Modification of chiral dimethyl tartrate through transesterification : immobilisation on POSS and enantioselectivity reversion in Sharpless asymmetric epoxidation [PDF]
Modification of dimethyl tartrate has been investigated through transesterification with aminoalcohols to provide reactive functionalities for the covalent bonding of chiral tartrate to polyhedral oligomeric silsesquioxanes.

Enabling Highly (R)-Enantioselective Epoxidation of Styrene by Engineering Unique Non-Natural P450 Peroxygenases [PDF]
Unlike the excellent (S)-enantioselective epoxidation of styrene performed by natural styrene monooxygenase (ee >99%), the (R)-enantioselective epoxidation of styrene has not yet achieved a comparable efficiency using natural or engineered oxidative ...

Epoxidação do óleo de soja com o sistema catalítico [MoO2(acac)2]/TBHP EM [bmim][PF6]
Epoxidation of soybean oil was investigated using 1-n-butyl-3-methylimidazolium hexafluorophosphate [bmim][PF6] ionic liquid as biphasic medium with molybdenum(VI) acetylacetonate complex and tert-butyl hydroperoxide TBHP as oxidizing agent.

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

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