Abstract
Cashew nutshell liquid oil among different renewable resources is one of the agricultural byproducts available in tropical countries such as India that is used to produce cardanol as naturally occurring fatty phenols It has attracted great attention in advanced chemical industries to produce biopolymers biosurfactants biocomposites and nanomaterials It represents an excellent alternative feedstock for the elaboration of chemicals and polymers Moreover cardanol is regarded as a versatile and valuable raw material for wide applications in the form of brake linings surface coatings paints and varnishes as well as in polymer production In this chapter the possible modifications of cardanol to produce monomeric and polymeric surfactants have been discussed in different reaction schemes It can be recommended that because of their renewable nature and structural characteristics cardanol is likely candidates for preparing “green” surfactant species like anionic sulfonates nonionic ethoxylated and cardanol–formaldehyde ethoxylated polymers and cationic quaternary ammonium pyridinium and imidazolium derivatives to replace the petroleum based on nonylphenol surfactants Moreover it can be used to prepare biopolymer polymer nanocomposites and semisynthetic processes to prepare derivatives with biological and pharmaceutical applications
