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.

USE OF VEGETABLE AND APPROXIMATE OIL WASTE

Methods of using waste in the processing of vegetable and fusel oils - a solution of glycerin, amyl and isoamyl alcohols in order to obtain ethers based on them, and thus ensure their integrated processing and creating waste-free technology of these processes are proposed. The method of utilization of glycerin solution, which is a waste in the process of hydrolysis of vegetable oil, by its esterification with acetic acid to obtain a valuable ester - triacetin, which is widely used in many sectors of the economy is proposed.

Sustainable Adsorption Removal of Nickel and Chromium on Eco-Friendly Industrial Waste: Equilibrium Study

Adsorption of nickel and chromium was investigated using fuller’s earth. The experimental data were analyzed using five 2-parameter adsorption models and three 3-parameter models. The maximum adsorption capacities for nickel and chromium were 769 and 556 mg/g, respectively. The Langmuir isotherm model was found to have the best fitting indicating monolayer adsorption. The adsorption was found to have an exothermic nature.
