METHOD OF PREPARING GLYCEROL ALKYL ETHERS

摘要

A process for glycerol etherification, including 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).
