Abstract
Abstract Higher ratios of alcohol to gasoline (gasoline) are possible utilizing gasoline in combination with a mixture of alcohol, a ketone (e.g., acetone) and a small amount of an alkali metal carbonate, such as sodium carbonate, in finely divided form.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
A gasoline additive mixture consisting essentially of alcohol mixed with from about 3 to about 10 percent, based on the volume of said alcohol, a ketone having the general formula ##STR3## wherein R 1 and R 2 , which may be the same or different, are each an alkyl of 1 to 4 carbon atoms, and from about 0.3 to about 1.5 grams per gallon of said additive mixture of an alkali metal carbonate in finely divided form.
Claim 2
Dependent Claim
78 words
A gasoline additive mixture consisting essentially of alcohol mixed with from about 3 to about 10 percent, based on the volume of said alcohol, a ketone having the general formula ##STR3## wherein R 1 and R 2 , which may be the same or different, are each an alkyl of 1 to 4 carbon atoms, and from about 0.3 to about 1.5 grams per gallon of said additive mixture of an alkali metal carbonate in finely divided form.
Claim 3
Dependent Claim
21 words
The additive of claim 1 wherein said ketone is selected from the group consisting of acetone, methyl-ethyl ketone and mixtures thereof.
Claim 4
Dependent Claim
15 words
The additive of claim 1 or 2 wherein said alkali metal carbonate is sodium carbonate.
Claim 5
Dependent Claim
30 words
The additive of claim 1 or 2 wherein said ketone is present in an amount ranging from about 5 to about 9 percent based on the volume of said alcohol.
Claim 6
Dependent Claim
