Title
(EN) PROCESS FOR PREPARING POLYGLYCEROL AND MIXED ETHERS
(FR) MÉTHODE DE PRÉPARATION DE POLYGLYCÉROL ET D'ÉTHERS MIXTES
Abstract
(EN)
Disclosed is a method of reacting glycerol to form polyglycerol or mixed ethers of glycerol or other alcohols (e.g., polyols). In some embodiments, the method comprises reacting glycerol in the presence of a fatty acid-containing compound and a metal catalyst to form polyglycerol. In other embodiments, the method comprises reacting glycerol and/or an alcohol in the presence of a fatty acid-containing compound and a metal catalyst to form a mixed ether.
(FR)
L'invention concerne une méthode de réaction de glycérol destinée à former un polyglycérol ou des éthers mixtes de glycérol ou d'autres alcools (p. ex. des polyols). Dans quelques modes de réalisation, la méthode consiste à réagir un glycérol en présence d'un composé contenant de l'acide gras et d'un catalyseur métallique pour former un polyglycérol. Dans d'autres modes de réalisation, la méthode consiste à réagir un glycérol et/ou un alcool en présence d'un composé contenant de l'acide gras et d'un catalyseur métallique pour former un éther mixte.
