Title (EN) SINGLE SOLVENT GAS EXPANDED HYDROFORMYLATION PROCESS
(FR) PROCÉDÉ D'HYDROFORMYLATION À EXPANSION PAR UN SEUL GAZ SOLVANT
Abstract: front page image
(EN)Allyl alcohol, particularly from biobased sources such as glycerol, is hydroformylated to products including 4-hydroxybutyraldehyde and 4-hydroxy-2-methylpropionaldehyde by forming a homogeneous reaction mixture including allyl alcohol, a rhodium-based hydroformylation catalyst and a near critical liquefiable petroleum gas or mixture of such gases, reacting the near critical liquefiable petroleum gas (or gas mixture)-expanded allyl alcohol substrate with carbon monoxide and with hydrogen in the presence of the catalyst, and recovering substantially all of the petroleum gas or gases overhead by reducing the pressure and degassing the product mixture. Dense propane is especially useful as a single inert solvent/diluent, and substantially no other solvent/diluent is needed.
(FR)L'alcool allylique, en particulier provenant de sources biologiques telles que le glycérol, est hydroformylé en des produits comprenant le 4-hydroxybutyraldéhyde et le 4-hydroxy-2-méthylpropionaldéhyde par formation d'un mélange réactionnel homogène comprenant de l'alcool allylique, un catalyseur d'hydroformylation à base de rhodium et un gaz de pétrole liquéfiable presque critique ou un mélange de tels gaz, par réaction du substrat alcool allylique expansé par le gaz de pétrole liquéfiable presque critique (ou le mélange de tels gaz) avec du monoxyde de carbone et avec de l'hydrogène en présence du catalyseur, et par récupération de sensiblement la totalité du ou des gaz de pétrole de tête par réduction de la pression et dégazage du mélange de produits. Le propane dense est particulièrement utile comme seul solvant/diluant inerte, et sensiblement aucun autre solvant/diluant n'est nécessaire.
