A continuous transesterification method for preparing polyol polyesters is disclosed. The transesterification reaction of alkyl fatty acid esters and polyols to make polyol polyesters can be coupled with a process to make a lower alkyl, esters of fatty acids. An inert gas is used to remove the alcohols. The gaseous alcohols derived from the transesterification reaction are used as the source of alcohol in the lower alkyl esters synthesis and the inert gas from the alcohol stream can be recycled. The process comprises preparing fatty acid methyl esters, recovering the methyl esters and then transesterifying a polyol in a solvent-free two stage process with the fatty acid methyl esters.
La présente invention concerne un procédé continu de transestérification destiné à la préparation de polyesters de polyols. La réaction de transestérification d'esters d'acides gras d'alkyle et de polyols donnant des polyesters de polyols, peut être couplée à un procédé de fabrication d'un alkyle inférieur, d'esters d'acides gras. Un gaz inerte est utilisé pour enlever les alcools. Les alcools gazeux provenant de la réaction de transestérification sont utilisés comme source d'alcool dans la synthèse des esters d'alkyles inférieurs, et le gaz inerte provenant du courant d'alcool peut être recyclé. Le procédé consiste à préparer des esters méthyliques d'acides gras, à récupérer les esters méthyliques, puis à transestérifier un polyol dans un processus en deux temps sans solvant, avec les esters méthyliques d'acides gras.
