Applications of
Hydrogen Peroxide and Derivatives
Here we see that at a molar ratio of 1:1.1:1 (hydrogen peroxide/hydrogen
bromide/2-nitrotoluene) over 90% selectivity to the benzyl bromide is observed at
a conversion of 76%. However, increasing the oxidant ratio to 3:3.2:1 (hydrogen ...
However, when handcuffed to hydrogen, its behavior is so satisfactory that you
should let it enter your home chemical laboratory and allow it to perform for you.
Uniting bromine with hydrogen yields hydrogen bromide, or hydrobromic acid ...
... HBr from water and these two elements directly. Bromine is dropped onto moist
red phosphorus and the mixture is then cautiously heated. Hydrogen bromide,
like hydrogen chloride, can be prepared directly from the elements: H2 + Br2(g) ...
