Optimized procedures are described for the synthesis of methyl 9(R)-hydroxyoctadecanoate (2) and methyl 9-oxo-octadecanoate (3) based on Dimorphotheca pluvialis seed oil. Simple countercurrent separation and Oppenauer oxidation (benzoquinone, aluminum t-butoxide) were applied to prepare 2 and 3 ...

Methyl linolenate was separated from its analogues by a new extraction system constructed by solvent, imidazolium based ionic liquids and cuprous salt. Firstly, the effect of ionic liquid on the dissolution of CuCl in acetonitrile, N,N-dimethylformamide (DMF), methanol and water was evaluated by...

1H NMR spin–lattice and spin–spin relaxation times of isotropic solutions of n-octylammonium n-octadecanoate in deuterochloroform containing ca. 0.1–0.2% tetramethylsilane (v/v) at ca. 292 K are observed to vary with position of the functional group in the amphiphile ion-pair, and with solute...

Studies were carried out to evaluate the role of a C21-fatty acid ester; propyl octadecanoate (PO) for olfaction-mediated behavioral responses of urban malaria vector, Anopheles stephensi and dengue vector, Aedes aegypti mosquitoes using electroantennogram (EAG), flight orientation and ovipositi...

SummaryDuring gas chromatography on a polyester column, the principal effect of bromine substituents on a fatty ester molecule was to increase the retention time in proportion to the increase in molecular weight. Secondary effects arose from configurational isomerism. Methyl threo-9,10-dibromooa...

Reaction of di(p-isocyanatophenyl)methane (MDI, 4) with N,N′-di(2-hydroxyethyl)- (1b) or N,N′-di[2-(2′-hydroxyethoxy)ethyl]-4,4′-bipyridinium di(hexafluorophosphate) (1e) and other diols [oligo(ethylene glycol)s and poly(tetramethylene oxide)s] in the presence of bis(p-phenylene)-34-crown-10...

A series of 16- and 18-membered azo- and azoxythiacrown ethers have been synthesized by reductive macrocyclization of the respective bis(nitrophenoxy)oxaalkanes. The aromatic residues located in the polyether region of the molecule were introduced to macrocyclic skeletons and their affinities to...

The continuing investigation of SAR studies of 3-(2-hydroxyethoxy)-N-(5-benzylthiazol-2-yl)-benzamides as stearoyl-CoA desaturase-1 (SCD-1) inhibitors is reported. Our prior hit-to-lead effort resulted in the identification of 1a as a potent and orally efficacious SCD-1 inhibitor. Further optimi...

Poly(ethylene terephthalate) copolymers (abbreviated as PETS) that contain bis[4-(2-hydroxyethoxy)phenyl]sulfone (BHEPS) were prepared from dimethyl terephthalate (DMT), ethylene glycol (EG) (5–95%) and BHEPS (5–95%). The compositions and microstructures of the copolyesters were determined by ...

Experiments of the fish-shaped phase diagram for the ternary system water+n-dodecane+2-(2-n-hexyloxyethoxy)ethanol (abbreviated by C6E2 hereafter) under atmospheric pressure were performed at constant water/n-dodecane weight ratio (1/1) to locate the critical end points. The upper and lower crit...

The densities, ρ and the speeds of sound, u, for {2-(2-hexyloxyethoxy)ethanol (C6E2) + methanol, +1-propanol, +1-pentanol, and +1-heptanol} have been measured as a function of composition using an Anton-Paar DSA 5000 densimeter at temperatures (288.15, 293.15, 298.15, 303.15, and 308.15) K and ...

Simple dialkyl ethers (i.e, diethyl or dihexyl ether), in addition to undergo oxidative cleavage by reaction with methyl(trifluoromethyl)dioxirane or dimethyldioxirane, induce the decomposition of these oxidation reagents in a concentration dependent manner. The identification of compounds deriv...

Hydrotreatment of bio-based model compounds was investigated in a three-phase slurry reactor over pre-sulphided NiMo/γ-Al2O3 bifunctional catalyst. Experimental results were supported by comprehensive in silico studies. Mathematical microkinetic model was developed for mass transfer phenomena, ...
