  • Publication number: 20150344394
    Abstract: A process for preparing acrylic acid, comprising (i) providing a stream S4 comprising a formaldehyde source and acetic acid; (ii) contacting stream S4 with an aldol condensation catalyst comprising a zeolitic material comprising aluminum in the framework structure to obtain a stream S6 comprising acrylic acid, the framework structure of the zeolitic material in (ii) comprising YO2 and Al2O3, and Y being a tetravalent element; where the total content of alkali metal and alkaline earth metal in the zeolitic material in (ii), calculated as alkali metal oxide and alkaline earth metal oxide, is from 0% to 0.1% by weight, based in each case on the total weight of the zeolitic material, and where the aldol condensation catalyst in (ii) comprises, outside the framework structure of the zeolitic material present therein, from 0% to 1% by weight of vanadium, based on vanadium as vanadium(V) oxide.

  • Patent number: 9115070
    Abstract: A process for preparing acrylic acid from ethylene oxide and carbon monoxide, in which ethylene oxide is carbonylated in an aprotic solvent with carbon monoxide in the presence of a cobalt catalyst system to give poly-3-hydroxypropionate, the cobalt content in the poly-3-hydroxypropionate formed is reduced with the aid of water and/or an aqueous solution as a precipitation and/or wash liquid, and the poly-3-hydroxypropionate is subsequently split by thermolysis to give acrylic acid.

  • Publication number: 20140343319
    Abstract: In a process for preparing acrylic acid, a reaction gas which comprises a gaseous formaldehyde source and gaseous acetic acid and in which the partial pressure of the formaldehyde source, calculated as formaldehyde equivalents, is at least 85 mbar and in which the molar ratio of the acetic acid to the formaldehyde source, calculated as formaldehyde equivalents, is at least 1 is contacted with a solid condensation catalyst. The space-time yield can be enhanced significantly by increasing the partial pressure of the reactants. The space-time yield remains high even after prolonged process duration.

  • Publication number: 20140343318
    Abstract: Process for preparing a vinylidenecarboxylic acid or ester thereof, wherein a reaction gas comprising gaseous formaldehyde, molecular oxygen and an alkycarboxylic acid or ester thereof is brought into contact with a solid catalyst whose active composition comprises a vanadium-phosphorus oxide having an average oxidation state of vanadium of from +4.40 to +5.0 to give a product gas comprising the vinylidenecarboxylic acid or ester thereof.
