Abstract: | A unique advanced intermediate: 3-Pentadecylcyclohexanone was synthetized from the crude product which contained a mixture of cardanol, cardol and 2-methylcardol, which was hydrogenated onto Pd/C at 80 °C. From this alkylated cyclohexanone: C15 alkylated adipic acid, caprolactam, caprolactone, were synthetized in high yields, such products may have many potentially applications in polymer chemistry. The condensation of the 3-pentadecyl-cyclohexanone and triethylene glycol in oxidative or reductive conditions gave aryl ether and cyclohexyl ether, this may be a way to prepare intermediate for surfactant chemistry. Therefore we show that Cashew Nut Shell Liquid (CNSL) may lead to numerous useful compounds thank to the preparation of a unique advanced intermediate. |
