From these dried char samples sulfonated acidic alysts were prepared by mixing 5 g of each char sample with 98% concentrated sulfuric acid in a closed cup autoclave and heated at 160 C for 6 h. To remove the unreacted sulfuric acid, the obtained alysts were …
Nitric acid, as a rule, does not carry on as an acid with metals to shape the comparing salt and free hydrogen. Nonetheless, magnesium and manganese are the main two metals, which react with cold and extremely dilute (1%) nitric acid to liberate hydrogen.
