T HE practice of chemistry is concerned very largely with the carrying out of chemical reactions whereby new substances are produced from old. The substances entering into the reaction are'known as reagents, and the substances produced as products. One of the factors in chemical reactions which is subject to human control and manipulation is summarized in the Law of Mass Action. This law, in si...

This publication deals with the spatially resolved simulation of a sodium–iodine secondary battery. The anode compartment consists molten sodium and cathode contains high-conductivity metal disc as electrode an aqueous catholyte. latter comprises iodide, triiodide, dissolved iodine, ions. A finite volume approach is proposed to model transport processes electrochemical reactions focusing on pos...

A simplified technic for the determination of serum protein-bound iodine (PBI) is presented. Endogenouslylabeled 1131 PBI is completely recovered. The technic is basedon the method of Barker et al. (1) and includes the following modifications: The number of washesof the precipitated serum proteins are decreased. Unashed iodide standards are used in a sodium carbonate solution rather than an int...

Systemic acidosis induced by intravenous administration of hydrochloric acid lowered intraocular pressure in unanesthetized rabbits. Aqueous humor flow was reduced by approximately 50%, as measured by the iodide method and as calculated from tonographic data. Outflow facility, episcleral venous pressure, plasma osmolality, blood pressure, pulse, and body temperature were not altered by systemic...

1,2,4,5-Tetram ethylim idazole (3) is obtained by m etalation o f 2,4,5-trim ethylim idazole (2) with sodium in liquid am m onia and subsequent addition o f methyl iodide. 3 reacts w ith Lewis acids to form the com pounds M e4C 3N 2 BH3 (8) and M e4C 3N 2-E + (4, 5, 7, 10; E = Me, H, SiM e3, C(O)M e). The X-ray structure reveals the ionic nature o f pentam ethylim idazolium iodide (4) in the so...

a direct and an efficient conversion of a wide range of primary, secondary even tertiary alcohols to the corresponding iodides have been achieved under ionic liquid conditions. the method involves preparation of ionic liquid-based iminium chloride intermediate from dmf-like ionic liquid then stirring it with alcohol in present of sodium iodide. the higher yields of alkyl iodides were obtained w...

Sodium salt of chloride, bromide and iodide were used to elucidate the effect of the size of the anion on the binding to pharaonis halorhodopsin and its transport during the photocycle of this retinal protein. Spectroscopic titration revealed an apparent strong binding constant of 2 mM for chloride, 0.23 mM for bromide and 5 mM for iodide. In the case of iodide a second, week binding constant o...
