CA 2723129

A process for glycerol etherification, comprising a recycle of glycerol and/or mono-ether, to produce glycerol alkyl ethers with low amount of mono-ether by reacting glycerol and olefinic hydrocarbon, and/or the corresponding aldehydes, ketones and alcohols, having 2 to 10 carbon atoms in the presence of homogeneous acid catalyst with hindered formation of olefin oligomers comprising of two essential steps: reaction step (1) neutralization and salt removal step (2).

Procédé d'éthérification de glycérol consistant à recycler glycérol et/ou monoéther afin de produire des éthers de glycérol-alkyl possédant un niveau faible de monoéther par réaction de glycérol et d'hydrocarbure oléfinique, et/ou les aldéhydes, cétones et alcools correspondants, possédant 2 à 10 atomes de carbone en présence d'un catalyseur acide homogène avec formation inhibée d'oligomères d'oléfines comprenant deux étapes essentielles: étape de réaction (1), étape de neutralisation et suppression de sel (2).
