“…Also, the long hydrocarbon chain makes these derivatives highly compatible with oils. These two structural characteristics prompted the use of phosphorylated cardanol derivatives as antioxidants additives for biodiesel, 242 mineral oils [243][244][245][246][247] or PMMA films. 248 The characterizations included TGA and DSC to evidence the initial decomposition temperatures of either pure or formulated additives.…”

International audienceOver the last few years, more and more papers have been devoted to phosphorus-containing polymers, mainly due to their fire resistance, excellent chelating and metal-adhesion properties. Nevertheless, sustainability, reduction of environmental impacts and green chemistry are increasingly guiding the development of the next generation of materials. The use of bio-based polymer matrices might allow the reduction of environmental impacts by using renewable carbon and by achieving more easily biodegradable or reusable materials. The aim of this review is to present both fundamental and applied research on the phosphorylation of renewable resources, through reactions on naturally occurring functions, and their use in biobased polymer chemistry and applications. In the first section, different strategies for the introduction of phosphorus-containing functions on organic backbones are described. In the following sections, the main families of chemicals based on renewable resources are covered: namely polysaccharides (cellulose, chitosan, starch, dextran etc.), biophenols (lignins, biobased phenolic compounds, cardanol etc.), triglycerides (oils, glycerol) and hydroxy acid compounds

Among the renewable resource materials, cashew nut shell liquid (CNSL) is considered as an important starting material due to its unique structural features, abundant availability and low cost. A large number of chemicals and products have been developed starting from CNSL by taking advantage of the three reactive sites, namely, phenolic hydroxyl, aromatic ring and unsaturation(s) in the alkenyl side chain. This comprehensive review deals with general information on CNSL, its purification and separation methods, reactivity and applications in polymer chemistry.

Devido à grande utilização do cardanol para o desenvolvimento de novos aditivos, o presente trabalho tem como objetivos apresentar a caracterização química do fósforo cardanol, a qual foi verificada utilizando-se FTIR e técnicas termoanalíticas (TG/DSC/DTA) e, a avaliação antioxidante do composto em um óleo lubrificante de base naftênica. Neste trabalho, os autores incluíram também o estudo térmico do fósforo cardanol por aquecimento em estufa, com monitoramento das alterações em FTIR. De acordo com os resultados, o fósforo cardanol apresentou boa estabilidade térmica quando comparado a outros ésteres de fosfato de mesma classe e, não apresentou alterações antes e após aquecimento a 120 ° C, sob atmosfera de ar. Desta forma, o composto de fósforo obtido a partir do cardanol apresenta potencial de aplicação, como aditivo, em óleos lubrificantes e produtos petroquímicos do mesmo segmento. Palavras-chave: LCC, oxidação, estabilidade térmicaDue to the wide use of the cardanol to develop new additives, this study presents the chemical characterization of phosphorus cardanol using FTIR and Thermoanalytical techniques (TG / DSC / DTA), and the evaluation of the antioxidant potentiality of compound when added to a lubricating oil. In this paper, the authors also included the thermal study of phosphorus cardanol by heating in an oven, monitoring changes in FTIR. According to results, the phosphorus cardanol showed good thermal stability when compared with other compounds of the same class "phosphate esters" and showed no changes before and after heating at 120 ° C, under air atmosphere. Thus, the phosphorus compound derived from cardanol has potential application as additive for lubricating oils and petrochemicals of the same segment.
