## Abstract

A vehicle and method for storing ozone is disclosed. A vehicle made of a water miscible, organic compound of a glycol-containing chemical compound, a tertiary alcohol or a mixture thereof that is capable of receiving and containing ozone is disclosed. The method involves producing ozone gas, introducing the ozone-containing gas into a mixing vessel that contains the aforementioned organic compound, agitating the organic compound in the presence of the ozone-containing gas, wherein the ozone-containing gas is at atmospheric pressure or at a pressure of up to about 150 psig., and releasing the pressure if pressures in excess of atmospheric are used.

## Claims

### Claim 1

A process for producing a stable solution containing ozone gas, comprising the steps of:
a) introducing an ozone-containing gas into a mixing vessel containing a solution of a water miscible, organic compound selected from the group consisting of polyethylene glycol, diethylene glycol, triethylene glycol, polypropylene glycol, glycol ethers, a tertiary alcohol and a mixture thereof;
b) mixing said solution with said ozone-containing gas under pressure for a sufficient period of time until an ozone concentration in said organic compound is at least about 11 grams per liter to form a stable solution containing said ozone gas; and,
c) depositing said stable solution containing said ozone gas into a container for storage.

### Claim 2 (depends on 1)

The process of claim 1, further comprising the step of diluting said stable solution in water.

### Claim 3 (depends on 1)

The process of claim 1, wherein steps (a) through (c) are repeated at least once.

### Claim 4 (depends on 1)

The process of claim 1, wherein said stable solution further comprises acetic acid, t-butanol or combinations thereof.

### Claim 5 (depends on 4)

The process of claim 4, wherein said stable solution further comprises hydrogen peroxide.

### Claim 6 (depends on 1)

The process of claim 1, wherein said stable solution further comprises hydrogen peroxide.

### Claim 7

A process for placing ozone gas into solution, comprising the steps of:
a) introducing an ozone-containing gas into a compressor;
b) pressurizing said ozone-containing gas to above atmospheric pressure;
c) introducing said pressurized ozone-containing gas into a mixing vessel until an equilibrium pressure in said vessel is established with said pressure of said ozone-containing gas, wherein said vessel contains a solution of a water miscible, organic compound selected from the group consisting of polyethylene glycol, diethylene glycol, triethylene glycol, polypropylene glycol, glycol ethers, a tertiary alcohol and a mixture thereof;
d) mixing said solution with said ozone-containing gas until ozone of said ozone-containing gas dissolves in said solution to form a stable solution containing said ozone gas; and,
e) lowering said equilibrium pressure to atmospheric pressure.

### Claim 8 (depends on 7)

The process of claim 7, further comprising the step of diluting said stable solution in water.

### Claim 9 (depends on 7)

The process of claim 7, wherein steps (a) through (f) are repeated at least once.

### Claim 10 (depends on 7)

The process of claim 7, wherein said stable solution further comprises acetic acid, t-butanol or combinations thereof.

### Claim 11 (depends on 10)

The process of claim 10, wherein said stable solution further comprises hydrogen peroxide.

### Claim 12 (depends on 7)

The process of claim 7, wherein said stable solution further comprises hydrogen peroxide.
