Glycerol Ether Synthesis: A Bench Test for Green Chemistry Concepts and Technologies

“…The synthesis of glycerol ethers was earlier studied in order to modify the hydrophilic (glycerol, diglycerol, triglycerol) and hydrophobic parts (branched or linear chains), allowing the possibility to develop a large class of compounds with useful biological and physical properties . Several studies have demonstrated their original surfactant properties compared to classical nonionic surfactants such as polyethylene glycols (PEGs) synthesized from petrochemicals. − For example, Aubry recently defined hydrotropic properties for some short alkylated chain glycerol monoethers (GMEs) .…”

Synthesis of Ethers by GaBr3‐Catalyzed Reduction of Carboxylic Acid Esters and Lactones by Siloxanes

“…Thus, it should be of great value to develop a simple and more sustainable method for the reduction of esters and especially triglycerides to give the respective ethers in good yields and avoiding the overreduction to alcohol. [11] Sakai applied the InBr 3 -catalyzed reduction using Et 3 SiH as reducing agent to methyl oleate 1 and methyl 10-undecenoate to give the ethers in 56 % and 72 % yield, respectively. [1b] It is remarkable that the C=C double bond, and especially the cisconfigured double bond of methyl oleate is retained.…”

First Attempt of Glycidol‐to‐Monoalkyl Glyceryl Ethers Conversion by Acid Heterogeneous Catalysis: Synthesis and Simplified Sustainability Assessment

“…Amongthese, glycerol represents one of the major worldwide drop-in chemicals. [9][10][11] As am atter of fact, the preparation of MAGEs through direct glycerole therification has been investigated by using both heterogeneous and homogeneous catalysts.
