Sorption and catalytic hydrolysis of the herbicide diethatyl-ethyl [N-chloroacetyl-N-(2,6-diethylphenyl)glycine ethyl ester] on homoionic Na(+)-, K(+)-, Ca(2+)-, and Mg(2+)-montmorillonite clays were studied in aqueous media. The Freundlich sorption coefficient, K(f), measured from isotherms on clay followed the order of Na(+) approximately K(+) > Mg(2+) approximately Ca (2+). Analysis of FT-IR...

The study investigates the effect of aluminium oxide nanoparticles as an additive to Madhuca Indica (mahua) methyl ester blends on performance, emission analysis of a single-cylinder direct injection diesel engine operated at a constant speed at different operating conditions. The test fuels are indicated as B10A0.2, B10A0.4, B20A0.2, B20A0.4 and diesel respectively. The results indica...

Energy is vital to the profitable growth of every nation and stimulate new research. Only natural resources can meet growing energy demand in recent years, biodiesel has become very interested as well environmental advantages that it be combined with mineral diesel fuel any quantity. The research focuses on study replacement a safflower methyl ester. engine tests shall performed using ester DI ...

Under controlled-environment conditions, ethametsulfuron-methyl doses that inhibited growth by 50% (ED(50)) were >100 and <1 g of active ingredient (ai) ha(-)(1) for ethametsulfuron-methyl-resistant (R) and -susceptible (S) wild mustard, respectively. There were no differences between the two biotypes with regard to absorption and translocation of the herbicide. Three days after treatment, appr...

In the presence of the nonselective herbicide glyphosate (N-[phosphonomethyl]glycine), buckwheat (Fagopyrum esculentum Moench) hypocotyls and cultured cells of Galium mollugo L. accumulate an organic acid, which was identified as shikimate by mass-spectroscopy of its methyl ester. After growth in 0.5 millimolar glyphosate for 10 days, G. mollugo cells contained shikimate in amounts of up to 10%...

THE TITLE COMPOUND [SYSTEMATIC NAME: (methoxy-carbonyl-meth-yl)ammonium chloride], crystallizes as a salt, C(3)H(8)NO(2) (+)·Cl(-), with the charged species inter-acting mutually via strong and highly directional N(+)-H⋯Cl(-) hydrogen bonds which lead to the formation of a supra-molecular tape running parallel to the c axis. Tapes close pack in the solid state mediated by multipoint recognition...

There is considerable experimental evidence in support of the view that, in solution, the state of molecular dispersion of insulin is dependent on the net charge of the protein (10, 6, 8). In these investigations, alterations of the net positive charge were obtained by varying the pH of the solutions, with due consideration of the effect of the specific binding affinity of the protein for anion...

two modified methods for assaying sodium diclofenac were developed by gc and hplc. diclofenac was converted into methyl ester derivative by methyl iodide in acetone. the ester was extract and subjected to glc with flame ionization detector. %5 se-30/chrom w-hp (80-100 mesh) was used as a column in gc. for reversed phase hplc, the mobile phase was methanol and water (55-45). the separation was p...
