alkyl imidazolines have been reportedly used in a wide range of industrial formulations with different applications. ethoxylated alkyl imidazolines with appropriate ethoxylation degrees can be used as antioxidants and retarders in the formation of peroxides resulting from oxidation in hydrocarbon media. in this work, ethoxylated imidazolines were shown to be more effective in hydrocarbon media ...

The first known demonstration of tunable terahertz-wave generation by difference-frequency generation of dual signal-wave quasi-phase-matched optical parametric oscillation was performed with periodically poled LiNbO(3) (PPLN) with a series of gratings. An organic ionic salt, 4-dimethylamino-N-methyl-4-stilbazolium-tosylate (DAST), was used as a nonlinear crystal. A compact terahertz-wave sourc...

This study was conducted to determine the effects of clofilium phosphate and bretylium tosylate on ventricular defibrillation threshold. Dogs were anesthetized with pentobarbital and subjected to repeated fibrillation-defibrillation episodes. Defibrillation thresholds were determined at 15-min intervals, using underdamped 5--6 msec sinusoidal current shocks, from 30 min before drug injection to...

Glycerol is a valuable co-product from oleochemical industry such as from fatty acid and biodiesel production. By having three hydroxyl groups in its molecule, glycerol can undergo chemical modifications that lead to many possible applications. This paper reports the tosylation process of glycerol with para-toluenesulfonyl chloride (p-TsCl). Reaction of glycerol with p-TsCl in the presence of a...

This work examines the use of new hydrophobic ionic liquid derivatives, namely octadecylammonium tosylate (ODA-TS) and oleylammonium tosylate (OA-TS) for corrosion protection of steel in 1 M hydrochloric acid solution. Their chemical structures were determined from NMR analyses. The surface activity characteristics of the prepared ODA-TS and OA-TS were evaluated from conductance, surface tensio...

The title compound, C(14)H(21)Br(2)N(2) (+)·C(7)H(7)O(3)S(-), features a salt of protonated bromhexine, a pharmaceutical used in the treatment of respiratory disorders, and the p-toluenesulfonate anion. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯Br and C-H⋯O hydrogen bonds.

A Pd-catalyzed intermolecular 1,2-carboamination route to indolines from N-aryl ureas and 1,3-dienes that proceeds under mild conditions in relatively nonacidic media, is presented. The in situ generation, or preformation, of a palladium tosylate emerges as a key parameter in gaining the requisite reactivity for the C-H insertion/carbopalladation/nucleophilic displacement process.

Cardiac arrhythmias following acute myocardial infarction are often fatal. Although commonly used antiarrhythmics are usually effective, some patients develop dysrhythmias that are refractory to these medications. This article discusses the use and contraindications of bretylium tosylate, a relatively new antiarrhythmic drug that has been shown to be effective in reversing dysrhythmias that wer...

7-Hydroxycoumarine undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding alkyl (E)-3-((2-oxo-2H-chromen- 7-yl)oxy)acrylate in good yields. When the reaction was performed by 3-hydroxyquinoline similar alkyl acrylates were obtained.
