Rasvahappometyylestereillä

Rasvahappometyyliesterit, often abbreviated as FAMEs (Fatty Acid Methyl Esters), are a class of chemical compounds derived from fatty acids and methanol. They are typically produced through a process called transesterification, where triglycerides (fats and oils) react with methanol in the presence of a catalyst. This reaction breaks down the triglycerides into glycerol and FAMEs.

FAMEs are most widely known as the primary component of biodiesel. Biodiesel is a renewable fuel that can be used in diesel engines, either as a pure fuel or blended with petroleum-based diesel. The properties of FAMEs, such as their viscosity, flash point, and energy content, are similar to those of petroleum diesel, making them a viable alternative.

Beyond their use as fuel, FAMEs also find applications in other industries. They can be used as solvents, lubricants, and as intermediates in the production of other chemicals, such as fatty alcohols and fatty amines. The specific properties of a FAME depend on the type of fatty acid it is derived from. For example, FAMEs from saturated fatty acids tend to be more solid at room temperature, while those from unsaturated fatty acids are typically liquid. The production of FAMEs can utilize a variety of feedstocks, including vegetable oils (like soybean, rapeseed, or palm oil), animal fats, and even waste cooking oils, contributing to their role in a more sustainable economy.
