Abstract
Process for preparing an alkoxylated alcohol comprising reacting a starting monohydroxy alcohol selected from secondary alcohols, tertiary alcohols and mixtures thereof with an alkylene oxide in the presence of hydrogen fluoride and a boron-containing compound comprising at least one B—O bond. The alcohol may also be a primary monohydroxy alcohol when the boron containing compound is boric acid or boric acid anhydride or a mixture thereof, or may be a primary mono hydroxy alcohol, except a C14/C15 alcohol when reacted with ethylene oxide in the presence of HF and trimethyl borate. A phenol may be alkoxylated in the same way instead of the mono-hydroxyalcohol.
Claims20
A process for preparing an alkoxylated alcohol which comprises reacting a starting mono-hydroxy alcohol selected from the group consisting of secondary alcohols, tertiary alcohols, and mixtures thereof with an alkylene oxide in the presence of hydrogen fluoride and a boron-containing compound comprising at least one B—O bond.
A process for preparing an alkoxylated alcohol comprising reacting a primary mono-hydroxy alcohol with an alkylene oxide in the presence of hydrogen fluoride and a boron-containing compound comprising at least one B—O bond excluding a process which comprises reacting a C14/C15 alcohol with ethylene oxide in the presence of hydrogen fluoride and trimethyl borate.
A process for preparing an alkoxylated alcohol comprising reacting a primary mono-hydroxy alcohol with an alkylene oxide in the presence of hydrogen fluoride and a boron-containing compound comprising at least one B—O bond wherein the boron-containing compound is selected from boric acid, boric acid anhydrides, and mixtures thereof.
A process for preparing an alkoxylated phenol comprising reacting a starting mono-hydroxy phenol with an alkylene oxide in the presence of hydrogen fluoride and a boron-containing compound comprising at least one B—O bond.
