Abstract
A method of generating an alkylene glycol monoalkyl ether includes the steps of contacting an olefin, an alcohol, a metallosilicate catalyst, and a solvent blend, wherein the solvent blend comprises from 30 wt % to 90 wt % of an oxygenated solvent based on a total weight of the solvent blend and 10 wt % to 70 wt % of a non-oxygenated solvent based on a total weight of the solvent blend; and generating the alkylene glycol monoalkyl ether.

A method of generating an alkylene glycol monoalkyl ether, comprising the steps of:
- contacting an olefin, an alcohol, a metallosilicate catalyst, and a solvent blend, wherein the solvent blend comprises from 30 wt % to 90 wt % of an oxygenated solvent based on a total weight of the solvent blend and 10 wt % to 70 wt % of a non-oxygenated solvent based on a total weight of the solvent blend;
- and
- wherein the oxygenated solvent is selected from one or more of cresols, o-cresol, m-cresol, p-cresol, phenol, guaiacol, methyl benzoate, dimethyl phthalate, diglyme, triglyme, diethyl phthalate, dibutyl phthalate, ethyl benzoate, trimethyl 1,2,4-benzenetricarboxylate, glyme, and dimethoxybenzene;
- wherein the non-oxygenated solvent is selected from one or more of xylenes, m-xylene, p-xylene, o-xylene, benzene, toluene, hexane, heptane, octane, nonane, undecane, dodecane, tridecane, tetradecane, pentadecane, hexadecane, cyclohexane, cycloheptane, cyclooctane, linear C6 to C16 alkanes, and cyclic C6 to C16 alkanes;
- generating the alkylene glycol monoalkyl ether.
