As new biomass derived raw material, cardanol has attracted the attention of numerous academic and industrial groups due to its renewability and unique structural features. In this work, seven cardanol-derived quaternary ammonium compounds (QACs) were syn

Cardanol was obtained by vacuum distillation of ‘‘cashew nut shell liquid’’ (CNSL). Cardanol is a by-product of cashew production and a building block for chemical synthesis; cardanol and its derivatives can be used for different types of applications. Three of these compounds are the subject of the present NMR study and theoretical comparison. 1H and 13C NMR signals were assigned using 1D and 2D NMR experiments. The DFT/B3LYP method using the cc-pVTZ basis set was employed for the calculations of the 1H and 13C NMR chemical shifts (δ). The obtained data were used as an auxiliary tool for unequivocal assignment of all 1H and 13C NMR signals. For these compounds, the adopted theoretical model was sufficient to obtain a good description of the chemical shifts.

We report the synthesis and fluorescent properties of 1,4-disubstituted-1,2,3-triazoles (1a-c) based on pollutant wastes and by-products from the cashew and biodiesel industries as a design for fluorescent markers. The triazoles were synthesized in four steps; catalytic hydrogenation of cardanol, reaction with epichlorohydrin, azide substitution and/or epoxide opening and, Cu catalyzed click-chemistry of the azide with the ethynylanilines (6a-c). This procedure is a potential alternative to make fluorescent markers since it affords the intermediates in high yields, enabling one to produce the products in good quantities. Moreover, triazolazobenzenes (8a-c) were prepared by azo coupling of the trizoles (1a-c) with phenol to give a new option of dyes. Evaluation of the fluorescent properties of the achieved compounds showed that all triazole derivatives displayed good fluorescence emissions in the range of 325–400 nm, with a maximum of fluorescence intensity at around 350 nm when excited between 225 and 300 nm; besides, the para-triazolaniline exhibited a dual fluorescence emission, presenting an additional emission band in the blue range (400–500 nm).

A novel plasticizer derived from cardanol, and epoxied cardanol glycidyl ether (ECGE), was synthesized and characterized by 1H-NMR and 13C-NMR. The effects of ECGE combined with the commercial plasticizer dioctyl phthalate (DOP), in soft poly(vinyl chloride) (PVC) films, were studied. The mechanical properties of PVC films showed both tensile strength and percent elongation increases with increasing ECGE content. Thermogravimetric analysis (TGA) was performed to characterize the thermal stabilities of the plasticized samples and showed the stability of films increased on increasing the content of ECGE. The properties of volatility, extraction, and exudation resistance of plasticizers were tested and analysis by means of solubility parameters as reported in the literature suggests the ECGE has similar or higher stability for these properties than DOP. FTIR analysis of the films also revealed that ECGE interacted with PVC. Due to its inherent chemical backbone and the modified epoxy groups, ECGE properly balanced the properties and improved the performance of PVC films compared with the neat DOP plasticizer.
