金属与酸反应的常用规律(The common law of the reaction between metal and acid) The common law of the reaction between metal and acid 1. the reaction of metals with acids is a redox reaction, and the amount of metal that loses electrons is equal to the amount of material that acids yield...
Metallic titanium is dissolved in an aqueous solution of telluric acid, the liquor evaporated, preferably at temperatures below 78 DEG C., to produce a sludge, the sludge dried to form a powder, and the latter heated to 800--1700 DEG C., the resultant product being cooled out of contact...

As an acid- and metal-free reagent, tert-butyl nitrite has many advantages like commercial availability, low toxicity, inexpensiveness, air- and moisture-stability, easy handing, mild reaction conditions and excellent regioselectivities. Since 2004, tert-butyl nitrite has become a hot research topic...
Moreover, the fraction of each metal species varies sensitively depending on the reaction condition. This can eventually alter their degree of participation as precursors in metal NC synthesis. Thus, to elucidate the formation mechanism of metal NCs and control their ensemble uniformity, it is ...
