The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...

Detergent-solubilized and partially purified soybean peroxygenase was shown to actively catalyze, in the presence of alkylhydroperoxides as co-substrates, the epoxidation of mono- and polyunsaturated fatty acids such as oleic and linoleic acids. Octadecenoic acids were found to be better substrates than shorter mono-unsaturated fatty acids (C16:1 or C14:1), but the position of their double bond...

This report is based on the synthesis of thermoset resins from sunflower oil. Sunflower oil with an iodine value 120 g I / 100 containing 30 % oleic acid and 59 linoleic was epoxidized by reaction a peroxy (formed in-situ between hydrogen peroxide formic acid). The ratio ethylenic unsaturation to used 1:1.5:0.5. maximum conversion generated 82.45 for seven h epoxidation at 65 °C, oxirane oxygen...

The polymerization pathways of epoxidized and hydroxylated triglycerides with phosphoric acid (H3PO4) were investigated using model reactions. Involved epoxides and diols were derived from oleic acid methyl ester, which was easily monitored by oneand two-dimensional nuclear magnetic resonance (NMR) techniques as well as electrospray ionization mass spectroscopy (ESI-MS). Phosphoric acid played ...

Biobased omega-carboxy fatty acid monomers 1,18-cis-9-octadecenedioic, 1,22-cis-9-docosenedioic, and 1,18-cis-9,10-epoxy-octadecanedioic acids were synthesized in high conversion yields from oleic, erucic and epoxy stearic acids by whole-cell biotransformations catalyzed by C. tropicalis ATCC20962. Maximum volumetric yields in shake-flasks were 17.3, 14.2, and 19.1 g/L after 48 h conversion for...

Biolubricants, plasticizers, bio-based rigid foams, and non-isocyanate polyurethanes can be made in a green way from epoxidized fatty acids. The classical technology for acid epoxidation requires reaction carrier, which acts as the real agent. process is complicated involves safety risk because of appearance percarboxylic Therefore, direct acids presence an immobilized enzyme attractive pathway...

The evaluation of the temperature effect on the competitiveness between the amine addition and the amidation reaction in a model cure acid-catalysed reaction between the epoxidized methyl oleate (EMO), obtained from high oleic sunflower oil, and aniline is reported. The study was carried out analysing the kinetic profiles of the chemical species involved in the system, which were obtained apply...

Abstract A new oleic acid derivative plasticizer, epoxidized trimethylolpropane trioleate (EPO), has been synthesized and its application in PVC formulations compared with di(2-ethylhexyl) 1,2-cyclohexanoate (DOCH/DEHCH), a commercial phthalate-free plasticizer of petrochemical origin. EPO their blends DOCH were added to resin (50 PHR) the plasticized characterized by thermal mechanical measure...
