What You'll Learn
Nitromethane is highly volatile and dangerous
Nitromethane is a highly volatile and dangerous organic compound with the chemical formula CH3NO2. It is the simplest organic nitro compound and is used as a solvent in a variety of industrial applications. Due to its high volatility, handling and storing nitromethane can be hazardous. It is crucial to take necessary precautions, such as keeping it away from open flames and out of the reach of children.
One of the major hazards associated with nitromethane is its potential for explosion. In 1958, a railroad tank car loaded with nitromethane exploded, revealing its explosive nature, which is even more potent than TNT. This incident highlighted the dangers of adiabatic compression, a common hazard with liquid explosives, where rapid pressure changes can lead to unexpected detonation.
Additionally, nitromethane combustion produces nitric oxide (NO), a significant contributor to air pollution, acid rain, and ozone layer depletion. The high flame temperature of about 2,400 °C (4,350 °F) further exacerbates the risks associated with its use. Furthermore, nitromethane is listed as a hazardous substance by the U.S. Environmental Protection Agency (EPA), emphasizing its potential health and environmental risks.
When working with nitromethane, it is essential to prioritize safety. This includes wearing protective gear, such as gloves, and having fire safety equipment readily available. The highly flammable nature of nitromethane and its ability to burn with minimal atmospheric oxygen increase the risk of fire and explosion. Therefore, it is crucial to handle and store it with extreme caution.

Hazmat fees can be avoided by buying a diluted mix
Making your own RC car fuel can be a fun and cost-saving activity. However, it is important to exercise extreme caution when handling the necessary chemicals, such as methanol, nitromethane, and castor oil. Nitromethane, in particular, is highly volatile and flammable, often incurring additional Hazmat fees during shipping.
To avoid these fees, consider purchasing a diluted mix of nitromethane and methanol. For example, an 80%/20% mix (80% nitromethane and 20% methanol) can help you circumvent the Hazmat fees while still providing a suitable fuel blend for your RC car. This diluted mix is a more affordable option, costing around $13.75 a quart, compared to pure nitromethane, which can cost upwards of $45 plus shipping and Hazmat fees.
When purchasing the diluted mix, look for suppliers like FHS Supply Co. or consider ordering from companies like Torco Fuels. These companies often sell pre-mixed blends that meet the required specifications, saving you the hassle of mixing your own fuel. It is worth noting that methanol has unique surface tension characteristics, especially when in contact with metal. Therefore, using a spout or a large funnel can help mitigate the mess during the pouring process.
While making your own RC car fuel can be rewarding, it is crucial to prioritize safety. Always wear gloves and have a fire extinguisher nearby when handling these chemicals. Additionally, ensure that your work area is well-ventilated, and avoid inhaling the fumes as they can cause dizziness. Keep the chemicals away from children and open flames, and always store them in securely sealed containers, away from direct sunlight and extreme temperatures.
