Besides the compact membrane catalysts described in Section II, there are two types of composite membrane catalyst porous and nonporous. Composite catalyst consists of at least two layers. The first bilayered catalyst was prepared by N. Zelinsky [112], who covered zinc granules with a porous layer of palladium sponge. The sponge became saturated with the hydrogen evolved during hydrochloric acid reaction with zinc and at room temperature actively converted hydrocarbon iodates into corresponding hydrocarbons.

Notice the diversity in structure of lhe.se proton dunurs. They include the classical hydrochloric acid (reaction a). Ihc weakly acidic dihydrogen phosphate anion (reaction b). the ammonium cation as is found in ammonium chloride (reaction c), the carboxylic acetic acid (reaction d). Ihc cnolic form of phenobarbital (reaction e), Ihe carboxylic acid moiety of indomelhacin (reaction j), Ihc imidc of saccharin (reaction g). and the prolonaied amine of ephedrine (reaction h). Because all are proton donors, they mu.st be treated as acids when calculating the pH uf a solution or percent ionization of the drug. At the same lime, as nuted below, there are important differences in the pharmaceutical properties of ephedrine hydrochloride (an acid salt of an amine) and lho.se of indomelhacin. phenobarbital. or saccharin. 

Route (A) is the expected reaction route in neutral solvent. In the preparation of the piperidyl carbinol, in the presence of hydrochloric acid, reaction follows route (B), which may involve concurrent reduction of the ring and carbonyl group or may actually follow (A) or (C) with... 

Excess chlorine must be removed from the mixture prior to use to prevent THM formation. Somewhat larger amounts of chlorine dioxide, such as needed in pulp processing and textile bleaching, are generally prepared by reduction of chlorate with hydrochloric acid (reactions [VII] and [VUI]) ... 

Lenzi and Rapson (135) have demonstrated spectrophoto-metrically the presence of an intermediate—perhaps ICI2O2]—in the chloric acid-hydrochloric acid reaction. The overall mechanism is... 

This is a neutralization reaction between a strong acid and a solid hydroxide, that is, one that is insoluble in water. Write the conventional equation for the aluminum hydroxide and hydrochloric acid reaction. 

Co-ordinated Nitrenes.— The complex rm -[RuCl(Ng)(diars)2] reacts in hydrochloric acid to produce approximately equal numbers of molecules of [RuCl(NH3)(diars)g]+ and [RuCl(N2)(diars)a]+. When this reaction is carried out with N-labelled complex containing specifically Ru( N N N), the dinitrogen complex produced contains exclusively Ru( N N). This result is consistent with a co-ordinated nitrene (Ru N) intermediate, similar to those previously reported for reactions of ruthenium(m)-azide complexes. However, product and product-distribution comparisons between the ruthenium(ii)-and ruthenium(m)-azide plus hydrochloric acid reactions suggest that there must be some difference in mechanism between the complexes of the two different oxidation states. It is therefore proposed that for the rra j-[RuCl(N3> (diars)a] reaction the first step is protonation of the co-ordinated azide, which may occur at either end, followed by a split into Ng plus NH, which gives an ammonia ligand one way and a dinitrogen ligand the other ...
