In the field of flame synthesis, precursor means the substance before chemical reaction. However, in the field of soot, precursor is used for the monomers like PAHs, aromers that nucleate towards soot, fullerene and other carbon materials.
Which understanding is right?
Or if I use precursor as the substance before chemical reaction, is the route from PAH to soot a nucleation or reaction process?
In chemistry, a precursor is a compound that participates in a chemical reaction that produces another compound, or a chemical substance that gives rise to another more important chemical product.
Among the precursors used for the production of carbon fibers:
ex. Acrylic Precursors, PAN Precursors.
A presursor is a chemical substance which contains, in the right proportions, all of the ingredients that are required to make a desired chemical reaction move forward.
