Title
(EN) PRODUCTION OF ALKYL ESTERS OF ACRYLIC ACID
(FR) PRODUCTION D'ESTERS ALKYLIQUES D'ACIDE ACRYLIQUE
Abstract
(EN)
A process for producing a mixture including acrylic acid or derivatives thereof, the process including the step of contacting a mixture of lactic acid or derivatives thereof and a solvent over a dehydration catalyst to produce the mixture including alkyl esters of acrylic acid, wherein the density of the solvent ranges from about 10 to about 500 kg/m3 under operating conditions.
(FR)
L'invention concerne un procédé de production d'un mélange comprenant de l'acide acrylique ou des dérivés de celui-ci, le procédé comprenant une étape consistant à mettre en contact un mélange d'acide lactique ou de dérivés de celui-ci et un solvant sur un catalyseur de déshydratation pour produire un mélange comprenant des esters alkyliques d'acide acrylique, la densité du solvant étant comprise entre environ 10 et environ 500 kg/m3 dans des conditions de fonctionnement.
