Abstract
The present disclosure provides base aviation gasoline formulations. In addition, the present disclosure provides formulations in which one or more additives can optionally be added to the base aviation gasoline formulation to produce a finished aviation gasoline formulation.
Claims20
A finished aviation gasoline formulation comprising a) a base aviation gasoline formation comprising:
- i) dimethylbutane at a concentration between about 10% to about 40%;
- ii) trimethyl pentane at a concentration between about 50% to about 90%;
- iii) isobutane at a concentration between about 1% to about 5%, and
- b) a first additive selected from the group consisting of m-toluidine, aniline, or a combination of both, wherein the first additive is present in the finished gasoline formulation at a concentration between about 0.001% to about 5%.
1 more element
A finished aviation gasoline formulation comprising
- a) a base aviation gasoline formation comprising:
- i) dimethylbutane at a concentration of about 25% of the base aviation gasoline formation;
- ii) trimethyl pentane at a concentration of about 71.5% of the base aviation gasoline formation;
- iii) isobutane at a concentration of about 3.5% of the base aviation gasoline formation, and
- b) a first additive, wherein the first additive is selected from the group consisting of m-toluidine, aniline, or a combination of both, and wherein the first additive is present in the finished gasoline formulation at a concentration of about 2%, and
- c) a second additive, wherein the second additive is isobutanol, and wherein the isobutanol is present in the finished gasoline formulation at a concentration of about 3%.
