摘要:
L'invention concerne un procédé de conjugaison catalytique des doubles liaisons de corps gras polyinsaturés en vue d'améliorer leurs propriétés siccatives. Le procédé consiste à utiliser comme catalyseur du ruthénium déposé sur charbon à raison de 0,01 à 0,1 % de poids de métal rapporté à celui du produit à conjuguer, à une température comprise entre 180 et 250°C, préférentiellement en présence d'un gaz non oxydant et éventuellement d'un composé protique. Une application est celle des revêtements tels que : peintures et vernis, colles.
摘要:
The invention relates to a method for the metathesis of olefin(s). The method according to the invention comprises bringing at least one fatty acid ester or a fatty acid into contact with a metathesis catalyst, said fatty acid ester or fatty acid comprising at least one unsaturation, wherein the ester or the fatty acid is treated with a sorbent before being brought into contact with the metathesis catalyst, the sorbent being maintained in the reactive medium while the ester or the fatty acid is brought into contact with the metathesis catalyst.
