Method for producing acrolein and/or acrylic acid

Preparation of partial oxidation or ammoxidation product of propylene, e.g. acrolein, involves subjecting dehydrogenated crude propane in the presence of unconverted propane to heterogeneously catalyzed gas phase partial reaction

Verfahren zur herstellung von acrolein, oder acrylsäure oder deren gemisch aus propan

Process for continuous heterogeneously catalyzed partial dehydrogenation of at least one hydrocarbon to be dehydrogenated

Preparation of at least one partial oxidation and/or ammoxidation product of propylene

Continuous recovery of (meth)acrylic acid from oxidation reaction gas comprises absorbing in high boiling solvent and rectifying obtained solution at high temperature to reduce product loss as di(meth)acrylic acid

Preparation of acrylic acid by heterogeneously catalyzed partial gas phase oxidation of propylene

Production of acrolein and acrylic acid, e.g. chemical intermediate and monomer, comprises dehydrogenation and partial oxidation of propane by adding cycle gas at point where propane in main feed is partly dehydrogenated

Preparation of (meth)acrolein and/or (meth)acrylic acid by heterogeneously catalyzed partial oxidation of C3 and/or C4 precursor compounds in a reactor having thermoplate modules

Partial oxidation in gas phase of three and/or four carbon precursor compounds to (meth)acrolein and/or (meth)acrylic acid with particulate catalyst in reactor having cuboidal thermoplate modules, cylindrical shell, and sealing element(s)
