Abstract
A method for the preparation of &ggr;-hydroxy ethers from cyclic organic carbonates and active-hydrogen-containing compounds in one form includes the steps of contacting an active-hydrogen-containing compound and a cyclic organic carbonate compound containing a six-membered ring, and a catalyst, running the reaction at a suitable temperature, and isolating the &ggr;-hydroxy ether as a mixture that can be purified or used directly as produced in the reaction.
