Title (EN) PROCESS FOR PREPARING AN UNSATURATED CARBOXYLIC ACID SALT
(FR) PROCÉDÉ DE PRÉPARATION D'UN SEL D'ACIDE CARBOXYLIQUE INSATURÉ
Abstract: front page image
(EN)A catalytic process for preparing an α,β-ethylenically unsaturated carboxylic acid salt from an alkene, carbon dioxide and an alkoxide having a secondary or tertiary carbon atom directly bound to a [O-] group is described. The alcohol byproduct is distilled off after an intermediate phase separation. This provides pure α,β-ethylenically unsaturated carboxylic acid salt at minimum effort.
(FR)Procédé catalytique de préparation d'un sel d'acide carboxylique α,β éthyléniquement insaturé, à partir d'un alcène, de dioxyde de carbone et d'un alcoxyde ayant un atome de carbone secondaire ou tertiaire lié directement à un groupe [O-]. Le sous-produit d'alcool est éliminé par distillation après une séparation de phase intermédiaire. Ceci permet d'obtenir un un sel d'acide carboxylique α,β éthyléniquement insaturé avec un minimum d'effort.
