Patent number: 6229054Abstract: 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 of organic or inorganic basic catalysts, 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.Type: GrantFiled: December 9, 1999Date of Patent: May 8, 2001Assignee: Cardolite CorporationInventors: Zhisheng Dai, Meng J.
