A fatty acid that can produce a white flame when burned is typically a long-chain saturated fatty acid. For example, palmitic acid (C16:0) and stearic acid (C18:0) are saturated fatty acids that, when combusted, can yield a bright white flame due to their higher carbon content and the nature of their combustion.
In general, the color of the flame during the combustion of organic compounds can depend on several factors, including the structure of
