Within the depleting resources of fossil fuels and the increase in their price, in the recent past a lot of interest has been given to the use of plant oil specially the non-edible oil and its ester (biodiesel). Although the use of biodiesel in place of diesel has resulted in much lesser tail pipe emission, a substantial increase of NOx is reported by several researchers. It may be due to low c...

       Volatile constituents of the seed kernel and leaf of cultivated Moringa peregrina (Forssk.) Fiori, Agricolt collected after hydrolysis were analyzed by GC and GC/MS. Five glucosinolate degradation products which constituted almost the whole isolated oil of the seed kernel were identified to be: isobutyl isothiocyanate (94.0%), isopropyl isothiocyanate (4.9%), sec-butyl isothiocy...

Ruminants represent an important source of methane (CH(4)) emissions; therefore, CH(4) mitigation by diet supplementation is a major goal in the current ruminant research. The objective of the present study was to use a rumen simulation technique to evaluate the CH(4)-mitigating potential of pure compounds in comparison with that achieved with garlic oil, a known anti-methanogenic supplement. A...

This study examined the effects of a minimum quantity lubrication (MQL) and Cupric oxide- (CuO-) based nanofluid on Inconel 718 machinability. Additionally, by using an MQL CuO-based during turning process, 718’s tribological characteristics are optimised. The experimentation was done method. With aid magnetic stirring ultrasonic bath CuO nanoparticles were dispersed in distilled water, sunflow...

Antifriction synergies between an ionic liquid (IL) and nanopowders as additives of ester base oil were analysed at rolling conditions. For this aim, two nanodispersions based on hybrid combinations hexagonal boron nitride nanoparticles (h-BN) or graphene nanoplatelets (GnP) with tri(butyl) ethylphosphonium diethylphosphate in triisotridecyltrimellitate (TTM) the mixture TTM IL using tribometer...

As a green material, used date pits oil is increasingly utilized as inexpensive feedstock for ethyl ester (biodiesel) production. Waste date pits as a raw material are one of the highly produced agricultural wastes in Iran. This study investigated the effect of several procedure parameters including the ethanol/oil molar ratio, reaction temperature and amount of catalysts on the yield of the pr...

essential oils (eos) extracted from aerial parts of aster indamellus grierson, calamintha umbrosa benth. and erigeron annuus (l.) pres.were analyzed by gc, gc/ms. the major acetylenic constituent (cis-lachnophyllum ester) of e. annuus was isolated and characterized by 1h and 13c-nmr spectra. their toxicity and repellent effect against lipaphiserysimi was tested. oils of e. annuus and c. umbrosa...

Abstract Catalytic ester-interchange reactions, analogous to mutation and recombination, allow new sequence information be written statistically into poly(ester-imide) chains based on NDI (1,4,5,8-naphthalenetetracarboxylic diimide) units. Thus, both the insertion of cyclic ester cyclopentadecanolide (“exaltolide”) an NDI-based homopolymer quantitative exchange between two different homopoly(es...

This highlight review describes the recent development of an electrophile-triggered 1,2-metallate rearrangement organoboronic ester ate-complex, which proceeds through 1,2-difunctionalization carbon–carbon σ- and π-bonds, using strain energy as a driving force. Coupling reactions small ring carbocyclic boronic esters, such cyclopropyl-, bicyclo[1.1.0]butyl-, cyclopropenyl-boronic ester, are sum...

This paper presents a series of structural modifications of epoxidized ricinoleic acid for biolubricant to improve the cold flow behavior and oxidation stability of vegetable oils through measurement of pour point (PP) and oxidation onset temperature (OT) and signal maximum temperature (SMT) of each synthetic compound. The results showed that butyl 10,12-dihydroxy-9-behenoxystearate with bulky ...
