“…CNSL is directly extracted from the shell of the cashew nut, fruit from cashew tree, anacardium occidentale. This tree from Brazil, is mostly grown in India, East Africa, and Brazil [8]. The total production of CNSL approaches one million tons annually [9] and CNSL is one of the few major and economic sources of naturally occurring phenols.…”

“…CNSL can be regarded as a versatile and valuable raw material for polymer production and represents a good natural alternative to petrochemicals derived phenols [10]. CNSL constitutes nearly 25% of the total weight of the nut and is composed of anacardic acid (3-n-pentadecylsalicylic acid) and smaller amounts of cardanol (3-n-pentadecylphenol), cardol (5-npentadecylresorcinol), and methylcardol (2-methyl-5-n-pentadecylresorcinol), the long aliphatic side-chain being saturated, mono-olefinic (8), di-olefinic (8,11), and triolefinic (8,11,14) with an average value of two double bonds per molecule ( Fig. 1).…”

Commercial epoxidized cardanol, from cashew nut shell liquid (CNSL), is a biobased epoxide reactant with interesting aromatic structure. Epoxidized cardanol was thoroughly analyzed using 1 H and 13 C NMR, size exclusion chromatography, and titration in order to determine the structure. This epoxidized cardanol was reacted with isophorone diamine and Jeffamine D400 diamine in order to synthesize epoxy networks. These epoxy networks, formulated in stoichiometry ratio, were characterized by differential scanning calorimetry, thermogravimetric analysis, dynamic mechanical analysis analyses and were compared to bisphenol A diglycidyl ether (DGEBA) network. Cardanol-based epoxy materials exhibit interesting mechanical and thermal properties for coatings.Practical application: The reactant described in this contribution, i.e. epoxidized cardanol from CNSL, provides biobased aromatic building blocks for further epoxy resin syntheses by reaction with amine hardeners. The obtained epoxy networks are partially biobased and may be applied as binders and coatings.

“…Thus, cardanol is gaining an increasing interest as natural source of phenol (Balachandran et al, 2011). Cardanol is produced from cashew nut shell liquid (CNSL), directly extracted from the shell of the cashew nut, fruit from cashew tree, anacardium occidentale, mostly grown in India, East Africa and Brazil (Ionescu et al, 2012). The global production of CNSL approaches one million tons annually (Campaner et al, 2009) and CNSL became of the few major and economic sources of naturally occurring phenols.…”

-This review proposes a platform approach for the synthesis of various building blocks from cardanol oil in one or two-steps synthesis. Cardanol is a natural phenol issued from Cashew nutshell liquid (CNSL). CNSL is a non-edible renewable resource, co-produced from cashew industry in large commercial volumes. Cardanol is non-toxic and particularly suitable as an aromatic renewable resource for polymers and materials. Various routes were used for the synthesis of di-and poly-functional building blocks used thereafter in polymer syntheses. Phenolation was used to dimerize/oligomerize cardanol to propose increase functionality of cardanol. Thio-ene was used to synthesize new reactive amines. Epoxidation and (meth)acrylation were also used to insert oxirane or (meth)acrylate groups in order to synthesize polymers and materials.Keywords: Cardanol / epoxide / acrylate / carbonate / amine / vinyl ester Résumé -Une approche plateforme de l'huile de cardanol : de la synthèse d'intermédiaires réactionnels à la synthèse de polymères. Cet article présente une approche plateforme de synthèse d'intermédiaires réactionnels variés pour l'élaboration de polymères à partir de cardanol. Le cardanol est un phénol naturel issu de l'huile de coque de noix de cajou -Cashew nutshell liquid (CNSL), une ressource renouvelable non-alimentaire coproduit de l'industrie de la noix de cajou. Le cardanol est non-toxique est particulièrement adapté pour l'intégration de noyaux aromatiques dans des polymers et des matériaux biosourcés. Différentes voies ont été envisages pour la synthèse d'intermédiaires réaction-nels di-et poly-fonctionnels pour la synthèse de polymères. La phénolation a été utilisée pour dimériser/oligomériser le cardanol pour augmenter sa fonctionnalité. Le couplage thio-ene a été utilize pour élaborer de nouvelles amines réactives. L'époxidation et la (méth)acrylation ont permis la fonctionnalisation groupes oxirane ou (méth)acrylate afin d'élaborer des matériaux.
