Abstract:
1. A method for producing alkoxy polyol ethers comprising providing a polyol or polyol derivative comprising a salt of a polyol or a ketal or acetal of a polyol which comprises at least one free hydroxyl moiety and one or more ketal or acetal moieties, reacting said polyol or polyol derivative with a first alkylating agent under conditions effective for alkylation of one or more hydroxyl moieties of said polyol or polyol derivative to produce a first alkoxy polyol ether comprising one or more alkoxy moieties and spent first alkylating agent, recovering said spent first alkylating agent, and regenerating said spent first alkylating agent, wherein said regenerating comprises reacting said spent first alkylating agent with an alkyl orthoester and said first alkylating agent comprises a first alkyl tosylate.
