Abstract
A method of forming an alkoxylated fluoroalcohol is accomplished by providing a boron compound having or providing at least one boron-oxygen bond and an iodine source. The boron compound and iodine source are combined with reactants of a fluoroalcohol and an alkylene oxide in the presence of a base. The reactants are allowed to react to form an alkoxylated fluoroalcohol reaction product.
Claims9
A method of forming an alkoxylated fluoroalcohol comprising combining:
- at least one boron compound selected from the group consisting of boric acid, boron oxide, a tetraborate salt, and an alkyl borate;
- iodine;
- a metal iodide;
- a base;
- and a fluoroalcohol together in a mixture,
- whereby the fluoroalcohol reacts with the boron compound to form a borate ester in situ,
- and then subsequently adding an alkylene oxide to the mixture and allowing reactants of the mixture to react to form an alkoxylated fluoroalcohol reaction product.
