A new synthesis of ω-hydroxy acids, which employs commercially available starting materials and lowers the cost of production. The process involves coupling a fatty acyl group by enamine chemistry, followed by a ring expansion and selective reduction of ketoacid.

ways to synthesize fatty acids, the chemical synthesis route offers more advantages in terms of versatility and targeted synthesis. Though remarkable achievements have been made in the field of fatty acid synthesis, it is still in the preliminary stage of optimization. In this paper, we wish to report a more practical & scalable approach for the synthesis of fatty acids with carbon atoms ranging from

A process for preparing an aqueous polymer dispersion, in which, in an aqueous medium, in a first reaction stage, a hydroxycarboxylic acid compound is reacted in the presence of an enzyme and of a dispersant, and also, if appropriate, of a low water solubility organic solvent and/or of an ethylenically unsaturated monomer, to give a polyester, and thereafter, in the presence of the polyester, in a second reaction stage, an ethylenically unsaturated monomer is free-radically polymerized.
