Production of acrylic acid by partial gas phase oxidation, for use e.g. as monomer, includes extracting acrylic acid with organic solvent from acidic stream obtained in purification column

Manufacture of acrylic acid involves subjecting precursor to heterogeneously catalyzed gas phase partial oxidation with oxygen in catalyst, reducing gas mixture, and subjecting crude acrylic acid to thermal separation process

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

Process for heterogeneously catalyzed partial gas phase oxidation of propylene to acrylic acid

Process for preparing at least one target product by partial oxidation and/or ammoxidation of propylene

Preparation of acrolein or acrylic acid involves conducting starting reaction gas mixture having propylene and molecular oxygen reactants and inert molecular nitrogen and propane diluent gasses through fixed catalyst bed

Process for preparing acrylic acid

Preparation of acrolein or acrylic acid or a mixture thereof by heterogeneously catalyzed partial gas phase oxidation of propylene

Preparing final products by partial oxidation of propylene, useful as intermediate for polymer, comprises subjecting propane to dehydrogenation, separating and subjecting the gas mixture in heterogeneous catalyzed gasphase-partial oxidation
