Abstract
The new millennium is marked by a growing search for renewable fuels and alternative raw materials from biomass in the petrochemicals industry. Thus, the preparation of fine chemicals and innovative materials from natural and renewable resources is an attractive topic for academic and industrial research especially when the purpose is to recycle huge amount of agro-industrial wastes. Cashew nut shell liquid (CNSL), well known by-product from the cashew industry rich in natural phenols, is widely produced in many countries (Africa, Brazil, India). Cardanol, obtained as the main product by vacuum distillation of the CNSL, has been used for the preparation of fine chemicals and hybrid materials [1, 2]. In the last years, different classes of compounds, such for example porphyrins, phthalocyanines, fullerenes cardanol based and others fine chemicals, have been synthesized from selected components of CNSL through environmentally sustainable strategies [1-5]. Moreover, innovative composites and hybrid cardanol based compounds have been used to design eco-friendly functional materials and processes [6-9]. References: 1) Mele G., Vasapollo G.
