Abstract: A process for transporting a liquid monomer phase which has been withdrawn from a storage vessel and comprises methacrylic monomers to an extent of ≧90% by weight, in a tank truck or in a tanker ship, in which the liquid monomer phase is subjected to a separating operation on the route from the storage vessel into the tank of a tank truck or of a tanker ship in order to separate polymer of the monomer present in dissolved form in the liquid monomer phase.

Abstract: Monomer composition comprises (a) liquid N-vinyl-epsilon -caprolactam and (b) at least a N-oxyl-compound of secondary amine, which carries no hydrogen atoms at the alpha -carbon atom. An independent claim is included for use of the monomer composition for polymerization reactions, where the monomer composition is fluidly stored at above 40[deg] C and fed to the polymerization reactor when required.

Abstract: Separating a three carbon precursor compound of the acrylic acid as main component containing acrylic acid and glyoxal as byproduct in a product mixture of a heterogeneously catalyzed partial gas phase oxidation, comprises producing a liquid phase containing at least 70 wt.% of acrylic acid and at least 200 mol.ppm of glyoxal, crystallatively separating the glyoxal from the acrylic acid and concentrating the acrylic acid in the formed crystallisate and the glyoxal in the remaining mother liquor during the crystallization.

Abstract: A process for preparing oligomers by continuous oligomerization of butenes is described, wherein a) a feed stream (1) comprising I-butene and 2-butene in a total concentration of from 10 to 70% by weight and from 10 to 60% by weight of isobutane is reacted until more than 60% by weight of the I-butene comprised in the feed stream (1 ) but less than 50% by weight of the 2-butene comprised in feed stream (1) have been converted into oligomers. b) The oligomers obtained in a) are separated off and optionally passed to a further work-up and the remaining residual stream is fed to work-up by distillation. c) Isobutane is separated off by distillation from the residual stream, and d) the isobutane-depleted stream obtained after the work-up by distillation c) is reacted to form oligomers.

Abstract: A process for storing a monomer phase which is liquid under the conditions of storage and comprises methacrylic monomers to an extent of ≧95% by weight and has been obtained by condensation out of a gaseous phase or by melting a crystalline phase, in a storage vessel, in which polymer of the monomer present in dissolved form in the liquid monomer phase is removed therefrom on the route from its generation into the storage vessel, and also a process for withdrawing liquid monomer phase from the storage vessel in which polymer of the monomer present in dissolved form in the monomer phase is likewise removed.

Abstract: Inhibiting the unwanted radical polymerization of acrylic acid present in a liquid phase (P1), comprises adding at least one chemical compound of copper to the liquid phase (P1). The amount of acrylic acid is 10 wt.%. The liquid phase additionally contains propionic acid (at least 100 wt. parts per million, based on wt. of acrylic acid in the liquid phase) and glyoxal (at least 100 wt. parts per million, based on wt. of acrylic acid in the liquid phase). An independent claim is also included for the liquid phase (P1), comprising at least one chemical compound of copper.

Abstract: Ein Verfahren der Abtrennung einer rohen Acrylsäure aus einem Glyoxal als Nebenprodukt enthaltenden Produktgasgemisch einer heterogen katalysierten partiellen Gasphasenoxidation wenigstens einer C-Vorläuferverbindung, das die Absorption der Acrylsäure in einem hochsiedenden Absorptionsmittel sowie die rektifikative Aufarbeitung des resultierenden Absorbats umfasst, und bei dem von aus dem Sumpfraum der Absorptionskolonne entnommener Sumpfflüssigkeit in einer Destillationseinheit darin enthaltenes Absorptionsmittel abdestilliert und in die Absorption rückgeführt wird, bevor dabei verbliebene Schwersieder ausgeschleust werden, und bei dem durch Beschränkung der Schwersiederverweilzeit in der Destillationseinheit der Glyoxalgehalt der rohen Acrylsäure vermindert wird.
