SDS of cas: 112-62-9In 2022, Welter, Rosilene A.;Santana, Harrson;de la Torre, Lucimara G.;Robertson, Mark;Taranto, Osvaldir Pereira;Oelgemoller, Michael published 《Methyl Oleate Synthesis by TiO2 Photocatalytic Esterification of Oleic Acid: Optimization by Response Surface Quadratic Methodology, Reaction Kinetics and Thermodynamics》. 《ChemPhotoChem》published the findings. The article contains the following contents:
Me oleate, an example of a FAME (fatty acid Me ester), was produced by oleic acid (OA) photoesterification with TiO2 and UVA light. Different parameters were evaluated and optimized: catalyst pretreatment, temperature (25-65°C), catalyst loading (1-30% weight/weightOA) and oleic acid : alc. molar ratio (1 : 3-1 : 55). Response surface quadratic methodol. obtained by central composite rotational design (RSM-CCRD) was used to evaluate the main operational conditions of the photoesterification process. A high conversion of 98% (±0.8) at 55°C, 20% TiO2 (weight/weightOA), and 1(OA) : 55(methanol) molar ratio was achieved. The photoesterification mechanism is furthermore proposed. The Langmuir-Hinshelwood kinetic model considered the forward and backward reaction as first-order fits with the best accuracy (R2 of 0.997). The thermodn. results (ΔG338.15K = -20.75 kJ/mol, ΔH = 13.75 kJ/mol, and ΔS = 0.47 kJ/mol.K) indicate that the operating conditions are important, both to supply the energy requirement of the reaction, but also to increase the miscibility of the reactants.Methyl oleate (cas: 112-62-9) were involved in the experimental procedure.
Methyl oleate(cas: 112-62-9) is an intermediate for detergents, emulsifiers, wetting agents, stabilizers, textile treatments, plasticizers for duplicating inks, rubbers, waxes etc.SDS of cas: 112-62-9 It is also used in biochemical research as a chromatographic reference standard.
