What is the Difference Between MAPP Gas and Propane?

MAPP gas and propane are both fuel gases used for various applications, such as soldering and heating. The key difference between MAPP gas and propane lies in their composition and properties:

• Composition: MAPP gas (Methyl Acetylene-Propadiene Propane) is a combination of several hydrocarbon compounds, including propyne, propane, and propadiene. Propane, on the other hand, consists of propane molecules with the chemical formula C3H8.
• Flame Temperature: MAPP gas burns at a temperature of 3,730 degrees Fahrenheit, while propane burns at 3,600 degrees Fahrenheit. This makes MAPP gas a faster alternative to propane for soldering, as it heats copper faster and to a higher temperature.
• Energy Content: MAPP gas has a higher energy content than propane, which means it releases more energy when burned.
• Odor: MAPP gas has an acetylene-like odor, while propane has a distinct smell.

In summary, MAPP gas is composed of propyne, propane, and propadiene, and burns at a higher temperature than propane, making it a faster alternative for soldering. Propane, however, is more widely available and has a lower cost, making it a popular choice for various applications.

Comparative Table: MAPP Gas vs Propane

Here is a table comparing the differences between MAPP gas and propane:

Please note that MAPP gas is no longer available to the general public, and the term "MAPP" on modern gas tanks refers to a substitute gas, which is typically 100% propylene.
