Saturated and unsaturated long-chain dialkyl glyceryl ethers (2, 3-dialkoxy-l-propanols) were syiithesiaed by alkylation of tritylated alkyl glyceryl-(1) ethers (l-alkoxy-3-trityloxy-2- propanols) with methanesulfonates, followed by hydrolytic removal of the trityl groups. Trialkyl glyceryl ethers (1, 2, 3-trialkoxypropanes) containing three identical, or two or three different, alkyl groups were prepared.
