Does nitromethane have an octane rating?

Nitromethane: this is hard to quantify because nitromethane is an oxygenated fuel and they are also blended in different proportions with gasoline. Adding nitromethane actually decreases the equivalent octane rating.

What is the chemical formula for nitromethane?

CH3NO2
Nitromethane/Formula

Can you mix gasoline with nitromethane?

This means that nitro fuels carry two oxygen atoms as part of their chemical makeup. While nitromethane (CH3NO2) does not mix with gasoline, nitropropane (C3H7NO2) does. The whole object of an engine is to ingest air, which, when combined with the proper amount of fuel, creates a combustible mixture that makes power.

How much HP does nitromethane add?

With nitromethane, you only need 1.7 pounds of air. Drag racing motors are big, with an average engine displacement of 8.9 liters. When supercharged, they can produce about 6,000 horsepower.

Is methanol the same as nitromethane?

Nitromethane weighs more than methanol For the same volume, a heavier amount of fuel mixture is needed – that is represented by a smaller numerical air/fuel ratio. This means you will need more fuel per run than you did with straight methanol.

Does nitromethane go bad?

Absolutely It does go bad. It gets gummy or watery, but it has a pretty long shelf life. You can tell when nitro gets bad when it gets thick and gummy sometimes looke like water condensing in the bottle. Rule of thumb never use it after 1 year of sitting around.

How do you make nitromethane fuel?

Preparation. Nitromethane is produced industrially by combining propane and nitric acid in the gas phase at 350–450 °C (662–842 °F). This exothermic reaction produces the four industrially significant nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane.

Is nitromethane a fuel?

Nitromethane is a little like gasoline that has been pre-mixed with nitrous oxide. The fuel comes with its own oxygen atoms to help it burn. Pound for pound, nitromethane is less energetic than gasoline, but you can burn a lot more nitromethane in a cylinder. The net result is more power per stroke.

What is the highest octane fuel?

Retail gasoline stations in the United States sell three main grades of gasoline based on the octane level: Regular (the lowest octane fuel–generally 87) Midgrade (the middle range octane fuel–generally 89–90) Premium (the highest octane fuel–generally 91–94)

What happens if you put nitromethane in a car?

The big advantage of nitromethane is that you can get a lot more power from each explosion inside the engine. Pound for pound, nitromethane is less energetic than gasoline, but you can burn a lot more nitromethane in a cylinder. The net result is more power per stroke.

What is the best nitro fuel?

Fuels typically range in nitro content from 10 to 40%. For general all-around use, 20% nitro is the most popular and a good starting point.

How do you purify nitromethane?

Purification. Nitromethane is a popular solvent in organic and electroanalytical chemistry. It can be purified by cooling below its freezing point, washing the solid with cold diethyl ether, followed by distillation.
