Abstract
"Process for the preparation by synthesis of higher polyol ethers", of the general formula: ** (See formula) ** where mr can adopt any integer value within the range 0-10, the adopted values being equal or different from each other, and consisting essentially of the condensation of allyl halides and propargyl with appropriate alcohols in alkaline medium, oxidative dimerization of the terminal acetylenes formed and/or homologation with formaldehyde, followed by selective hydrogenation of the triple bonds to double bonds and total final hydroxylation of the double bonds, said steps being able to invert, repeat or omit any of them within a given synthesis sequence.
