| Abstract: | Inulin esters were synthesized containing residues of ferulic, p-hydroxycinnamic, and vanillic acids with a maximum degree of substitution of 1.1. The inulin acylation was carried out with chlorides of 4-acetoxy derivatives of the corresponding hydroxyphenylcarboxylic acids in a heterogenic water-organic environment. The removal of the protecting acetyl group at the phenol hydroxyl was carried out by treating with pyrrolidine or ammonium acetate. The solubility of the esters obtained was evaluated. |
