In 1752 the French chemist Pierre Macquer made the important step of showing that a dye called Prussian blue could be converted to iron oxide plus a volatile component and that these could be used to reconstitute the dye. The new component was what we now know as hydrogen cyanide. Following Macquer's lead, it was first isolated from Prussian blue in pure form and characterized about 1783 by the Swedish chemist Carl Wilhelm Scheele. In 1815 Joseph Louis Gay-Lussac deduced its chemical formula. The radical cyanide in hydrogen cyanide was given its name from the Greek word for blue, due to its derivation from Prussian blue.

What is the common name for HCN?
Hydrogen Cyanide
What chemical agent has smell of bitter almonds?
Cyanide smells of almonds.
What is the chemical name for hydrogen cyanide?
The correct name (after IUPAC rules) is just hydrogen cyanide.
How do yu make cyanide?
Cyanide is usually made using ammonia, methane, and oxygen with a platinum catalyst. 2CH4 + 2 NH3 + 3O2 --> 2HCN + 6 H2O The cyanide is in the form of hydrogen cyanide, which is liquid at room temperature, but will readily become a gas. The common solid, water-soluble forms of potassium cyanide (KCN) and sodium cyanide (NaCN) are made by reacting hydrogen cyanide with the corresponding hydroxide in water. For example: KOH + HCN --> KCN + H2O.
