Tsuchiya, a 30-year-old organic chemist, told police that he experimentally a produced the deadly nerve agents VX, soman, and tabun, as well as the poisons hydrocyanic acid and mustard gas, the Asahi said.

Nitroglycerine was also produced in the factory, and the group also intended to make hydrocyanic acid from potassium cyanide, initially purchased in weak form from Gupta and later in a stronger concentration from elsewhere.

His fearless nature towards the highly toxic hydrocyanic acid can be best be shown by a quotation from him : If you are used to handling the substance it is no worse than handling alcohol.

In Schr�dinger's thought experiment, a cat trapped in a sealed box is killed by a flask of hydrocyanic acid, but by the principles of quantum mechanics is considered to be both alive and dead at the same time.
25.
In inorganic cyanides, such as sodium cyanide and potassium cyanide this group is present as the negatively charged polyatomic "'cyanide ion "'( CN " ); these compounds, which are regarded as salts of hydrocyanic acid, are highly toxic.
26.
As an example, the lack of information about whether MIC could thermally decompose to hydrocyanic acid led to years of contentious debate on the merits of treating the gas victims for cyanide poisoning and an unfortunate violation of patient confidentiality.
27.
The mechanism of this Kr�hnke-type reaction likely proceeds via a vinylogous cyanamide "'23 "'which undergoes elimination of hydrocyanic acid, deprotonation to form enamine "'24 "'and cyclization to form intermediate "'25 "', which is then dehydrated to from the desired pyridine product.

The maximum safe dose of protactinium in the human body is 0.03 �Ci that corresponds to 0.5 micrograms of 231 Pa . This isotope, which might be present in the air as aerosol, is 2.5 times more toxic than hydrocyanic acid.
29.
Luciano Caprino, an expert in pharmacology at Rome's La Sapienza University, said potassium ferrocyanide itself is not toxic, " but if heated up to about 500 degrees C ( 932 F ), it can emit hydrocyanic acid, which is highly toxic ."

Poisoning by hydrogen cyanide gas within a gas chamber ( as a salt of hydrocyanic acid is dropped into a strong acid, usually sulfuric acid ) is one method of executing a condemned prisoner as the condemned prisoner eventually breathes the lethal fumes.
