发明名称 CARDANOL DERIVATIVE AND METHOD OF MAKING THE CARDANOL DERIVATIVE
摘要 The present invention comprises a process for the hydroxyalkylation of cardanol with cyclic organic carbonates in the presence of organic or inorganic catalysts and a novel composition of matter produced by that process. The unique molecular structure of cardanol allows the use of a variety or organic or inorganic basic cattalysts, including triethylamine, imidazol, sodium hydroxide and sodium carbonate, in the hydroxyalkylation reaction without forming quantities of undesirable side-products. According to this invention, the final product, monohydroxyalkylcardanyl ether, can be obtained with high yield and high purity. The product has a light color and its color stability is enhanced by replacing the phenol's hydroxyl group with a more stable hydroxyalkoxyl group.
