Additional or alternative feedstocks are one of the major areas of interest regarding biodiesel. In this paper, the fuel properties of kenaf (Hibiscus cannabinus L.) seed oil methyl esters are comprehensively reported. This biodiesel is also relatively unique by containing small amounts of cycli...

Biodiesel, the mono-alkyl esters of vegetable oils, animal fats or other triacylglycerol-containing materials and an alternative to conventional petroleum-based diesel fuel, has been derived from a variety of feedstocks. Numerous feedstocks have been investigated as potential biodiesel sources, ...

Microalgae are potential raw materials for biofuel applications. In this work, microbial lipids from Choricystis minor var. minor were extracted with conventional solvents in a Soxhlet apparatus and with compressed fluids with or without the use of a co-solvent (ethanol or hexane). Also, the tot...

The search for alternative feedstocks for biodiesel as a partial replacement for petrodiesel has recently extended to castor oil. In this work, the castor oil methyl esters were prepared and their properties determined in comparison to the methyl esters of lesquerella oil, which, in turn, is see...

Poor oxidation stability of methyl esters is the major problem associated with its worldwide acceptance. As per the standards EN 14214 and prEN16091; and ASTM-D 7545-09 the oxidation stability limit should be 20 h for the blends and 8 h for neat methyl ester. One approach for increasing resistan...

The solubilities of tris(2,2,6,6-tetramethyl-3,5-heptanedionate) cobalt(III) (Co(thd)3) and chromium(III) (Cr(thd)3) in supercritical carbon dioxide (scCO2) were measured at temperatures ranging from 313 to 343 K. The measurements were carried out using a circulation-type apparatus with a UV–vi...

The potassium salt (13) of 2,3,4,5-tetrahydrodipicolinic acid, a key intermediate in the diaminopimelate (DAP) pathway to L-lysine (7), has been prepared by elimination of p-toluenesulphinic acid from the N-toluenesulphonyl derivative (12) of dimethyl cis-piperidine-2,6-dicarboxylate with simult...

The objective was to investigate the effects of dietary curcumin and acetylsalicylic acid (ASA) on the performance and physiological responses of broiler chickens under chronic thermal stress. One hundred and sixty day-old male chicks (Ross 308) were divided equally into 4 groups (each contained...

Potassium polyaspartate (A-5D K/SD) is proposed for use as a stabiliser in wine, with a maximum use level of 300 mg/L and typical levels in the range of 100–200 mg/L. Potassium polyaspartate (A-5D K/SD) tested negative in a bacterial reverse mutation assay performed in accordance with OECD TG 4...

In this study, vapor-liquid equilibrium (VLE) of CO2 in aqueous potassium salt of l-phenylalanine (K-Phe) was investigated. A high pressure solubility cell was used to measure the solubility of CO2 in aqueous solution of (10, 20 and 25) wt% K-Phe at 303.15, 313.15 and 333.15 K over a CO2 pressur...

A simple high-performance liquid chromatography-ultraviolet (HPLC-UV) method for estimating the daily intake of ferrocyanide (FeCN) ion from food-grade salts was developed and validated. The levels of FeCN ion in food-grade salts available in Korean markets were analysed. FeCN ion was detected i...

The addition of potassium ferrocyanide (K4[Fe(CN)6]) in table salt as anti-caking agent has a crucial role in preventing the formation of lumps. However, the excess of K4[Fe(CN)6] and its decomposers are harmful to both human health and environment. To date, there are still lack of suitable meth...

The fabrication and application of zinc ferrocyanide ion exchange compounds for use as inhibiting and sensing pigments in protective paints and primers for metals and alloys are described in this paper. A distinctive property of these ferrocyanide pigments is an ability to store corrosion inhibi...

A rapid, simple, and reliable HPLC method was developed and validated to determine the presence of ferrocyanide ions (FeCNs) in food grade salts. An analytical column coupled with a guard column and mobile phase comprised of sodium perchlorate and sodium hydroxide (NaOH) were employed at a detec...

Thermogalvanic systems represent a means to convert a temperature gradient into electricity, using only redox chemistry. However, the kinetics of electron transfer and physical mass transport of the redox couples are known limitations. In this study we present self-contained gelled thermogalvani...

The Ugi four-component-reaction (Ugi 4CR) allowed synthesizing bisamide from carboxylic acid, aldehyde, amine, and isocyanide in one-pot operation. However, introducing 2-isocyano glucose into the Ugi 4CR and investigating the inhibitory effects of Ugi adducts against radical-induced oxidation o...

Substitution reactions of some para-substituted anilines with 2-chloro-5-nitropyridine were carried out conductometrically in acetonitrile/dimethylformamide mixtures. The various thermodynamic parameters for the reactions have been reported and discussed along with the validity of the isokinetic...

A simple, fast, sensitive and stability-indicating derivative spectrofluorimetric method is presented for the assay of zopiclone (ZOP), a drug with hypnotic effect, and its main degradation product and major contaminant, 2-amino-5-chloropyridine (ACP). The method is based on measuring the inhere...

Single crystal growth of two inorganic-organic compounds, Bis[2-methylpyridine tetrachlorozincate] (MPCZ) and Bis[2-amino-5-chloropyridine tetrachlorozincate] (ACPCZ) has been achieved by two different methods i.e. Gel growth and Solution growth through slow cooling process.
