After the reaction, product was purified, and characterized by MS and 13C NMR spectroscopy, and determined as 6-O-(10-undercylenoyl)-D-glucose, The product was used as the starting material, K2S2O8 as a chemical initiator, to polymerize and form the sugar-containing polymer, which could be used for medicine release agent and other application of biological materials.
But, the UAVE used by Takao Raku is a special kind of chemicals reagent rather than chemical raw materials, the price of UAVE is expensive and difficult to obtain.Im the present study, we reported to use 10-undecylenoyl acid as starting raw material, because it is one of ricinoleic derivative, UA is cheaper and easily to be avalible.
By the initiator potassium persulfate, poly 6-O-(10 - undecylenoyl) - glucose ester could be synthesized, which can be used as biomedical materials.
