- These monomers are, for example, manufactured by chemical synthesis using C2-C4 olefins, cycloalkanes or benzene as raw material, but also castor oil (nylon 11), erucic or lesquerolic oil. (Nylon 13) ...
- the first consists of a methanolysis of castor oil in a basic medium producing methyl ricinoleate which is then subjected to pyrolysis to obtain, on the one hand, heptanaldehyde and, on the other hand, methyl undecylenate.
