Azobenzene-Functionalized Ionic Liquids: Light-Responsive Surfactants With Catalytic Potential. [PDF]

open access: yesChemistryOpen
Surface‐active imidazolium‐based ionic liquids containing an azobenzene group exhibit different micellization properties upon photoisomerization. Applying a sulfonate tag to the azobenzene moiety profoundly affects the physicochemical behavior of both isomers in water.

Epoxidation of Soybean Oil and its Blend with Waste Cooking Oil Using H2SO4 as Homogeneous Catalyst

open access: yesChemical Engineering Transactions, 2023
Epoxidation of soybean oil is carried out at different conditions such as the feed ratio of C=C/CH3COOH/H2O2 (1:1:1, 1:1:2, 1:2:1, 1:2:2, 1:2:4), reaction temperature (50 °C, 65 °C) and reaction time (3–7 h). Physicochemical properties of the reagent and

Kinetic models of reaction systems for the in situ epoxidation of unsaturated fatty acid esters and triglycerides [PDF]

open access: yesHemijska Industrija, 2004
Mathematical models that describe the kinetics of reaction systems for the in situ epoxidation of unsaturated fatty acid esters or triglycérides with organic peracids are reviewed in this paper. The advantages and inadequacies of each model are discussed.
