Reactions with mineral acids

Polymers having one or two carboxyl endgroups are prepared by anionic polymerisation and subsequent chain termination with C02+ and further reaction with mineral acids. 

A boiling, dilute solution of diammonium phosphate evolves ammonia (the pH of the solution decreases), which also occurs slowly at ambient temperatures. The solid and its solution create an ammonia vapor pressure. Reactions with mineral acids produce the corresponding ammonium salts. 

Reactions with mineral acids produce their cadmium salts. With hydrochloric acid, sulfuric acid and nitric acid, the products are cadmium chloride, cadmium sulfate and cadmium nitrate, respectively ... 

Cobalt(lI) hydroxide is oxidized by air and other oxidizing agents, forming cobalt(lII) hydroxide, Co(OH)3. Reactions with mineral acids produce corresponding Co2+ salts. 

Strong heating in air converts cobalt(III) oxide to tricobalt tetroxide. Reactions with mineral acids produce their Co3+ salts ... 

Thermal decomposition yields copper(II) oxide. Reactions with mineral acids yield the corresponding copper(II) salts ... 

In comparison the samples 0 2 2 3 and 4 have similar unit cell size and framework Si/AL However the NFA1 content of DUSY zeolite decreases with increasing adding speed of acid solution The obvious explanation for the observed decrease in NFA1 content is that NFA1 species occupy the micropore volume of the USY zeolite and are preferentially removed by reaction with mineral acid solution as follows t... 

Chrysophenine shows a characteristic reaction with mineral acids witli which it turns a beautiful blue. It is of interest, theoretically, that chrysophenine is an extraordinarily strong dye even though it contains no auxocliroiue groups of the type required by tlie Witt color theory.

The chemistry of the cellulosic fibers is similar to that of the simple sugars, but more complex, as the stereochemistry of the alcohol and hemiacetal structures is affected by degree of crystallinity, e.g., the -OFI groups on the carbon atoms 2, 3, and 6 have different reactivities. Reaction with mineral acids leads to cleavage of the glycosidic bond and formation of a reducing end (RO-CFI-OFI). 

J0rgensen prepared (6) bl compound called anhydrobasic tetraammine diaquodiammine cobalt chloride, which he believed to be a dimer involving an oxo bridge. Werner found that OH could not be bonded to Co in the usual way since it did not react with dilute mineral acid to give an aqua complex. Decomposition of the complex by reaction with mineral acid gave three moles of cw-[Co(H20)2(NH3)4]X3,... 

Returning to the problem at hand, both 2 and 3 react quickly and easily with HBr, so the ti-bonds in each molecule are considered to be good Br0nsted-Lowry bases in their reactions with mineral acids. Benzene does not react with HBr, even with heating. Benzene has six 7i-electrons 2 has only two, so benzene is more electron rich relative to 2. The fact that benzene does not react suggests that it is too weak a base, which is a good indication that the six p-electrons are held tightly by the molecule and are not available for donation. The poor basicity of benzene in a reaction with HBr is presented as evidence of the special stability of benzene, and the explanation for that stability is the resonance delocalization shown for 1C. 

HALS are known to undergo a reaction with mineral acids such as HBr causing an inhibition of activity. For this reason, success in using HALS in combination with co-additives capable of producing acids during processing or exposure has been quite limited. Examples of co-additives of this type are thios)mergists (distearyl-3,3 -thio-dipropionate, DSTDP) and brominated flame retardants. Unexpectedly, HALS-5 has shown an unusual chemical resistance when compared to traditional HALS.
