow stages with openings having a constant diameter within a dual-flow stage. The dual-flow stages at an increasing distance from the addition point of the gases to be treated have openings of decreasing diameter. An Independent claim is also included for the thermal treatment of a mixture comprising at least one polymerizable compound in the column.
