Analysis of Products Obtained in Chemical Interesterification of Rapeseed Oil with Methyl Formate
Key Engineering Materials, 2019Chemical interesterification is one possible way to produce biofuel from vegetable oils. Rapeseed oil interesterification with methyl formate using 1M tBuOK catalyst in tBuOH yields product in two layers. The upper layer contains fatty acid esters. Analysis of lower layer by 13C NMR method shows that it contains glycerol and glycerol formates.

Catalyst Removal after the Chemical Interesterification of Sunflower Oil with Methyl Acetate
Organic Process Research & Development, 2017The efficiency of two processes to remove the potassium methoxide catalyst after the chemical interesterification of sunflower oil with methyl acetate was examined in this work. The two processes were acid neutralization and dry washing. Several acids were used as neutralization agents to form potassium salts.

Oxidative stability of soybean oil products obtained by regioselective chemical interesterification
Journal of the American Oil Chemists' Society, 1995AbstractOxidative stability of products produced as potential margarine basestock from soybean oil and methyl stearate by a novel chemical regioselective interesterification was evaluated. The oxidative stability of the products was evaluated by peroxide formation and volatile analysis during storage in the dark with oxygen at 60°C for 72 h.

Chemical interesterification of soybean oil and methyl acetate to FAME using CaO as catalyst
Fuel, 2020Abstract This study evaluated calcium oxide as catalyst from calcium carbonate at different calcination temperatures and the hydration-dehydration technique was used to produce a nanocrystalline catalyst. CaO samples were characterized by XRD, thermogravimetric analysis, Fourier transform infrared spectroscopy, scanning electron microscopy and ...

How is chemical interesterification initiated: Nucleophilic substitution or α‐proton abstraction?
Journal of the American Oil Chemists' Society, 2004AbstractEsters of carboxylic acids including 2‐methylhexanoic, 2‐methylbutyric, 2,2‐dimethyl‐4‐pentenoic, palmitic, and oleic acids were tested as substrates in methoxide‐catalyzed interesterification and transesterification. The aliphatic acid esters participated in the ester‐ester interchange upon addition of catalytic sodium methoxide.

AbstractFat blends, formulated by mixing a highly saturated fat (palm stearin or fully hydrogenated soybean oil) with a native vegetable oil (soybean oil) in different ratios from 10:90 to 75:25 (wt%), were subjected to chemical interesterification reactions on laboratory scale (0.2% sodium methoxide catalyst, time=90 min, temperature=90°C).
