## Abstract

A method includes the step of contacting an olefin, an alcohol, a metallosilicate catalyst and a solvent, wherein the solvent comprises structure (I) wherein R1 is selected from the group consisting of a hydrogen or an alkyl group and R2 is selected from the group consisting of an alkyl group or an alkoxy group.

## Claims

### Claim 1

A method, comprising the step:
contacting an olefin, an alcohol, a metallosilicate catalyst and a solvent, wherein the solvent comprises structure (I):
wherein R1 is selected from the group consisting of a hydrogen or an alkyl group and R2 is selected from the group consisting of an alkyl group or an alkoxy group.

### Claim 2 (depends on 1)

The method of claim 1, wherein the alcohol is selected from the group consisting of monoethylene glycol, diethylene glycol, glycerol or combinations thereof.

### Claim 3 (depends on 1)

The method of claim 1, further comprising the step of:
generating an alkylene glycol monoalkyl ether.

### Claim 4 (depends on 1)

The method of claim 1, wherein the olefin comprises a C12-C14 alpha-olefin.

### Claim 5 (depends on 1)

The method of claim 1, wherein the metallosilicate catalyst has a silica to alumina ratio from 10 to 300.

### Claim 6 (depends on 1)

The method of claim 1, wherein an alcohol to olefin molar ratio is 0.5 or greater.

### Claim 7 (depends on 1)

The method of claim 1, wherein the solvent is from 0.1 wt % to 85 wt % of the combined weight of the olefin, alcohol, and solvent.

### Claim 8 (depends on 1)

The method of claim 1, wherein R2 is an alkoxy group.

### Claim 9 (depends on 1)

The method of claim 1, wherein R2 is an alkyl group.

### Claim 10 (depends on 1)

The method of claim 1, wherein the solvent is selected from the group consisting of guaiacol, o-cresol, m-cresol, p-cresol, 1,2-dimethoxybenzene, 1,3-dimethoxybenzene, 1,4-dimethoxybenzene and combinations thereof.
