Sulfonation of unsaturated fatty acid triglycerides for the production of surface-active substances

The paper describes the preparation of surface-active substances by sulfonation of unsaturated groups that are present in the composition of molecules of fatty unsaturated acids of triglycerides. Sunflower oil, chosen for its renewable and vegetable-based origin, served as the primary raw material. The method for producing sulfonated derivatives of fatty acid triglycerides is detailed, and the structures of the resulting products were verified using IR spectroscopy.

The Sulfonation of 3,5,7,3’,4’-Pentahydroxyflavone and Non-Linear-Optical Activity of its Sulfonic Derivatives

Synthesis of sulfoquercetin and studies of its structure and nonlinear properties have been carried out. Using quantum-chemical simulations, 13С and HSQC NMR spectrometry, FTIR spectroscopy it was shown that a sulphonic group occurs in C8 location of quercetin. Molecular first hyperpolarizability of the obtained 8-sulfoquercetin was studied. It was shown that 8-sulfoquercetin can be used for creation the new polymer NLO materials on its basis.
